Problems solved by technology

[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, etc., It will be degummed and affect its use effect

Embodiment Construction

[0012] The present invention will be further described below in conjunction with the examples, but not as a basis for limiting the present invention.

[0013] The adhesive for wood boards of the present embodiment, the adhesive raw material comprises the following components by weight: 0-500 parts of epoxy resin, 1-200 parts of paraffin emulsion, 1-300 parts of white latex, 1-200 parts of curing agent 50-100 parts of superfine cellulose powder, 0-10 parts of cellulase;

[0014] The adhesive is prepared by dissolving the above-mentioned raw materials in an organic solvent to form a jelly.

[0015] Preferably, the adhesive raw material comprises the following components by weight: 400 parts of epoxy resin, 200 parts of paraffin emulsion, 300 parts of white latex, 200 parts of curing agent, 80 parts of superfine cellulose powder, 5 parts of cellulase .

[0016] In this embodiment, the curing agent is one or a mixture of two or more of methyl hexahydrophthalic anhydride, dicyand...

Abstract

The invention discloses a binder for a wood plate. The binder is prepared from 0 to 500 parts by weight of epoxy resin, 1 to 200 parts by weight of a paraffin emulsion, 1 to 300 parts by weight of white latex, 1 to 200 parts by weight of a curing agent, 50 to 100 parts by weight of ultra-fine cellulose powder and 0 to 10 parts by weight of cellulase. The binder is prepared from the above raw materials dissolved in an organic solvent and is jelly. Through synergetic bonding of epoxy resin and white latex, bonding strength is improved so that the binder does not easily fall off in long-term use. The paraffin emulsion is used and the paraffin emulsion with fine particle sizes can naturally penetrate into a wood plate so that the wood plate has water resistance after drying. The cellulose has good absorptivity, has hydrophily under cellulase action and realizes moisture prevention.

Description

technical field [0001] The invention relates to the field of adhesives, in particular to an adhesive for wood boards. 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 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, etc., It will be degummed and affect its use effect. [0003] Therefore, it is necessary to improve the adhesive for wood boards, which not only improves its bonding strength, prevents degumming, but also makes it have better water resistance to achieve a waterproof effect. Contents of the invention [0004] In view of this, the present invention provides an adhesive for wood boards, which improves its bonding strength, prevents degumming, and makes it have better water resistance to achieve a waterproof effect. [0005] Adhesive for woo...
