Embodiment Construction
[0015] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0016] Such as figure 1 The foam insulation wood-plastic board shown is composed of three layers, the top layer is a decorative layer 1, the foam insulation wood-plastic layer 2 is bonded under the decoration layer 1, and the waterproof and moisture-proof layer 3 is bonded under the foam insulation wood-plastic layer 2.
[0017] The decorative layer 1 is adhered to the foam insulation wood-plastic layer 2 by a hot press under the condition of 90°.
[0018] The foam insulation wood-plastic layer 2 and the waterproof and moisture-proof layer 3 are bonded together under the conditions of 120° and 20MPa.
[0019] The foam insulation wood-plastic layer 2 includes polystyrene, wood fiber, foaming agent, binder, and plasticizer.
[0020] The wood fiber includes at least one of wood fiber and bamboo fiber.
[0021] The foam insulation wood-plastic layer 2 ...

Abstract
The invention provides a foam heat-preservation wood plastic composite board, and belongs to the technical filed of heat-preservation decorative boards. The foam heat-preservation wood plastic composite board is formed by three layers, wherein the uppermost layer is a decorative layer, a foam heat-preservation wood plastic composite layer is arranged below the decorative layer in a bonding mode, and a waterproof damp-proof layer is arranged below the foam heat-preservation wood plastic composite layer in a bonding mode. The foam heat-preservation wood plastic composite layer comprises polyvinyl benzene, wood fiber, foaming agents, bonders and plasticizers. The foam heat-preservation wood plastic composite board is simple in structure, heat-preservation properties of polyvinyl benzene foam plastics are used, reinforcing and beautiful properties of the wood fiber are added, the foam heat-preservation wood plastic composite board plays a role in beautifying the environment even if the decorative layer is not bonded on the outer surface, and cheap plastics is used as the bottommost layer to achieve waterproof and damp-proof effects; meanwhile, when the foam heat-preservation wood plastic composite board is dismounted, cost is not high in case that the bottommost layer is damaged.
Description
technical field [0001] The invention relates to a foam thermal insulation wood-plastic board, which belongs to the technical field of thermal insulation decorative boards. Background technique [0002] Expanded polystyrene (EPS) has the advantages of low density, high specific strength, low water absorption, acid and alkali resistance, good heat and sound insulation, good thermal insulation, shockproof, decorative, easy to form, and excellent cost performance, making it It has been developed rapidly. In addition to being widely used in cushioning packaging, food preservation packaging, interior and exterior wall insulation, heat insulation, etc., it has also become more and more eye-catching in the construction and industrial fields in recent years. The outstanding contribution of EPS in architectural applications lies in its thermal insulation and thermal insulation properties. Its extensive use in buildings can effectively reduce the use of air conditioning and heating ene...
