Problems solved by technology

[0006] The above process solves the problem that the non-woven fabric is rolled into the glue machine when sizing, but when the non-woven fabric is rolled after sizing, the adhesive will be cured, so that the non-woven fabric is bonded to each other, and cannot be unfolded and cut into sheets again. , cannot enter the next process

Embodiment 1

[0022] An adhesive used to manufacture flexible decorative veneers, which is uniformly mixed with urine glue, white glue, flour, lignin, and cationic surfactants. Since the adhesive is easily affected by environmental temperature changes, the bonding strength is therefore, in In actual use, the adhesive ratio should be adjusted according to seasonal changes. For example: in summer, the temperature is higher, and the adhesive cures faster. The mass ratio is: urine glue: white glue: flour: lignin: cationic surfactant = 100:40:5:5:0.1; while the temperature in winter is lower , the adhesive solidifies slowly, and the mass ratio is: urine glue: white glue: flour: lignin: cationic surfactant=100:60:15:15:0.5. The cationic surfactant is dodecyl trimethyl ammonium chloride or cetyl dimethyl benzyl ammonium chloride.

Embodiment 2

[0024] Use the adhesive described in the embodiment of the present invention 1 to manufacture the operation of flexible decorative veneer as follows:

[0025] a. Veneer finishing: first classify and sort the decorative veneer;

[0026] b. Glue adjustment: mix urine glue, white glue, flour, lignin, and cationic surfactant according to the mass ratio, and stir for 10 to 20 minutes;

[0027] c. Sizing: Roller sizing of non-woven fabrics, the amount of sizing is controlled at 30-50g / m 2 ;

[0028] d. Roll: roll the non-woven fabric that has been glued into a roll for easy cutting;

[0029] e. Cutting: Cut the non-woven fabric of the roll into the required length specification;

[0030] f. Pavement combination: combine the cut non-woven fabric and decorative veneer pavement into a slab;

[0031] g, hot pressing: the above-mentioned slab is sent into a hot press for hot pressing to obtain a semi-finished product;

[0032] h. Edge cutting and grading and packaging: Cut the above...

Abstract

The invention belongs to the field of wood processing industries, and particularly relates to an adhesive for manufacturing a flexible decoration veneer. The adhesive for manufacturing the flexible decoration veneer is formed by uniformly mixing urea glue, white glue, flour, lignin and cationic surface active agents, and the weight ratio of urea glue to white glue to flour to lignin to cationic surface active agents is 100:(40-60):(5-15):(5-15):(0.1-0.5). The adhesive disclosed by the invention has the characteristics of fast surface dry, high adhesive strength and difficulty in adhesive permeation, solves the problem that glued non-woven fabrics are easily adhered mutually during drum winding in a manufacturing process of the flexible decoration veneer, and also solves the problem of adhesive permeation so as to ensure the beauty of the flexible decoration veneer.

Description

technical field [0001] The invention belongs to the wood processing industry, in particular to an adhesive used for manufacturing flexible decorative veneer. Background technique [0002] General natural veneer or recombined decorative veneer, especially thin veneer is brittle, not flexible enough, and easy to crack, so it is not suitable for the decoration of special-shaped structural surfaces. Flexible decorative veneer is a reelable and flexible decorative veneer that is laminated with non-woven fabric or kraft paper and other reinforcing materials on the back of natural veneer or recombined decorative veneer. This not only enhances the flexibility of the recombined decorative veneer, but also increases the overall thickness of the product, saving wood resources. The veneer can be used for decorative veneering of various special-shaped curved surfaces, and is also suitable for veneering of bas-relief surfaces, which broadens the application range of traditional veneer. ...
