Abstract

The invention relates to anti-crystallization type modified epoxy resin for a sealant as well as a preparation method and application of the anti-crystallization type modified epoxy resin. The anti-crystallization type modified epoxy resin comprises the following raw materials in parts by weight: 100 parts of basic epoxy resin, 0.8-2.8 parts of bisphenol A, 0.05-0.5 part of a first catalyst and 0.05-0.5 part of a second catalyst, wherein the basic epoxy resin comprises bisphenol A epoxy resin and / or bisphenol F epoxy resin, the epoxy equivalent of the basic epoxy resin is 165-185 g / mol, the first catalyst is selected from one or more of tetrabutylammonium bromide, ethyl triphenylphosphine ammonium bromide and butyl triphenylphosphine ammonium bromide, and the second catalyst is selected from one or more of tetrabutylammonium bromide, ethyl triphenylphosphine ammonium bromide and butyl triphenylphosphine ammonium bromide. The second catalyst is selected from one or more of tetramethylammonium chloride, benzyltrimethylammonium chloride and benzyltriethylammonium chloride. The anti-crystallization modified epoxy resin is good in anti-crystallization performance in a low-temperature environment, the anti-crystallization crack beautifying agent prepared from the anti-crystallization modified epoxy resin still has high construction efficiency in the low-temperature environment, the construction difficulty can be reduced, and material and labor waste caused by resin crystallization can be reduced.

Description

Technical field [0001] The present invention belongs to the field of adhesives, in particular to anti-crystalline modified epoxy resins for american suture agents and preparation methods and applications thereof. Background [0002] With the vigorous development of the home improvement market, home tile caulking with epoxy resin seam quietly rises, epoxy resin seam agent has the characteristics of high strength, waterproof and oilproof and dustproof, and colorful, can be fully customized according to the home improvement style, to meet people's growing demand for a better life, in the home improvement market led a number of trends. [0003] In the construction process, the construction of the American joint agent requires epoxy resin glue to be mixed quickly and evenly and can ensure a certain construction cycle. However, in the low temperature environment, the U.S. sewing agent will have the phenomenon of bursting pipe and hardening, the U.S. sewing agent of the burst pipe will ...
