Problems solved by technology

[0005] In order to overcome the defects of slow curing speed, easy defects in the glue film and weak bonding caused by the single-sided coating of a single type of cold glue for the bonding of the plastic surface and the wood layer in the prior art, the present invention provides a A composite profile coated with veneer on the surface of a plastic / wood-plastic profile and a manufacturing method, which greatly improves the bonding force between the veneer and the surface of the plastic / wood-plastic profile, and the quality of the film is good, so that the plastic / wood-plastic profile and the veneer strong bond between

Embodiment 1

[0030] (1) Decontamination and dust removal treatment is performed on the ABS (acrylonitrile-styrene-butadiene copolymer) profiles, that is, the dust attached to the surface of the profile to be coated is sucked out through the suction device, which is beneficial to the surface of the profile and the veneer in the subsequent process the gluing;

[0031] (2) The main component is the interface affinity agent of polycondensation resin and chlorinated hydrocarbon to the coating surface to be coated of the ABS profile after dedusting;

[0032] (3) While performing steps (1) and (2), apply PUR hot-melt adhesive to the inner surface of the veneer with a thickness of 0.15 mm. The melting temperature of PUR hot-melt adhesive is 110 ° C, and its coating temperature is 120 ° C. ℃, glue amount is 90g / m 2 ;

[0033] (4) to the ABS profiles processed through steps (1) and (2) and the wood veneer processed through step (3), roll-press coating by the cladding machine with molding rollers, ...

Embodiment 2

[0035] The difference between this embodiment and Embodiment 1 is that a non-woven fabric layer is added to the inner surface of the veneer, and correspondingly, the glue-coating treatment on the inner surface of the veneer is carried out on the non-woven fabric layer. In addition, the ABS composite profiles coated with veneer that have been processed through steps (1) to (4) are also subjected to sawing treatment, and the sawing treatment uses a sawing machine to make its periphery neat, and the length and / or width meet the following requirements: storage and transport requirements.

Embodiment 3

[0037] The difference between this embodiment and Example 2 is that the ABS composite profile covered with wood veneer will also undergo a health preservation stage before leaving the factory. 12 hours.

[0038]In addition, the standing time of the health preservation stage can also be 24 hours, 36 hours, 48 ​​hours, etc. Generally, it depends on the amount of PUR hot melt adhesive applied, so that it can fully react with the moisture in the air, and it can be finished after the reaction is completed. After the health-preserving stage is over, generally, the resting time is 6-48 hours.

Abstract

The invention provides a composite sectional material covering bark on the surface of a plastic/wood plastic sectional material and a manufacture method thereof, in order to overcome the defects of slow solidification speed, easy defect generation of glue films and unstable bonding caused by the mode of applying single cold glue to single side for bonding a plastic surface and a wood layer in the prior art. The method comprises the following steps: A. carrying out stain and dust removal treatment to the surface to be covered of the plastic/wood plastic sectional material; B. applying hot melt adhesive to the inner surface of the bark, and applying interface affine agent to the surface to be covered of the plastic/wood plastic sectional material which is subjected to the step A; and C. rolling and covering the bark on the surface of the plastic/wood plastic sectional material through a forming roll of a covering machine, so that the inner surface of the bark and the surface to be covered of the plastic/wood plastic sectional material can be bonded together. With the manufacture method, the bonding power between the surface of the bark and the surface of the plastic/wood plastic sectional material can be greatly improved, and the glue film has excellent quality, so that the plastic/wood plastic sectional material and the bark can be firmly bonded.

Description

technical field [0001] The invention relates to a composite section bar and a manufacturing method thereof, in particular to a composite section bar coated with veneer on the surface of a plastic / wood-plastic section bar and a manufacturing method thereof. Background technique [0002] With the development of the plastic industry and the maturity of manufacturing technology, plastic profiles and wood-plastic profiles are more and more widely used by people. For example, plastic / wood-plastic doors and windows, plastic / wood-plastic moldings on furniture and decorative objects, plastic / wood-plastic moldings on room walls, etc. However, the surface smoothness of plastic / wood-plastic profiles is not enough, and the texture and color cannot fully meet the decorative requirements. Although the profiles using pure solid wood have good decorative effects, they are expensive, easy to deform, crack, and have large color differences, and they should not be widely used for a long time f...
