Embodiment 1

[0014] First, mix 50kg of polyvinyl chloride and 15kg of active calcium carbonate in the cold bucket of the mixer, then heat it to 80°C, then add 2kg of wood flour and 0.5kg of stearic acid to the heated mixture Calcium, 0.9kg of organic dilute (TM-181), 0.5kg of foaming agent, 3kg of calcium zinc stabilizer (K-400P), 3kg of titanium dioxide (TiO2), 0.3kg of UV agent and 0.5kg of chlorine Polyethylene, and then mixed by a mixer to obtain a mixture of wood-plastic materials, and finally the above-mentioned mixture of wood-plastic materials is heated to 120 ° C and then sent to an extruder for extrusion. The wood powder of the above-mentioned mixed species should be controlled within 20-150 mesh, and the water content in the wood powder should be below 8%.

[0015] At the same time, mix 75kg of polyvinyl chloride and 15kg of active calcium carbonate in the cold barrel of the mixer, then heat it to 80°C, and then add 1kg of organic dilute (TM-181 ), 1.5kg of foaming agent, 8kg o...

Embodiment 2

[0019] The specific operation steps in the second embodiment are basically the same as those in the first embodiment, except that the content of each material in the wood-plastic material mixture and the polymer foam material mixture is different.

[0020] The wood-plastic material mixture contains: 75kg of polyvinyl chloride, 50kg of active calcium carbonate, 40kg of wood flour, 1kg of calcium stearate, 3kg of organic thinner, 3kg of foaming agent, 3kg of calcium zinc stabilizer, 6kg Titanium dioxide, 0.8kg of UV agent and 2kg of chlorinated polyethylene.

[0021] The polymer foam layer material contains: 100kg of polyvinyl chloride, 30kg of active calcium carbonate, 3kg of organic dilute, 3.5kg of foaming agent, 15kg of calcium zinc stabilizer, 3kg of titanium dioxide, 2kg of chlorinated polyvinyl chloride Ethylene and appropriate amount of toner.

Embodiment 3

[0023] The specific operation steps in the third embodiment are basically the same as those in the first embodiment, except that the content of each material in the wood-plastic material mixture and the polymer foam material mixture is different.

[0024] The wood-plastic material mixture contains: 62.5kg of polyvinyl chloride, 32.5kg of active calcium carbonate, 21kg of wood powder, 0.75kg of calcium stearate, 1.95kg of organic dilute, 1.75kg of foaming agent, 5.5kg of Calcium zinc stabilizer, 4.5kg of titanium dioxide, 0.55kg of UV agent and 1.25kg of chlorinated polyethylene.

[0025] The polymer foam layer material contains: 87.5kg of polyvinyl chloride, 20kg of activated calcium carbonate, 2kg of organic dilute, 2.5kg of foaming agent, 12kg of calcium zinc stabilizer, 1.75kg of titanium dioxide, 1.25kg of Chlorinated polyethylene and appropriate amount of toner.

Abstract

The invention discloses a wood-plastic floor processing method which comprises the following steps that: first, wood-plastic material and polymer foam are respectively extruded through an extruder simultaneously, and then the two extruded materials form the floor with the polymer foam material in the middle part and the wood-plastic material on the surface through a forming mold simultaneously. The middle part of the floor processed through the method is provided with the polymer foam material, and the surface thereof is provided with the wood-plastic material; the weight of the polymer foam material is lighter, the template quality can be effectively reduced, the middle part of the floor is solidly filled, so that the floor looks more beautiful; and the wood-plastic material on the surface of the floor can fully ensure the surface hardness and the strength of the floor, and does not affect the use quality of the floor. Therefore, the wood-plastic floor has the advantages of light weight and attractive appearance.

Description

technical field [0001] The invention relates to a wood-plastic floor, in particular to a processing method for a PVC wood-plastic floor. Background technique [0002] Wood-plastic composites (Wood-Plastic Composites, WPC) is a new type of composite sheet material that has been booming at home and abroad in recent years. It is formed by hot extrusion after mixing plastic and wood powder in a certain proportion. The wood-plastic composite material contains plastic, so it has a good modulus of elasticity. In addition, because it contains fibers and is fully mixed with plastic, it has physical and mechanical properties equivalent to hardwood, such as compression resistance and bending resistance, and its durability Obviously better than ordinary wood materials. The surface hardness is high, generally 2-5 times that of wood. Due to the above advantages, it is widely used in building materials, furniture, logistics packaging and other industries. [0003] The floor made of wood-...
