Problems solved by technology

But the patent application number is the invention patent application of CN200410014197.0, there are some shortcomings that are difficult to overcome with its method to prepare wood core melamine veneer: the one, do not carry out softening treatment to substrate, for hard, brittle and fragile and bending After the substrate is laminated with melamine by its method, the product produced has a low degree of compaction, the melamine laminate is easy to fall off, the product is brittle and easily broken, and the product is also very easy to bend and deform; When the impregnated paper is laminated, the substrate will be displaced on the mold plane of the hot press, which will cause the problem of uneven thickness and fragmentation of the product; the third is to heat press the melamine impregnated paper under the condition that the temperature of the upper and lower templates of the laminating hot press is the same. veneer, the water vapor generated will easily cause the melamine veneer paper to blister

Embodiment 1

[0018] As shown in the figure, a hot pressing concave-convex forming process for melamine decorative veneer includes the following steps:

[0019] A. Mix the softening agent and water to make a softening liquid, spray the softening liquid on both sides of the melamine veneer substrate until both sides are wetted, and fully soften the melamine veneer substrate, which is resistant to hard, brittle, curved, and easily broken The substrate is softened and modified, so that the fiber of the substrate wood has good flexibility and lubricating permeability;

[0020] B. After the formed substrate is cooled, the veneer paper impregnated with melamine resin solution is laid on the substrate on the front of the substrate, and placed on the molding die for molding. The molding die includes an upper template 1 and a lower template 3, on the upper template There is a convex plate 2 and a groove 4 on the lower template 3. Place the substrate with the melamine veneer on the lower template 3 of the...

Embodiment 2

[0025] A hot pressing concave-convex forming process for melamine decorative veneer, which includes the following steps:

[0026] A. Mix the softener and water to make a softening liquid, spray the softening liquid on both sides of the melamine veneer substrate until both sides get wet to fully soften the melamine veneer substrate;

[0027] B. Lay the melamine veneer coated with melamine resin glue on both sides on the substrate, and place it on the molding die for molding. The molding die includes an upper template 1 and a lower template 3. The upper template 1 has a convex plate 2 and the lower template 3 There is a groove 4, the substrate with the melamine veneer is placed on the lower template 3 of the molding die, the upper template 1 is settled and pressed, the convex plate 2 on the upper template 1 and the groove 4 on the lower template 3 are closed and fully compressed. The substrate on which the melamine decorative veneer is pasted forms a concave-convex shape under the ac...

Embodiment 3

[0032] A hot pressing concave-convex forming process for melamine decorative veneer, which includes the following steps:

[0033] A. Mix the softener and water to make a softening liquid, spray the softening liquid on both sides of the melamine veneer substrate until both sides get wet to fully soften the melamine veneer substrate;

[0034] B. Lay the melamine veneer coated with melamine resin glue on both sides on the substrate, and place it on the molding die for molding. The molding die includes an upper template 1 and a lower template 3. The upper template 1 has a convex plate 2 and the lower template 3 There is a groove 4, the substrate with the melamine veneer is placed on the lower template 3 of the molding die, the upper template 1 is settled and pressed, the convex plate 2 on the upper template 1 and the groove 4 on the lower template 3 are closed and fully compressed. The substrate on which the melamine decorative veneer is pasted forms a concave-convex shape under the ac...

Abstract

The invention provides a melamine decorative veneer hot-pressing concavo-convex forming process. By the process, the problems that compaction degree of the product produced by the process is low, the melamine decorative veneer is easy to drop off, the product is fragile and is susceptible to bending deformation, a base plate generates displacement, and the melamine decorative veneer is bubbled easily caused by water vapor are solved. The process comprises the following steps of: softening the base plate; paving the melamine decorative veneer with double surfaces coated with melamine resin glue on the base plate; placing the base plate on a mould-pressing mould to perform mould pressing, wherein the mould-pressing mould comprises an upper template and a lower template, a convex plate is arranged on the upper template, and a groove is formed on the lower template; placing the base plate, where the melamine decorative veneer is paved, on the lower template of the mould-pressing mould; and settling the upper template to press until the convex plate on the upper template and the groove on the lower template are closed and pressed, so that the base plate with the melamine decorative veneer forms a concavo-convex shape under the action of the convex plate and the groove.

Description

Technical field [0001] The invention relates to a forming process for decorative veneer of sheet material, in particular to a process for hot pressing concave-convex forming of decorative veneer of melamine. Background technique [0002] In recent years, there are many varieties of decorative boards. The most commonly used ones are blockboard, density board, and melamine board. They are the main products in the current decorative and decorating market. Melamine boards have good fire resistance and moisture resistance, but melamine boards are very It is difficult to press into concave and convex shapes and patterns, which affects the actual use of door panels in decoration. Therefore, many companies are studying composite panel technology, and the medium and high density panel core melamine laminate panels are better used. The patent number is 02274169.0, and the invention name is a utility model patent of a melamine blockboard. The utility model patent discloses a melamine blockb...
