The polyethylene of component (e) and polyethylene and ethylene copolymers are mainly used in the multipolymer that helps dispersion rubber and ethene and ethylenically unsaturated carboxylic acids, also help to obtain desired physicals, as anti-intensity and shock strength.This component also is that the gratifying humidity resistance of acquisition is necessary.With regard to the application of most of automobiles aspect, preferred amount ranges is 5 to 40% (weight), most preferably 5 to 25% (weight).With regard to the product that obtains high modulus in flexure, should adopt HDPE with regard to the product that obtains low modulus in flexure, should adopt ionomer resin.
When adopting injection molding method, the melt index of component (e) is about 0.1 to 20, preferably is about 0.8 to 2.0.
Also can add various other materials in polymer blend of the present invention, these materials can comprise other compatible polymkeric substance, pigment, dyestuff, processing aid, anti static additive, tensio-active agent and the stablizer that is used in usually in the polymer composition.To improving the humidity resistance of these blends, especially effectively material is styrene-maleic anhydride copolymer and multiple cats product.The consumption of these a small amount of components respectively is lower than 2.0% (weight), is preferably lower than 1.0% (weight).They provide bigger move place for the physicals optimizing, also keep good clagging power simultaneously.
Various mixtures of material in component of enumerating in the above and the proportional range also can be used, and this is understandable naturally.For example, polypropylene component of the present invention can be various polyacrylic blends or mixture, for example blend of homo-polypropylene and various polypropylene copolymers.
Various component of the present invention can be carried out blend or mixing with conventional mixing device (as the Banbury mixing machine) and extruding mixing device.Be appreciated that blend polymer of the present invention can first blend, granulate then, make it be easy to storage, shipment and use subsequently.
Can adopt any known method,, polymer blend of the present invention be made useful articles as extruding, injection molding, blowing or thermoforming.Preferable methods is an injection molding.
The result that photomicrography analyzes is carried out in the cross section of the injection-molded item of polymer blend of the present invention show, in described goods, exist polymeric matrix with common external phase.We are reluctant to be bound by theory, and think that this structure is caused by more a spot of crystalline polypropylene in these blends and a large amount of filler.
The polymer blend that contains the filler that does not have the thorough mixing thing on a small quantity also demonstrates the flaky texture form except that having common external phase.When having only the thinner thickness when each layer or thin slice, observe the impact specimen surface with photomicrography usually and this flaky texture seen, could produce gratifying clagging power and physicals.When this thin layer thickening, shock strength and clagging power all reduce.We think that preferred construction is common external phase and thin slice combination mutually, and the latter's amount should be reduced to minimum.This class formation can by use filler and carefully the viscosity of selective polymer component obtain and control.
In case blend is processed into moulded products, these goods apply with regard to the coating of available routine, preferably apply with those coating that contain such composition, this composition be enough to blend in hydroxy-acid group reaction or its molecular weight be high enough to make on its polymeric matrix that is bonded to coating.As mentioned above, these compositions can comprise melamino-formaldehyde resin, epoxide, carbodiimide, enamine, ketoimine, amine, isocyanic ester or any have can with the material of the functional group of hydroxy-acid group reaction.
The additive pre-treatment of the goods of moulding available energy and carboxylic acid reaction before applying coating is with improvement clagging.This processing can comprise priming paint (as epoxy or urethane priming paint) and their component.Coating will adhere to and form competent and nonabradable upper layer on this goods, and this upper layer has performances such as antistripping, shatter-resistant, anti-super-humid conditions and anti-gasoline.Have found that polymer blend of the present invention is particularly suitable for producing the goods of urethane-polyester coating coating of using such as PPG Industries Durethane700HSE (high solid enamel paint).
Preferred coating system is with melamine formaldehyde (MF) linking agent (as the Cyme1303 of U.S. Cyanamid company production) or other urea resin solidified.The required storing temperature of this coating is about 250 °F.Though also available lower storing temperature makes coating crosslinked, can not be lower than usually 250 °F so that the melamino-formaldehyde resin of the carboxylic acid of matrix and coating react.
The composition of coating system is important.Some additive and pigment can be adsorbed on the acidic matrix, thereby stop the generation of required reaction to having reacted restraining effect.By using the priming paint that does not contain any undesirable additive can obtain uniform result.Then, available various coating system is coated in the outside of priming paint.
If carefully select coating system, also can obtain fabulous result when then on the goods of invention, adopting single coating (no priming paint).

