Embodiment 1

[0021] First take 10kg of polyvinyl alcohol (model 2099) and 100kg of water and add them to the reaction kettle at the same time, heat up under constant stirring, cool to 50-60°C after it dissolves completely, add emulsifier OP-104kg, dodecane 2 kilograms of sodium phenylsulfate; under stirring, it is added successively to make a total amount of 20-40% ammonium persulfate aqueous solution of 0.5 kilograms, and then adding a mixed total amount of 10-20% vinyl acetate ( 43 kg) and fumaric anhydride (2 kg), the temperature rose to 80°C under constant stirring; Complete in 2-4 hours; heat up to 90°C and keep for one hour, add 6 kg of kaolin after cooling down to 70-80°C, stir evenly and keep for 20 minutes, cool to 30°C, and pack out the material, that is, the finished product of one-component adhesive is about 167 kg (due to the volatilization of a small amount of water).

[0022] Performance:

[0023] 1. Appearance: milky white. Uniform and fine viscous glue.

[0024] 2. Sol...

Embodiment 2

[0034] Take 14 kg of polyvinyl alcohol (model 2099), 100 kg of water, 4.5 kg of emulsifier OP-10, 2 kg of sodium dodecylbenzenesulfonate, and 0.5 kg of potassium persulfate aqueous solution (dissolve potassium persulfate in water first) , 42 kilograms of methyl methacrylate, 3 kilograms of methacrylic acid, and 6 kilograms of bentonite; finally produce about 172 kilograms of one-component adhesive finished products (due to the volatilization of a small amount of water).

[0035] Its preparation method is the same as that of Example 1, so it is omitted.

Embodiment 3

[0037] Take 9 kilograms of polyvinyl alcohol (model 2099), 100 kilograms of water, 3 kilograms of emulsifier OP-103, 3 kilograms of sodium dodecylbenzene sulfate, and 0.7 kilograms of sodium persulfate aqueous solution (dissolve sodium persulfate in water first), 38 kilograms of butyl methacrylate, 3 kilograms of maleic anhydride, and 5 kilograms of light calcium carbonate; finally produce about 163 kilograms of single-component adhesive finished products (due to the volatilization of a small amount of water).

[0038] Its preparation method is the same as that of Example 1, so it is omitted.

Abstract

The invention relates to an environment-friendly adhesive and a preparation method thereof. The main point of the technology is that a certain amount of polyvinyl alcohol and water are added in a reaction vessel to be continuously stirred to lead the temperature to be increased; after the mixture is fully dissolved and cooled, a certain amount of emulsifier OP-10 and dodecyl benzene sodium sulfate are added into the obtained material and stirred, then added with proper amount of persulphate water solution and prepared alkenyl unsaturated acid ester and alkeneyl unsaturated anhydride or acid mixture; after the temperature is increased to 80 DEG C, the rest alkenyl unsaturated acid ester and alkeneyl unsaturated anhydride or acid mixture are added, then evenly added with the rest persulphate water solution; after 2-4 hours, the obtained material is added with addictive, stirred and cooled to 30 DEG C, and the final product of the environment-friendly adhesive is obtained. The invention is applied to furniture, advanced glued boards, decoration boards and other wooden products and has the performances of little smell, easy brushing, large beginning stickiness, wearing resistance and proper viscosity. The wooden product of glued joint has no evident glue line, has good waterproof property and can be used without cracking for a long time.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a water-soluble environment-friendly adhesive and a preparation method thereof. It is mainly used for bonding woodworking furniture, various wood-based panels, glulam processing, advanced solid wood composite floor bonding, decoration and many other aspects, and has a wide range of applications. Background technique [0002] As we all know, most of the glue used in the domestic woodworking industry currently uses urea-formaldehyde glue, phenolic glue, melamine-formaldehyde glue and polyvinyl acetate glue. Poisonous, pollutes the environment, has hot eyes and pungent smell. Polyvinyl acetate glue, also known as white latex, is a white viscous liquid prepared by emulsion polymerization of vinyl acetate monomer with peroxide as an initiator. It is widely used in the bonding of wood processing, wood-based panels, paper, textiles, leather and other industries. It is a widely used ...
