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 low-VOC environmentally friendly nail-free glue, particularly low-VOC environmentally friendly nail-free glue used for home decoration and a preparing method thereof. Raw materials include 60-85 parts of silane modified polyether, 35-70 parts of a plasticizer, 60-90 parts of a filler, 0.1-3 parts of a catalyst and 2-25 parts of modified calixarene. The glue is green, free ofisocyanate, good in initial adhesive force, high in strength and durable. A calix[8]arene derivative is adopted in the formula so that heat resistance is good. The calix[8]arene derivative has largehollow cavity so that a requirement of high-degree seepage proofing can be met. After curing, the calix[8]arene derivative can freely move in a network structure, thus significantly increasing elasticity. In addition, the calix[8]arene derivative intertwines with the silane modified polyether so that an effect of instant adhesion can be achieved.

Description

technical field [0001] The invention relates to the field of building sealant, and more specifically relates to a low-VOC environmental-friendly nail-free glue for home decoration and a preparation method thereof. Background technique [0002] With people's demand for aesthetics, modern architectural interiors generally use glue to replace traditional screws and nails, so this glue is called nail-free glue. Nail-free glue, also known as liquid glue, is mainly used for bonding new lightweight environmental protection and energy-saving decorative materials, high-grade wall skirting lines, door lines, high-grade stone and ceramic tiles, indoor prefabricated walls, stair board installation, cabinet and bathroom cabinet installation, etc. Where chemical connections work better and are more efficient. The use of nail-free glue instead of traditional nails can not only achieve an aesthetic effect, but also effectively avoid noise and dust pollution, and reduce damage to the struct...
