[0002] At present, most woodworking adhesives use white latex. In actual use, the strength is not enough. After a long time, it is easy to degumming, the adhesive force is not strong, and it is not water-resistant and easy to absorb moisture. If there is water penetration and immersion in furniture, the It will be degummed and affect its use effect

Embodiment 1
[0014] A method for preparing a high-strength woodworking adhesive, which is composed of the following raw materials in parts by weight (kg): smoked sheet glue 3, corn starch 10, modified tree ash 0.5, carboxymethyl cellulose 2, styrene 8, Polyisobutylene 2, sodium tripolyphosphate 2, azodicarbonamide 2, epoxy tetrahydrophthalate dioctyl 3, urea 1, acrylate 2, acrylic acid 3, ammonium persulfate 1, fatty alcohol polyoxyethylene Ether 3, vinegar-acrylic emulsion 3, sodium bicarbonate 1, attapulgite 3, sodium lauryl sulfate 2, water glass 12, polyvinyl alcohol 8, water 150;
[0015] The preparation method of described modified tree ash is:
[0016] (1) Soak tree ash with 12% hydrogen peroxide for 3-4 hours, wash with deionized water, then soak with 10-12% sodium hydroxide solution for 3-4 hours, then wash with deionized water until neutral, and dry;
[0017] (2) Add 2% diethanolamide, 1% nano-carbon, 2% ferrocene, 5% alum powder to the tree ashes, stir at a high speed of 1200-1...

Abstract
The invention discloses a preparing method of high-strength woodworking adhesives. The preparing method comprises, by weight, 3-5 parts of rubber smoked sheets, 8-10 parts of corn starch, 0.5-1 modified wood ash, 1-2 parts of carboxymethy cellulose, 5-8 parts of styrene, 2-3 parts of polyisobutylene, 1-2 parts of sodium tripolyphosphate, 1-2 parts of azobisformamide, 3-4 parts of epoxy four hydrogen phthalate ester, 1-2 parts of urea, 2-3 parts of acrylic ester, 3-5 parts of acrylic acid, 1-2 parts of ammonium persulfate, 2-3 parts of fatty alcohol-polyoxyethylene ether, 3-4 parts of acetic styrene-acrylic emulsion, 1-2 parts of sodium bicarbonate, 3-5 parts of attapulgite, 1-2 parts of sodium lauryl sulfate, 10-12 parts of water glass, 5-8 parts of polyvinyl alcohol, and 120-150 parts of water. According to the preparing method, the ingredient design is reasonable, materials are easy to obtain, a production process is simple, equipment matching is simple, production quality is stable, adhesion force is strong, hardening performance is good, quick drying and no-bubble are achieved, the modified wood ash is added, damage of water molecules to the adhesives is effectively reduced, water resistant performance of the adhesives is greatly improved, due to the fact that hydrophilic performance of the adhesives is reduced, good quick drying performance is achieved, meanwhile adhesion strength is greatly improved, and water resistance is significantly improved.
Description
technical field [0001] The invention mainly relates to an adhesive, in particular to a composite adhesive for woodworking. Background technique [0002] At present, most woodworking adhesives use white latex. In actual use, the strength is not enough. After a long time, it is easy to degumming, the adhesion is not strong, and it is not water-resistant and easy to absorb moisture. If there is water penetration and immersion in furniture, etc. It will be degummed and affect its use effect. Contents of the invention [0003] The object of the present invention is just in order to provide a kind of preparation method of high-strength woodworking adhesive. [0004] The present invention is achieved through the following technical solutions: [0005] A preparation method of a high-strength woodworking adhesive is characterized in that it is composed of the following raw materials in parts by weight: smoked sheet glue 3-5, cornstarch 8-10, modified tree ash 0.5-1, carboxyme...
