Abstract

The invention discloses a water-based board adhesive and a preparation method thereof. The water-based board adhesive is composed of the following components in parts by mass: 8-10 parts of asbestos powder, 10-12 parts of natural latex, 1-2 parts of formaldehyde, 2-4 parts of polyorganosiloxane, 2-4 parts of sodium sulfite, 3-4 parts of urea, 2-3 parts of sodium hydroxide, 1-2 parts of dicyandiamide, 5-7 parts of polyvinyl alcohol, 2-4 parts of formic acid, 3-5 parts of complexing agent and 1-2 parts of anti-aging agent. The technique is simple, is suitable for mass production and self use for companies, and is low in cost. The water-based board adhesive can effectively resist water, has the advantages of environment friendliness and low formaldehyde release amount, and achieves the CARB2 standard. The adhesive can enhance the lightness and strength of the plywoods when being used for greater-curvature plywoods and light-weight plywoods.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a water sheet glue and a preparation method thereof. Background technique [0002] With the development of industrial society, the usage of industrial boards is gradually increasing. The current environmental protection board is the development trend, and the development of environmental protection glue is unstoppable. The most used on the market is polyvinyl alcohol environmental protection adhesive, polyvinyl alcohol environmental protection adhesive belongs to a new type of non-polluting, quick-drying water-based adhesive production method, applied to the production of wood-based panels can realize the pollution-free cold-pressed production of wood-based panels. Compared with similar adhesives currently on the market, it does not contain toxic components such as formaldehyde (using modified urea-formaldehyde resin or melamine resin or water-soluble phenolic resin that can re...
