Abstract

The invention discloses a high polymer plant fiber composite floor. Polyvinyl chloride resin is taken as a raw material of an inner layer, 300-mesh bamboo powder treated by aluminate ester is taken as a filling material, a proper amount of an additive is added for mixing, a microfoaming and extrusion process is used for preparation; for a surface layer, organobentonite and the 300-mesh bamboo powder treated by the aluminate ester are mixed with polyvinyl chloride resin and a proper amount of the additive, and then subject to once composite coextrusion with the inner layer to form a skinned surface layer of the high polymer plant fiber composite floor. The high polymer plant fiber composite floor has the advantages of light weight, high strength, simple preparation process and no formaldehyde pollution.

Description

High polymer plant fibre composite floor

Technical field

The present invention relates to a kind of wood and mould plate, particularly a kind of high polymer plant fibre composite floor.

Background technology

At present, Wood-plastic floor in market sale is to be primary raw material with the Corvic, adding wood powder and calcium carbonate is packing material, process by traditional extrusion technology, exist problems such as intensity is low, weight is big, and is yielding, and the surface is to adopt ink printing and handle through high-abrasive material to form, it is low to exist production efficiency, problems such as manufacturing cost height.

Summary of the invention

The purpose of this invention is to provide a kind of in light weight, intensity is high, the simple architectural decoration of manufacturing process floor.The technical solution used in the present invention is: internal layer is primary raw material with the Corvic, is packing material with the 300 order bamboo powder of handling with aluminic acid lipoprotein, adds an amount of additive and mixes, and adopts the manufacturing of little foaming expressing technique; Surface course adopts after organobentonite and the 300 order bamboo powder blend of handling with aluminic acid lipoprotein and Corvic and an amount of additive mix, by being processed into high polymer plant fibre composite floor skinning surfaces layer with the once-combined co-extrusion of internal layer.

String production process route of the present invention is:

1, bamboo chip, bamboo leftover pieces;

2, fragmentation;

3, drying and grinding;

4, surfacing.

High polymer plant fibre composite floor production process route of the present invention is:

1, batching;

2, mix;

3, inside and outside layer composite co-extruding;

4, mould molding;

5, cooling forming;

6, traction;

7, cutting.

High polymer plant fibre composite floor surface course prescription of the present invention is (seeing Table 1):

Table 1

That the present invention has is in light weight, intensity is high, manufacturing process is simple, formaldehydeless pollution characteristics.

Below in conjunction with embodiment the present invention is described further.

The specific embodiment

A kind of embodiment of high polymer plant fibre composite floor of the present invention is:

1, processing string (modification bamboo powder): with bamboo chip or leftover pieces fragmentation, drying, grind to form fineness 300 purpose bamboo powder after, mixes stirrings with aluminic acid lipoprotein, carry out surface coating processing, aluminic acid lipoprotein is coated on bamboo powder surface.

2, be equipped with the internal layer raw material: by weight, the internal layer raw material is made in 100 kilograms of Corvics, 4 kilograms of calcium-zinc composite stabilizing agents, 3 kilograms of stearic acid, 2 kilograms of paraffin, 2 kilograms of ABS, 1 kilogram of blowing agent, 0.3 kilogram of fire retardant, 0.5 kilogram of aluminic acid lipoprotein, the blend of 60 kilograms of modification bamboo powder.

3, be equipped with outer raw material: by weight, to have after 1 kilogram of machine swell soil and the blend of 35 kilograms of modification bamboo powder and the internal layer raw material is made in 100 kilograms of Corvics, 4 kilograms of calcium-zinc composite stabilizing agents, 2 kilograms of stearic acid, 1 kilogram of paraffin, 1 kilogram of ABS, 0.2 kilogram of colorant, 0.3 kilogram of fire retardant, 0.5 kilogram of aluminic acid lipoprotein blend.

4, will be equipped with good internal layer raw material and become the ectonexine composite plate with the once inside and outside layer of extruder composite co-extruding with outer raw material, internal layer adopts little foaming expressing technique during co-extrusion, through mould molding, cooling forming, traction, cutting, make high polymer plant fibre composite floor of the present invention again.

Claims (1)

1, a kind of high polymer plant fibre composite floor is characterized in that internal layer is primary raw material with the Corvic, is packing material with the 300 order bamboo powder of handling with aluminic acid lipoprotein, adds an amount of additive and is mixed and made into; After surface course adopts organobentonite and 300 order bamboo powder blend with the aluminic acid lipoprotein processing, be mixed and made into Corvic and an amount of additive, internal layer raw material and outer raw material form with the once inside and outside layer of extruder composite co-extruding, and internal layer adopts little foaming expressing technique during co-extrusion.
