Abstract

The invention discloses a low-cost environment-friendly water glass wood adhesive which comprises components of 100 parts of water glass with the mass percentage of 30-60%, 10-30 parts of a water-soluble polymer, 90-270 parts of deionized water, 10-50 parts of a high polymer emulsion, 1-5 parts of advanced fatty acid salt and 2-10 parts of an inorganic solidifying agent. Simultaneously, the invention further discloses a preparation method of the water glass wood adhesive. The preparation method includes heating the deionized water, slowly adding the deionized water to the water-soluble polymer, stirring the mixture to obtain a solution, adding the water glass to the solution, evenly stirring the solution to perform an aging reaction, adding the high polymer emulsion and the advanced fatty acid salt after the aging, and preserving heat after stirring at the temperature of 40-80 DEG C; and then cooling the mixture to the temperature of 30-60 DEG C, adding the inorganic solidifying agent, and evenly mixing the mixture to obtain the low-cost environment-friendly water glass wood adhesive. The water glass wood adhesive is stable in performance, simple and easy in preparation process and widely applicable to industrialization production.

Description

technical field

[0001] The invention relates to a wood adhesive, in particular to a low-cost environmental-friendly water glass wood adhesive with strong adhesive force and good water resistance and a preparation method thereof. Background technique

[0002] In the existing environmental protection decoration industry, with the increasing awareness of environmental protection and the strict restrictions on the content of aldehyde toxic compounds and other volatile organic compounds in adhesives in various countries around the world, wood adhesives are gradually getting rid of the use of urea-formaldehyde resins. Traditional aldehyde adhesives dominated by phenolic resins, phenolic resins and melamine-formaldehyde resins are developing rapidly in the direction of water-based, low-pollution, and environmentally friendly adhesives. The development of environmentally friendly high-performance adhesives has become a research hotspot in the field of wood adhesives.
