Problems solved by technology

[0006] The technical problem to be solved by the present invention is: to overcome the defects in the prior art that the ordinary self-adhesive latex has insufficient adhesion, poor water resistance, easy to become cloudy, and cannot solve the problem of cold resistance, and the use of oily glue is unsafe and costly, and provides Three kinds of water-based self-adhesive latex products with different uses and excellent cold resistance that can completely replace oily glue and their applications, and at the same time provide a kind of water-based self-adhesive latex that can dissolve xylene-modified resins, rosin-modified resins, natural rubber or synthetic rubber with cold-resistant properties. Method for producing cold-resistant self-adhesive latex products by changing its oiliness to water-based and emulsifying and dispersing

Embodiment 1

[0080] Embodiment 1 Prepare 1# cold-resistant self-adhesive latex as follows:

[0081] (1) First put 400Kg octyl acrylate and 0.5Kg benzoyl peroxide into the stainless steel tank of the fast stirring emulsifying machine to dissolve;

[0082] (2) 10Kg solid content is 100% natural rosin denatured phenolic resin R-100 and puts into the stainless steel tank of the fast stirring emulsifying machine and immerses in dissolving;

[0083] (3) Stir and dissolve the natural rosin denatured phenolic resin with a 3600 R.P.M fast stirring emulsifier, take a sample after about 30 minutes, clamp the test solution with 2 transparent glass test pieces, check whether the solution is completely dissolved, until it is completely dissolved and there are no particles;

[0084] (4) Put 10Kg of reactive emulsifier ELEMINOL JS-2 with a solid content of 40%, and then stir it with a 3600 R.P.M fast mixer for 30 minutes, then take a sample and clamp the test solution with a transparent glass test piece t...

Abstract

The invention relates to three watercrafts self-viscosity latex product with superior cold tolerance, and its usage. Meanwhile, it offers a manufacturing method of cold tolerance self-viscosity latex product, which can be described as follows: dissolve xylene denatured resin, rosin denatured resin, natural rubber, or synthetic rubber, in order to change its oiliness into watercrafts, and then make it have emulsification and dispersion. One feature of the invention lies in the use of a kind of reactivity emulsifier that can take combined polymerization reaction with monomer; another feature lies in that it acquires the cold tolerance by dissolving xylene denatured resin, rosin denatured resin, natural rubber, or synthetic rubber, in order to change its oiliness into watercrafts, and by making it have emulsification and dispersion. The cold tolerance self-viscosity latex has the advantages such as initial adhesion, high adhesion in winter, fine water resistance, low cost, no evocative fire hazard, more safety, better environmental protection, better guarantee of worker's health, so it can substitute oiliness rubber and solvent form Alec Rubber completely.

Description

technical field [0001] The invention belongs to the field of organic chemical polymer polymerization fine chemical adhesives, and relates to three kinds of water-based self-adhesive latex products with excellent cold resistance and their application and a modified method for producing cold-resistant self-adhesive latex. Background technique [0002] The self-adhesive latex currently produced, due to the use of general emulsifiers, the emulsifier molecules cannot be copolymerized with other monomers in the micelles, so the adhesiveness of the produced latex is limited, and there is emulsification between molecules. The gap between the agent molecules reduces the adhesion, so that the water-based adhesive has lower adhesion than oil-based adhesives, poor water resistance, and easily turns white when it meets water. So far, water-based latex cannot achieve the adhesion properties of oil-based rubber or solvent-based acrylic adhesives. It is not much different in summer and can ...
