Problems solved by technology

[0004] However, because the main chain of silane-modified polyether in MS nail-free glue is polyether, it is lacking in heat resistance. Chinese patent CN 101906246B discloses a one-component heat-resistant silane-modified sealant , by using phenyltrimethoxysilane, the phenyl group is introduced into the main chain of silane-modified polyether, thereby improving the heat resistance of silane-modified polyether, but the introduction of phenyltrimethoxysilane will lead to silane The modified polyether becomes brittle as a whole, and its elastic performance decreases. Therefore, there is an urgent need to develop a low-VOC environmental-friendly nail-free glue for construction with good heat resistance, good water resistance, good initial viscosity and high elasticity.

Abstract

The invention provides a low-VOC environmentally friendly nail-free glue, more specifically a low-VOC environmentally friendly nail-free glue for home decoration and a preparation method thereof. The raw materials include 60-85 parts of silane-modified polyether, 35-70 parts of plasticizer, 60-90 parts of filler, 0.1-3 parts of catalyst and 2-25 parts of modified calixarene. Green and environmental protection, no isocyanate, good initial adhesion, high strength, durable. The calix[8]arene derivative is used in the formula, which has good heat resistance. Because the calix[8]arene derivative has a large cavity, it can meet the needs of high water seepage resistance; after curing, the calix[8]arene derivative The material can move freely in the network structure, which significantly enhances the elasticity; in addition, the calix[8]arene derivative and the silane-modified polyether are entangled together, which can achieve the effect of standing stickiness.

Description

Technical field[0001]The present invention relates to the field of architectural sealing rubber, more specifically a low VOC environmentally friendly nail rubber and preparation method.Background technique[0002]With people's aesthetic demand, modern building interiors generally adopt a glue-stick method to replace the traditional screws and nails, and this glue is called exewit rubber. Heshuped adhesive, also known as liquid glue, mainly for bonding new lightweight environmentally friendly energy-saving decorative materials, high-grade wall floor, door line, high-grade stone and tile, indoor prefabricated wall, stairs installation, cabinet and bath cabinet installation, etc. It is better to use chemical linking effect and higher efficiency. It is not only aesthetically effective, but also avoids noise and dust pollution, but also reduces the destruction of the housing structure, so it is more widely used.[0003]At present, traditional exemption gums in the market contain solvents, hi...
