Problems solved by technology

[0004] Although the existing nail-free adhesives can meet the mandatory regulations of the national standard GB18583 "Limits of Hazardous Substances in Adhesives for Interior Decoration Materials", these adhesives still contain toxic, harmful or low-toxic solvents, and the total solvent content is more than 10%. , and some even reach 50%, the existence of these solvents is not negligible to the harm of people's health and the environment

Abstract

The invention discloses environment-friendly nail-free glue and a preparation method of the environment-friendly nail-free glue. The environment-friendly nail-free glue comprises, by weight, 10-50 parts of silane-modified polyether polymers, 5-30 parts of plasticizer, 5-10 parts of methyl MQ silicon resin, 3-10 parts of white carbon black, 0-8 parts of thixotropic agents, 24-60 parts of reinforcing filler, 0.5-4 parts of dewatering agents and 0.2-3 parts of catalysts. The environment-friendly nail-free glue is good in comprehensive performance, high in construction efficiency, free of solvent, environmentally friendly and capable of replacing traditional iron nails to achieve a good bonding and fixing effect, and has very broad application prospect along with enhancement of the safety and environmental protection sense of people.

Description

technical field [0001] The invention relates to an adhesive, in particular to an environment-friendly nail-free glue and a preparation method thereof. Background technique [0002] Nail-free glue, also known as liquid nails, is a multifunctional decorative adhesive, mainly used for bonding and fixing various wood lines, door casing lines, plaster lines, floor tiles, various decorative pendants and various wallboard projects. In recent years, nail-free glue has gradually replaced the previous fixing methods such as nailing and drilling used in indoor and outdoor decoration, effectively avoiding noise and dust pollution, and also reducing damage to the structure of the house, and has been more and more widely used. [0003] Most of the existing nail-free adhesives use solvent-based neoprene rubber, solvent-based SBS rubber, solvent-based styrene rubber, etc. as adhesive materials, and solvents are inevitably used. For example, the prior art discloses: a kind of nail-free glue...