When the test piece that the preparation applying coatings is used, at first use methylethylketone (MEK) to clean the surface of test piece.After surface evaporation, with PPG Industries DurethaneHSE 9440 enamel paint coatings test piece twice, it is all complete with the surface-coated of test piece whenever to blow spraying, allows 1.5 to 2 minutes flash-off time between per twice spraying with the method for spraying at MEK.The build of coating is approximately 1.5 to 1.8 mils.Durethane HSE 9440 coating are a kind of highly filled elasticity enamel paint, and it is made of polyester urethane main chain.Behind surface-coated two coatings of test piece, test piece 250 bakings 30 minutes, is made the paint solidification in the test piece.
Carry out four kinds of tests below respectively, with the performance of accepting coating of evaluation test piece.
Test I
In first kind of test, apply coating and evaluate clagging power after 24 hours, its method is to cut X type intersection lines with scraper in test piece, the edge of a knife is cut the surface of paint film up to the contact test piece.Then Permacel P-703 adhesive tape is attached on the cut surface, nail is depressed adhesive tape or with the back side of the rubber friction adhesive tape of wiping pencil it is depressed simultaneously.Adopt then make adhesive tape with test piece surface condition at an angle of 90 under the method peeled off rapidly peel off adhesive tape.After peelling off adhesive tape, check the situation of peeling off of test piece topcoating.Record intersection lines are peeled off the number of square and the ratio of total square number (common 25) in the zone.This first kind of test used as a kind of rapid screening method, to evaluate various blends and various coating system.
Test II
In second kind of test of evaluation clagging power, adopt the solvent-resistance test method.This solvent-resistance test is referred to as " Fisher-Body " method in automotive industry, when carrying out this test, the test piece that has been coated with coating is immersed in the mixed solution of 55% petroleum naphtha and 45% toluene.In stone internal organs oil-toluene mixture liquid, soak after 10 seconds, take out test piece, and with it air drying 20 seconds.In drying cycle, nail on probation or blunt knife blade coating the surface of coating.This test piece alternately soaked in petroleum naphtha-toluene 10 seconds and air drying 20 seconds, examination was simultaneously scraped, and repeats many times this circulation, carries out solvent-resistance test.Remove if any any coating when examination is scraped, promptly stop test.Remove the result that the required cycle index of carrying out of coating is solvent-resistance test from test piece.
Test III
The third test is under high humidity, adopts and evaluates the adhesivity of coating to polymer blend of the present invention by the test piece of above-mentioned steps applying coatings.It is 30 ℃ that the test piece that has applied coating is placed on temperature, and humidity is in 100% the humidity cabinet.Place and take out test piece after 96 hours, check the foaming situation of coating, any variation of obfuscation situation or coating appearance.Intersect lines with scraper cutting X type then, the edge of a knife is cut the surface of paint film up to the contact test piece, and Permacel P-703 adhesive tape is attached to the zone of cutting, down pressurizes with nail simultaneously or with the rub back side of adhesive tape of the rubber of wiping pencil.Employing make adhesive tape with test piece surface condition at an angle of 90 under the method peeled off rapidly peel off adhesive tape.Coating peelled off in record from cutting zone square number with intersect the ratio of the total square number in lines zone.When carrying out this moisture-resistant test, the inspection of test piece outward appearance and clagging power will be taken out from humidity cabinet in back 10 minutes in this test piece and be carried out.
Test IV
The 4th kind of test is to measure " the required power of coating bar that (1 inch) is wide of peeling off 1 from test piece.During on-test, " wide article tape is pressed on the surface that has been coated with coating with 1.Rule on the direction opposite with pulling force in each limit along adhesive tape.The front end of provoking coating with sharp metal blade begins from this test piece release coating.Peel off at the beginning, just adhesive tape is bonded at the back side of the coating of peeling off and is fixed on the mobile anchor clamps of lnstron equipment.The Instron equipment that use has an ergometer of 0 to 20lbs with test piece direction stretching coating at an angle of 90.With thickness is that the measured value of the coating of 1.5 to 2.0 mils is up to 5.0lbs/in.Test I is the used method of automotive industry evaluation coating durability, and the adhesion value that the coating of gained is peeled off is at most 0.7lbs/in.But adhesion value in some cases, only is that the coating of 0.3lbs/in just can be by test I.Obviously, this forces coating to penetrate some softer matrix owing to scraper often, thereby makes that adhesive tape is difficult to coating is left behind.
Adopt the automotive industry criterion, the adhesion value be 0.81bs/in or higher just can think very competent.
Among most of embodiment below, adopt any method all coating can not be stripped down from matrix.
In the form of the following example, " P " expression is qualified, and " F " expression is defective, and " NP " shows that paint can not be stripped from.
