Abstract

The invention belongs to the technical field of waterproof building materials and in particular discloses a preparation method of waterproof glue. The preparation method comprises the following steps:firstly, preparing ethyl acetate-ethylene copolymer emulsion; A, preparing a PAV solution; B, preparing a pre-emulsified solution; C, preparing an oxidant solution; D, polymerizing the emulsion; secondly, preparing a waterproof glue base material; thirdly, preparing the waterproof glue. The waterproof glue prepared by the method provided by the invention has better imperviousness, high tensile strength and great elongation at break.

Description

Technical field The invention relates to the technical field of waterproof building materials, in particular to a preparation method of waterproof glue. Background technique At present, two types of waterproof materials have been developed for the problem of building leakage, namely, flexible waterproof materials (waterproof coils, waterproof coatings, etc.) and rigid waterproof materials. Flexible waterproofing is mainly installed on the outer surface of the building by laying or brushing to form a water-repellent layer. This kind of waterproofing method has defects such as weak adhesion to the substrate and easy damage. Rigid waterproof materials are mainly made of cement, sand, etc., forming a dense waterproof layer on the surface of the building matrix. However, the current rigid waterproof material has poor coordination with the substrate, and it is easy to cause the waterproof layer to crack when the substrate is deformed or shaken. For this reason, waterproof glue came...
