Abstract
The utility model discloses a wood -plastic board, including a plastic film layer, first viscose layer, wood chip, second viscose layer and the 2nd plastic film layer that sets gradually. The utility model discloses a wood -plastic board is because the wood chip two sides is all covered by plastic film, and the wood chip two sides is all isolated with the air, and the moisture movement in the air can not cause the change that the size is too big of wood chip. Moisture in the wood chip also can not followed upper and lower two sides because of the temperature variation and volatilized, so the size changes along with the change of temperature hardly. Because plastic film is in the same place with the wood chip bonding for plastic film's size can not have great change along with the change of temperature yet. The wood chip two sides plastic film that all adheres, both sides' performance is complementary, has overcome respective shortcoming, and mould the board to wood -plastic board or pure plank wants the superiority much than pure in stability. This wood -plastic board's comeandgo rate be 0.03% to 0.08% (with BS EN434: 1994 the standard).
Description
Technical field
The utility model is related to sheet material, wood-plastic board more particularly to relatively low rate of expanding with heat and contract with cold and preparation method thereof.
Background technology
The characteristics of there is waterproof and dampproof, zero formaldehyde due to PVC floor, it is deep to be liked by consumer.Due to changes of the PVC to temperature
Change is very sensitive, and the ratio of shrinkage swelling for varying with temperature is very high, limits its use condition.Although people constantly research and develop in recent years,
The ratio of shrinkage swelling that PVC is varied with temperature is reduced for example by adding the raw materials such as plasticizer in PVC, but effect is still paid no attention to
Think.
Common PVC floor is made up of four parts, the bed of material and PVC initial beds in PVC wearing layers, PVC coloured silk films, PVC.This
After hot pressing, cooling shaping, cut becomes PVC floor to four layers of PVC.In this four layers of PVC, with wearing layer, color film and bed material
The ratio of shrinkage swelling highest for varying with temperature of layer.Although can be by reducing which with temperature using tempering process in the raw journey of production
The ratio of shrinkage swelling of degree change, but the PVC board after tempering process expand with heat and contract with cold rate still between 0.25% to 0.35% (with
BS EN 434:1994 standards).
Utility model content
The purpose of this utility model is to provide for a kind of wood-plastic board with relatively low rate of expanding with heat and contract with cold and preparation method thereof, can
To solve one or more in above-mentioned prior art problem.
According to one side of the present utility model, there is provided a kind of wood-plastic board, including the first plastic sheeting for setting gradually
Layer, the first adhesive-layer, wood chip, the second adhesive-layer and the second plastic film layers.
Change of the plastic sheeting to temperature is very sensitive, and the change of temperature can cause which to expand with heat and contract with cold, and moisture in air contains
The change of amount is not affect on plastic sheeting.The change of humidity in the change of environment temperature or air causes the moisture in wood chip
Volatilization absorbs, so as to cause the change in size of wood chip.
Wood-plastic board of the present utility model as wood chip two sides is all by covered rearing with plastic film, wood chip two sides all with air exclusion,
Moisture change in air does not result in the change too greatly of the size of wood chip.Moisture in wood chip also will not because of temperature change from
Upper and lower surface volatilize or absorb, so the size of wood chip hardly variation with temperature and change.Due to plastic sheeting and wood chip
Be bonded together so that the size of plastic sheeting also will not variation with temperature and have a greater change.Wood chip two sides all bonds
Plastic sheeting, the performance complement of both sides overcome respective shortcoming, thus wood-plastic board in stability than pure mould plate or pure plank
It is more advantageous.The rate of expanding with heat and contract with cold of the wood-plastic board is 0.03% to 0.08% (with BS EN 434:1994 standards).
Additionally, if using transparent plastic sheeting, the wood-plastic board can obtain the sheet material with natural wood veins pattern, and
It is not the grain pattern of printing, pattern is true to nature, the appreciative value of wood-plastic board can be greatly improved.
In some embodiments, the thickness of wood chip of the present utility model is 0.05～0.5mm.If wood chip is too thick, wood
The area that piece section is exposed is big, can accelerate the absorption of moisture or distribute, and affects the stability of wood-plastic board.If wood chip is too thin,
Difficulty of processing is than larger.
In some embodiments, the thickness of the first plastic film layers of the present utility model or the second plastic film layers is
0.05～0.7mm.Plastic sheeting is thicker, and its rate of expanding with heat and contract with cold is higher.To improve the stability of wood-plastic board, preferably using relatively thin modeling
Material film.
In some embodiments, the utility model also includes being sequentially arranged in the first plastic film layers or the second plastic sheeting
The bed of material and PVC initial beds in the PVC of layer lateral surface.Plus the bed of material in PVC and PVC initial beds, the hardness of wood-plastic board can be increased.
In some embodiments, the utility model is also included outside the first plastic film layers or the second plastic film layers
The calcium-plastic board of side.Calcium-plastic board is increased, the sound insulation of wood-plastic board, heat-insulated and humidity resistance can be made more preferable.
In some embodiments, the utility model includes multigroup the first plastic film layers for setting gradually, the first viscose glue
Layer, wood chip, the second adhesive-layer and the second plastic film layers, the first adhesive-layer and the second adhesive-layer are PUR.This wood-plastic board
Can both there is enough thickness, it is possibility to have lower rate of expanding with heat and contract with cold.
