Abstract

The invention provides a ceramic binding agent, which belongs to the technical field of adhesives and comprises, by mass, acetic acid ethenyl ester 10%-15%, sodium silicate 5%-7.5%, aluminum powder 2%-3%, sodium aluminate 5%-10%, methyl vinylsiloxane rubber 15%-20%, phenolic resin 10%-15%, ethyl acetate 10%-15% and the balance water. The ceramic binding agent is high in temperature-resisting performance and balanced in texture and strength after being bonded. In addition, the ceramic binding agent can be bonded between ceramics, can be used for bonding various materials including woods, metal, plastics and the like, and is wide in application range and convenient to use.

Description

A kind of ceramic binder and working method

Technical field

[0001] the present invention relates to technical field of adhesive, the ceramic binder of the bonding multiple material of especially a kind of strong effect.

Background technology

[0002] pottery has had the history more than 10000 years, and Chinese are at the pottery of invention just at the Neolithic Age, and pottery does not absorb water because of it and the characteristic of corrosion-and high-temp-resistant fully; Received people and used widely, to the modern times, along with development of productivity; Various advanced persons' the working method and the use of main equipment; Make material abundant greatly, pottery has also obtained great development, and ceramic applications has arrived each corner of people.Various ceramic binders also arise at the historic moment, and ceramic binder generally is divided into three types of ceramic organic binder bond and ceramic inorganic adhesive and metal-powder caking agents; The high-temperature resistant of organic binder bond usually all between the 100-250 degree, the highest 400 degree that generally are no more than, heatproof is too low; The temperature resistant range of inorganic adhesive is usually between 600-1750 degree centigrade; Though its heatproof is higher, the use of ceramic inorganic adhesive is loaded down with trivial details, and the bonding of the more suitable small and exquisite ceramic of inorganic binder particle; The pottery inorganic adhesive all is hard usually, and rigidity is crossed frangible by force; The metal-powder caking agent is mainly aluminium powder, selling at exorbitant prices; These three kinds of tackiness agents mainly are bonding between pottery, and its bonding scope is narrower.

Summary of the invention

For above-mentioned problem; The object of the present invention is to provide a kind of ceramic binder; Its heatproof was higher when this ceramic binder bondd between pottery and pottery, and its bonding back quality, intensity are comparatively balanced, and this ceramic binder various types of materials such as pottery and timber, metal, plastics that can also bond; Applied range, easy to use.

This reality invention solves the technical scheme that its technical problem adopted: this ceramic binder comprises and gathers vinegar vinyl acetate, water glass, aluminium powder, sodium aluminate, methyl vinyl silicone rubber, resol, ETHYLE ACETATE, water that the massfraction of various materials is: comprise and gather vinegar vinyl acetate: 10%-15%; Water glass: 5%-7.5%; Aluminium powder: 2%-3%; Sodium aluminate: 5%-10%; Methyl vinyl silicone rubber: 15%-20%; Resol: 10%-15%; ETHYLE ACETATE: 10%-15%, all the other are water.

Ceramic binder is the thickness body, best results during bonding porcelain, and being applied in during use needs on the bonding object, compresses the two articles bonding place and leaves standstill two to three hours and get final product.

As preferably, the said vinegar vinyl acetate of gathering is with minuteness particle group, and particle diameter 0.1-2.0 μ m are present in the tackiness agent.

As preferably, said aluminium powder diameter is less than 50 μ m.

As preferably, said resol is soluble phenolic resin.

The present invention also provides a kind of working method of said ceramic binder, comprises following production stage:

One, Xiang Shuizhong proportionally adds aluminium powder, water glass, sodium aluminate successively, stirs;

Two, adding ETHYLE ACETATE stirs;

Three, mixing solutions described in the step is heated to 50 ℃-70 ℃, adds and gather the vinegar vinyl acetate, stir;

Four, adding resol stirs;

Five, under nitrogen environment, add methyl vinyl silicone rubber and stir, under 50 ℃ of-70 ℃ of temperature, left standstill 90-120 minutes;

Six, cooling back nitrogen environment encapsulation preservation down.

Beneficial effect of the present invention is: the heatproof that this ceramic binder is higher; Make this ceramic binder be applicable to wider bonding scope, its bonding back quality is softer, intensity is higher makes the object after bonding that certain shock resistance comparatively firmly arranged, but this ceramic binder matrix material is extensive; Comprise timber, metal, plastics or the like; This ceramic binder is the thickness body, and setting time is moderate, and is easy to use.

Description of drawings

Fig. 1 is the structural representation of each composition quality fraction scale of ceramic binder.

Among the figure: 1, gather the vinegar vinyl acetate; 2, water glass; 3, aluminium powder; 4, sodium aluminate; 5, methyl vinyl silicone rubber; 6, resol; 7, ETHYLE ACETATE; 8, water.

Embodiment

Below in conjunction with accompanying drawing and embodiment the present invention is further specified:

As shown in Figure 1; Ceramic binder of the present invention comprises and gathers vinegar vinyl acetate 1, water glass 2, aluminium powder 3, sodium aluminate 4, methyl vinyl silicone rubber 5, resol 6, ETHYLE ACETATE 7, water 8 that the massfraction of various materials is: comprise and gather vinegar vinyl acetate 1:10%-15%; Water glass 2:5%-7.5%; Aluminium powder 3:2%-3%; Sodium aluminate 4:5%-10%; Methyl vinyl silicone rubber 5:15%-20%; Resol 6:10%-15%; ETHYLE ACETATE 7:10%-15%, all the other are water 8.

This ceramic binder is the thickness body, best results during bonding porcelain, and being applied in during use needs on the bonding object, compresses the two articles bonding place and leaves standstill two to three hours and get final product.

The said vinegar vinyl acetate 1 of gathering is with minuteness particle group, and particle diameter 0.1-2.0 μ m are present in the tackiness agent, when particle its adhesive capacity in this scope of polyvinyl acetate resin 1 the strongest.

Said aluminium powder 3 diameters are easy to mix less than 50 μ m like this, have higher binding property.

Said resol 6 is soluble phenolic resin.

Said ceramic binder can carry out according to following process step when producing:

One, in water 8, proportionally adds aluminium powder 3, water glass 2, sodium aluminate 4 successively, stir;

Two, adding ETHYLE ACETATE 7 stirs;

Three, mixing solutions described in the step 2 is heated to 50 ℃-70 ℃, adds and gather vinegar vinyl acetate 1, stir;

Four, adding resol 6 stirs;

Five, under nitrogen environment, add methyl vinyl silicone rubber 5 and stir, under 50 ℃ of-70 ℃ of temperature, left standstill 90-120 minutes;

Six, cooling back nitrogen environment encapsulation preservation down.

This ceramic binder has metal simple-substance, inorganics and organism to combine jointly, has three's advantage separately, and higher heatproof is arranged; Its bonding back quality is softer, intensity is higher, makes that the object after bonding comparatively firmly has certain shock resistance, and the certain proportion of various adhesive substances mixes; Make this ceramic binder except that bonding pottery; Also can bonding timber, metal, plastics or the like material, this ceramic binder setting time is moderate, easy to use.
