Description of drawings
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments:
Fig. 1 is the process figure that the present invention is used for the hot-melting type environmental protection pressure sensitive adhesive preparation method of double sticky tape.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that protection scope of the present invention is made more explicit defining.
Fig. 1 is the process figure that the present invention is used for the hot-melting type environmental protection pressure sensitive adhesive preparation method of double sticky tape; This preparation method comprises the steps: a) proportioning raw material, b) fusing viscosity increaser, c) glue, d) aftertreatment.
Embodiment
Concrete preparation method is as follows:
A) proportioning raw material should comprise for the raw material that the hot-melting type environmental protection pressure sensitive adhesive of double sticky tape is selected: viscosity increaser, toughner, softening agent, oxidation inhibitor and anti-aging agent; Each component by the quality proportioning is: viscosity increaser 40%, toughner 20%, softening agent 35%, oxidation inhibitor and anti-aging agent 5%.Wherein, viscosity increaser is hydrogenation C5 petroleum resin, and this hydrogenation C5 petroleum resin are formed by the modification of C5 hydrogenation of petroleum resin; Hydrogenation C5 petroleum resin are as a kind of low relative molecular mass, thermoplastic resin, not only safety, environmental protection, and have pour point depression, increase glutinous and improve the performance of viscosity, it is used for the viscosity increaser of thermotropic pressure sensitive glue prescription, can play and improve the colloid original viscosity, improve the effects such as colloid wettability; Although the C5 petroleum resin also have the advantages such as excellent property, safety, environmental protection, the C5 petroleum resin are in the process of formulation optimization and upgrading, and color is darker, contain unsaturated link(age), very easily oxidation in reaction process finally causes the product color produced dark, and is mobile relatively poor; Toughner is the SBS thermoplastic elastomer, the melting viscosity of its major effect pressure sensitive adhesive and stripping strength; Oxidation inhibitor and anti-aging agent can improve the oxidation-resistance of pressure sensitive adhesive as auxiliary agent, overcome the shortcomings such as poor heat stability.
B) fusing viscosity increaser, its melting process is: first to adding 40% hydrogenation C5 petroleum resin in the four-hole bottle of reflux, electric mixing device, then constant temperature oil bath is transferred to 80 ℃, begin heating, when temperature is 170～180 ℃, viscosity increaser begins fusing, melts 10～20min under this temperature, reaches fully fusing.
C) glue, glue comprises the steps: 1) add the softening agent stirring reaction; Detailed process is: add 35% softening agent in the first viscosity increaser after fusing, then fully stir, churning time is 10～15min; Add softening agent and can improve the reactive force between polymer molecule in the pressure sensitive adhesive, increase bonding strength, thereby increase the original viscosity of glue; 2) add oxidation inhibitor and anti-aging agent stirring reaction, the add-on of oxidation inhibitor and anti-aging agent is controlled at 5%, and churning time is 10～15min, adds the oxidation-resistance that oxidation inhibitor and anti-aging agent can improve pressure sensitive adhesive, overcomes the shortcomings such as poor heat stability; 3) add the toughner stirring reaction, the add-on of toughner SBS thermoplastic elastomer is 20%, wants rapid stirring after the adding, stirs 20～30min post-polymerization and finishes, and forms at last uniform and stable viscous liquid, gets final product plastic emitting; Add the SBS thermoplastic elastomer and have good tensile strength and elasticity, tension set is little, it is good to subdue with rebound resilience, skin friction force is large, to colloidality can lifting good effect is arranged.
D) aftertreatment, postprocessing working procedures comprises: cool off, detect, cut and pack; Above-mentioned steps c) the uniform and stable viscous liquid that makes in will be put into the forming box cooling forming; This hot-melting type environmental protection pressure sensitive adhesive finished product is through the mensuration of the performances such as original viscosity, melting viscosity, stripping strength, and its original viscosity is 8/NO, and greater than industry standard 6/NO, melting viscosity is 1.8/PaS, and less than industry standard 2.1/PaS, stripping strength is 8.75/Ncm
-1, greater than industry standard 7.5/Ncm
-1, measurement result shows: the performance of this environment-friendly type hot melt pressure sensitive adhesive is not only led over industry standard, and performance is better compared with similar products.
The present invention has disclosed a kind of hot-melting type environmental protection pressure sensitive adhesive for double sticky tape and preparation method thereof, the preparation technology of this hot-melting type environmental protection pressure sensitive adhesive is reasonable, the enforcement link is simple, not only transparent color and luster, outward appearance and original viscosity are good for the hot-melting type environmental protection pressure sensitive adhesive that makes, and nontoxic, pollution-free, when peeling off not pickup treat front cover.
The above; it only is the specific embodiment of the present invention; but protection scope of the present invention is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the present invention; variation or the replacement that can expect without creative work all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
