Abstract

The invention discloses a heat-resistant and waterproof building binder. The heat-resistant and waterproof building binder comprises the following components in parts by weight: 160-170 parts of an ethylene-ethyl acrylate copolymer, 3-4 parts of palm wax, 1-2 parts of acetylated lanolin, 17-20 parts of a water-resistant aid, 0.7-1 part of methyltin mercaptide, 0.1-0.2 part of lithium laurate, 3-4 parts of bisphenol A phosphite and 0.1-0.3 part of 2,2'-ethylhexyl thioglycolate. The water-resistant aid prepared from maleic anhydride through graft modification is added into the raw materials, ethyl silicate is used as a precursor to prepare silica sol with excellent water resistance, and the aid with efficient water resistance is prepared from silica sol through fluorine-containing silane treatment. By utilizing palm wax and acetylated lanolin, the binding strength of the building binder can be improved, the consistency of the materials among copolymers can be further improved, and the overall performance is improved.

Description

technical field [0001] The invention relates to an adhesive, in particular to a heat-resistant and waterproof building adhesive and a preparation method thereof. Background technique [0002] At present, in the field of construction, the adhesives used for bonding between wood, stone, concrete, ceramics, glass, foam plastics, and metals are mainly chloroprene-phenolic adhesives. This kind of adhesive has the following disadvantages. First, during the construction process, the curing speed is slow, which will affect the construction progress. Second, it has poor water resistance and is easy to crack with water. Third, it is poor in environmental protection and easy to cause pollution. The comprehensive performance of construction adhesives is an important part of the development of construction business. Contents of the invention [0003] The invention overcomes the disadvantages of the prior art and provides a heat-resistant and waterproof building adhesive and a preparat...
