Abstract
The invention is a light composite building material, relating to a light high-strength composite building material. The invention provides a light high-strength composite building material. Its producing raw materials are composed of waste low-density polyethylene 5-25%, polyamide 6 5-25%, PVC 10-25% and wood powder 50-70%; the making method: adding dissolved waste low-density polyethylene, polyamide 6 and PVC and wood powder in proportion in a blender in proportion, uniformly blending and then making die forming by pour mold. The product of the invention has high strength, low weight, and without pollution.
Description
Technical field
The present invention relates to a kind of is raw material with waste and old new LDPE (film grade), polyamide 6, polyvinyl chloride and wood powder, have in light weight, the composite building material that intensity is high.
Background technology
How the various building materials of construction industry use at present are based on concrete and wood fibre board.With the composite building material that materials such as cement, mortar, concrete, slag are made, the intensity height, but weight is big; With the composite building material that wood fibre board makes, in light weight, but intensity is under some influence again.
Technology contents of the present invention:
The purpose of this invention is to provide a kind of in light weightly, intensity is high, is the composite building material of raw material with new LDPE (film grade), polyamide 6, polyvinyl chloride and wood powder.
The present invention is achieved through the following channels:
The main raw material of lightweight composite building material is added wood powder and is formed by waste and old new LDPE (film grade), polyamide 6, polyvinyl chloride, waste and old raw material new LDPE (film grade), polyamide 6, polyvinyl chloride are through heating, after stirring fully with the wood powder batching, after injection molding compression molding, the drying, carry out surface treatment.The cooperation ratio of main raw material: waste and old new LDPE (film grade) is that 5-25%, polyamide 6 are that 5-25%, polyvinyl chloride are that 10-25%, wood powder are 50-70%.Wood powder comprises: various xyloid sawdust mixtures are done stopping composition.The Heating temperature of waste and old new LDPE (film grade) and polyamide 6 is 130-170 ℃, and the Heating temperature of polyvinyl chloride is 180-220 ℃.
Manufacture method is that waste and old new LDPE (film grade), polyamide 6, polyvinyl chloride and wood powder as the adhesive solidification agent add in the mixing agitator in proportion with dissolved, after stirring, and the injection molding compression molding.
Beneficial effect of the present invention: 50-70% utilizes wood powder in the raw material, and wood powder comprises: various xyloid sawdust mixtures.Alleviate the weight of product, can also reduce pollution; Add the intensity that has improved product behind waste and old new LDPE (film grade), polyamide 6, the polyvinyl chloride, have wear-resisting, oil resistant, waterproof, fire prevention, antidetonation, halogenation, heat insulation performance; The product that present method is made can bore, saws, paste, and is indeformable; Noiselessness during production, pollution-free.
Specific embodiment:
Embodiment 1: earlier with the waste and old new LDPE (film grade) of 5-25%, the waste and old polyamide 6 of 5-25%, the waste polyvinyl chloride of 10-25%, add the dissolving of heating in the dissolving stove respectively, the Heating temperature of waste and old new LDPE (film grade) and polyamide 6 is 160 ℃, and the Heating temperature of waste polyvinyl chloride is 220; The dissolving back adds is equipped with in the mixing agitator of 50-70% wood powder, after stirring, and injection molding compression moulding.After the drying, its surface is handled.
Embodiment 2: design the raw material with 100 kilograms, after earlier 10 kilograms of waste and old new LDPE (film grade)s, 10 kilograms of waste and old polyamide 6s, 15 kilograms of waste polyvinyl chlorides being distinguished heating for dissolving, again with 65 kilograms sawdust mixing wood powder, in agitator after the mixing and stirring, injection molding compression moulding, after the drying, its surface is handled.
Embodiment 3: design the raw material with 100 kilograms, after earlier 15 kilograms of waste and old new LDPE (film grade)s, 10 kilograms of waste and old polyamide 6s, 20 kilograms of waste polyvinyl chlorides being distinguished heating for dissolving, again with 65 kilograms various xyloid sawdust, in agitator after the mixing and stirring, injection molding compression moulding, after the drying, its surface is handled.
When making product of the present invention, can be according to client's needs, suitably adjust the per-cent of desired raw material and handle the Heating temperature of waste and old new LDPE (film grade), polyamide 6, polyvinyl chloride.
Claims (4)
