Problems solved by technology

[0002] Most of the adhesives commonly used in the market now contain harmful components such as benzene, toluene, xylene, and formaldehyde. After the house is decorated, it will cause indoor pollution and damage people's health. Modern decoration advocates environmental protection. Therefore, The environmental protection of adhesives has been put on the agenda, and it is imminent to develop an environmentally friendly adhesive for building materials

Abstract

The invention provides a building adhesive and a preparation method thereof. The building adhesive comprises a natural plant resin, borax, sorbitol, redispersible latex powder, a furfural resin, a glycidol ether reactive diluent, a defoaming agent, polysulfide rubber, water glass and a KS25 bactericide. The preparation method comprises the following steps: preparing the materials according to the formula; adding the components into a reaction kettle in a trickle mode at normal temperature, heating to 45-55 DEG C while stirring and mixing sufficiently, stopping heating after the temperature rises to 65 DEG C, and reacting; and after 3 hours, sampling, detecting the viscosity and pH value, and cooling and canning the acceptable product. The adhesive has the advantages of high binding force, high safety, no toxicity, high stability, long storage period and low cost, and can not generate environmental pollution.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a construction adhesive and a preparation method thereof. Background technique [0002] Most of the adhesives commonly used in the market now contain harmful components such as benzene, toluene, xylene, and formaldehyde. After the house is decorated, it will cause indoor pollution and damage people's health. Modern decoration advocates environmental protection. Therefore, The environmental protection of adhesives has been put on the agenda, and it is imminent to develop an environmentally friendly adhesive for building materials. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art, and provide a kind of strong cohesive force, safe and non-toxic construction adhesive and its preparation method. [0004] To achieve the above object, the present invention adopts the following technical solution...
