Abstract

The invention discloses flame-retardant waterproof silicate wood adhesive and a preparation method thereof. The adhesive comprises the following components in parts by weight: 60 to 70 parts of silicate solution, 10 to 15 parts of carbon nanotube dispersion liquid, 1 to 3 parts of silane coupling agent, 3 to 5 parts of organic silicon emulsion, 5 to 10 parts of vermiculite, 4 to 6 parts of white carbon black and 8 to 12 parts of silicon phosphate. The preparation method comprises the steps of modifying the silicate solution collectively through the carbon nanotube dispersion liquid and organic silicon emulsion and preparing silicate adhesive. The flame-retardant waterproof silicate wood adhesive is environmentally friendly, toxic-free, simple and convenient to prepare and excellent in the performance of the adhesive material.

Description

technical field [0001] The invention relates to the field of wood adhesives, in particular to a flame-retardant and waterproof silicate wood adhesive and a preparation method thereof. Background technique [0002] As we all know, the wood-based panel industry has a huge demand for adhesives. With the increasing awareness of safety and environmental protection in recent years, modern society has higher and higher requirements for adhesives for wood-based panels, mainly in terms of high performance, environmental protection and functionality, and the development of non-toxic and pollution-free high-performance Functional adhesives have become the mainstream trend in the development of wood adhesives. [0003] Silicate adhesives are currently the most important and promising class of inorganic adhesives. It has many advantages such as environmental protection and non-toxicity, easy preparation, low cost, good bonding performance, excellent temperature resistance, room tempera...
