Waterproof anti-aging plate alignment adhesive preparation method

Abstract

The invention belongs to the technical field of adhesive preparation and specifically relates to a waterproof anti-aging plate alignment adhesive preparation method. According to the preparation method disclosed by the invention, lecithin in a soybean extracting solution is utilized as an emulsifying agent, and the lecithin has excellent hydrophobic performance; a hydrophobic layer can be formed on the surface of a latex film, so that water resistance of the latex film is improved; the soybean extracting solution contains a lot of unsaturated fatty acid and can perform esterification with fiber surface hydroxyl, so that compatibility between emulsion and linen fiber is promoted; when fiber is loaded to resin, the flexibility of a plate alignment adhesive film is enhanced, and the plate alignment adhesive film is not prone to brittle rupture. According to the preparation method disclosed by the invention, titanium dioxide is added to whiten the linen fiber; meanwhile, the titanium dioxide can serve as an ultraviolet light absorber, so that the macromolecular plate alignment adhesive is prevented from being damaged; in addition, in a linen fiber oxidizing process, nickel chloride andelhylene diamine tetraacetic acid are chelated, and fluorescence energy radiated to the surface of the plate alignment adhesive can be eliminated by the action among molecules; thus, the waterproof anti-aging plate alignment adhesive preparation method has a wide application prospect.

Description

technical field [0001] The invention belongs to the technical field of adhesive preparation, and in particular relates to a preparation method of water-resistant and anti-aging jigsaw glue. Background technique [0002] With the development of the economy, people's demand for wooden furniture has gradually increased from focusing on the appearance to focusing on the material. However, solid wood cannot be directly used for furniture production, and solid wood sawn timber must be used as solid wood panels for production. 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...

Problems solved by technology

[0006] The technical problem mainly solved by the present invention is aimed at the poor water resistance of the jigsaw glue in the current prior art, and because the glue film formed by the emulsion lacks flexibility, the strength of the bamboo / wood jigsaw after imposition becomes poor under extreme conditions of sunlight exposure, There will be part of the end cracking phenomenon, which will easily lead to the defect of brittle fracture of bamboo / wood panel under the action of external force, and a preparation method of water-resistant and anti-aging panel adhesive is provided
