Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a laminate of WPC veneer and a wood substrate and a method for manufacturing the same, and more particularly, a laminate of WPC veneer and a wood board and a method for manufacturing the same, and more specifically, a laminate of WPC veneer and a wood board injected with a mixture of a thermosetting resin and a thermoplastic composite. The present invention relates to a laminate of resin substrates molded from a plastic synthetic resin and a method for manufacturing the same.

In general, WPC veneers are made by injecting thermosetting synthetic resins such as polyester vs. Many are offered on the market for these reasons. If it is necessary to laminate this WPC veneer to a resin substrate, the two must be bonded together using an adhesive. Therefore, in practice, in order to bond a thin WPC veneer to a resin substrate, an adhesive had to be applied onto the resin substrate. However,
When bonding this thin WPC veneer to a resin substrate that is under heating immediately after extrusion, the adhesive cannot be applied to the resin substrate because the wood substrate is hot and still in a soft state. Therefore, it is virtually impossible to bond a thin WPC unit to a resin substrate immediately after extrusion using an adhesive.The present invention has been made in view of the above points, and the first The purpose is to provide a laminate in which WPC veneers are bonded to resin substrates without using adhesives, and the second purpose is to provide a laminate in which WPC veneers are bonded to resin substrates without using adhesives. It is an object of the present invention to provide a method for manufacturing a laminate that can be bonded to a +M resin substrate without using a separate adhesive.

The present invention will be explained in detail based on the embodiments shown in the figures below.
The surface of the laminate of WPC veneer and resin substrate (~ is wood veneer f1 injected with a mixture of thermosetting synthetic resin and thermoplastic synthetic resin) according to The WP according to the present invention is characterized in that a synthetic tree tli and a resin substrate (2) molded from a thermoplastic synthetic resin having heat-fusibility are bonded together by heat-sealing the two.
The method for producing a laminate of C veneer and resin substrate is to heat a wooden board (1) injected with a mixture of thermosetting synthetic resin, thermoplastic synthetic resin + M resin, under heating immediately after extrusion molding. A wooden veneer (
1) by melting the thermoplastic synthetic resin in the wood veneer (1).
) and No. 11 resin substrate (2) are bonded together by heat fusion between the two thermoplastic synthetic resins, and the wood veneer is a softwood veneer such as American Tozuki. The thickness is Q, and the one after 5 M1471 is used. The mixture to be injected into this wood veneer is a mixture of thermosetting synthetic resins, unsaturated +0 polyester + LI-styrene, and thermoplastic synthetic resin, vinyl chloride ILI, with a degree of polymerization of about 100 to 91) 0. The 1st grade vinyl is mixed with the polyester at a ratio of 2o/- (by weight), and the mixture described in 1) is poured into the wood li board (1) under reduced pressure. 5. Also, in order to incorporate unsaturated vinyl chloride into the styrene system, +1jnia and MEK1ξ:+M vinyl IL- are mixed into Schiff[], and then this completely unsaturated polyester is added.・−Styrene group'(
4 people do it. On the other hand, n Pilgrimage board (2) and +, -C are heat 1lI
A polyvinyl chloride foam that has been melted with plastic synthetic resin 1 is used, and the thermosetting resin that has already been cured is placed on the soft f# resin substrate (2) L at a high temperature immediately after being extruded by an extruder 13). A wooden veneer injected with a mixture of synthetic resin and thermoplastic synthetic resin (2) is supplied, and the thermoplastic synthetic resin in the wooden veneer 11+ is melted by the high temperature of the tree substrate (2).
While passing through the pressurized O-ru F4H41, the thermoplastic synthetic resins of the wood veneer (1) and resin board (2) undergo thermal fusion, resulting in the wood veneer (1) and resin board (2). This is why they are glued together. That is, the temperature of the resin substrate 1'tl t is approximately 180°C immediately after extrusion, and the temperature is 150°C, 160°C,
The wood veneer (1) is supplied onto the resin substrate (2) when the temperature has dropped to 150゛().
When heated to a certain degree, the internal thermoplastic resin (dichloride 11
/) is melted, and this is the uncured wood substrate (2).
) and the pressure 0-L141 help to thermally fuse them. In addition, the thermoplastic resin injected into the wood veneer 111 includes the thermoplastic synthetic resin 8i and the resin substrate (2).
Any material that can be fused may be used as long as the resin substrate (2) is made of polychlorinated resin, and in addition to the above-mentioned polychlorinated resin, for example, AXOSI resin may be used.

As described below, the present invention provides heat curing in a mixture of a PA hardening mature tree and a thermoplastic synthetic resin that is injected into a wood veneer.
The iT plastic synthetic resin is melted by the heat of the wood veneer board on which the wood veneer is laminated, and the wood veneer and the beak 11 board are bonded together. It can be bonded by fusion bonding, and without using a separate adhesive, the synthetic injected wood veneer can be attached to the substrate (with the advantage of using no adhesive). It is difficult to apply, and after extrusion molding with a thin wood veneer, it is easy to bond the wood veneer to the base. The reinforced thermosetting synthetic resin and high surface hardness make the product highly wear resistant.
