Abstract

The invention discloses high-bonding-strength plate splicing glue and a preparation method thereof. The high-bonding-strength plate splicing glue comprises, by weight, 120-300 parts of vinyl acetate, 60-150 parts of vinyl versatate, 30-120 parts of butyl acrylate, 5-20 parts of acrylic acid, 400-500 parts of deionized water, 50-150 parts of non-phthalate plasticizer, 15-100 parts of polyvinyl alcohol, 2-8 parts of silane coupling agent, 3-5 parts of anionic emulsifier, 3-12 parts of nonionic emulsifier and 1-3 parts of defoamer. The high-bonding-strength plate splicing glue has bonding strength that other binders do not have and is high in adhesiveness and stability, convenient to use and wide in application range. In addition, the high-bonding-strength plate splicing glue has the advantages of being nontoxic, free of peculiar smell, pollution and corrosion, burning-free and free of drawing during coating.

Description

technical field [0001] The invention relates to the field of panel glue, in particular to a panel glue with high bonding strength and a preparation method thereof. Background technique [0002] What we usually call a jigsaw glue is a kind of adhesive commonly used in the decoration and solid wood board industry. It is named for its wide bonding range and convenient use. The main components of early puzzle glue are neoprene, bone glue, kraft glue, polyurethane, etc. Generally, toluene, xylene, methylene chloride, and chloroform are used as solvents. Because these substances are harmful to the body, their use has been banned abroad, but China has withdrawn from the decoration and solid wood board industry market. [0003] With the GB18583-2008 mandatory standard promulgated by the country, the adhesives used for interior decoration that use benzene as a solvent have been banned, and strict limits have been set for toluene and total volatile organic compounds. In order to mee...
