Problems solved by technology

However, its kaolin and talc generally only reach the μm level, and CaCO 3 Although it can reach the nm level, it will form colloids when it encounters water during the high-speed water dispersion process, which will cause particle agglomeration and deteriorate the performance of the panel adhesive.
[0006] Compared with "trialdehyde glue", the main agent of the above-mentioned panel glue does not contain formaldehyde, which is better in environmental protection, but the comprehensive performance of product production and application needs to be further improved, such as the particle type of inorganic filler is single, and the solvent-based monomer is poisonous , flammable, odor, easy to cause air and environmental pollution and other shortcomings, you can use bio-based monomers that are rich in resources, cheap and non-toxic, and enhance the effect of cross-linking agents, increase the use of thixotropic agents, and reduce the risk of original particle agglomeration Shortcomings, a new type of rubber that enhances the mechanical properties of the adhesive

Abstract

The invention relates to a water-based environment-friendly plate splicing adhesive and a preparation method thereof, belonging to the technical field of adhesives. The water-based environment-friendly plate splicing adhesive comprises the following raw materials in parts by mass: 0.1-1 part of polyvinyl alcohol, 0.5-10 parts of polyvinyl acetate emulsion, 0.5-10 parts of polyvinyl acetate-ethylene emulsion, 0.5-2 parts of calcium carbonate powder, 0.01-0.1 part of nano oxide, 0.001-0.02 part of carboxymethyl cellulose, 0.1-1 part of styrene-butadiene latex, 0.01-0.1 part of defoaming agent, 0.01-0.08 part of preservative, 6-12 parts of water and 1.34-3.46 parts of crosslinking agent. The polyvinyl acetate emulsion and polyvinyl acetate-ethylene emulsion are used as the base, and the prepared main agent is free of formaldehyde, and thus, is a water-based environment-friendly adhesive. All the monomers and components belong to low-toxicity environment-friendly chemicals which are beneficial to clean production.

Description

technical field [0001] The invention belongs to the technical field of adhesives, and in particular relates to a water-based environment-friendly jigsaw glue and a preparation method thereof. Background technique [0002] Glulam can be spliced ​​by making full use of short and small materials or small-diameter materials. It not only retains the characteristics of excellent performance and uniform material of natural wood, but also can be spliced ​​into large-size panels that cannot be replaced by wood-based panels, which greatly improves the utilization of wood. It is generally welcomed in domestic and international markets. Due to the protection of the ecological environment and forest resources in my country, the available forest and timber resources have decreased sharply in recent years, and it is particularly important to rationally utilize existing timber resources. [0003] Adhesives for glulam are one of the most important types of glue in the adhesive industry. Co...
