Abstract

The invention discloses a plastic-wood floor, in particular to the plastic-wood floor and a manufacturing method thereof, and aims to provide the plastic-wood floor with light weight, low contractibility and high flatness. The plastic-wood floor comprises a wear layer, a printed color film layer, a PVC (polyvinyl chloride) material layer and a plastic-wood composite layer sequentially from top to bottom; the plastic-wood composite layer consists of wood powder, PVC and a calcium carbonate material, wherein a weight ratio of the three materials is 1:3:6 in sequence; the plastic-wood floor has a simple process; the weight of a product with the same size is reduced by 25 percent, and meanwhile, the flatness of the product is also improved; and the plastic-wood floor is widely used for places, such as public places, stadiums and the like, and has the characteristics of convenience in use, long service life and the like.

Description

A kind of plastic-wood floor and manufacture method thereof

Technical field

The present invention relates to a kind of plastic-wood floor, especially a kind of plastic-wood floor and manufacture method thereof.

Background technology

Along with the requirement of environmental protection, the forest harvesting management is also more and more stricter, and people replace wood floors with plastic floor or plastic floor.Present plastic floor by wearing layer, print color rete, the PVC plastic layer consists of, and is compounded to form an integral body by heat between this three, although this plastics are wear-resisting, long service life, but the problems such as it exists that weight is large, shrinkage large, out-of-flatness.Whether there is a kind of technology to overcome existing plastic floor.

Plastic-wood floor be a kind of be basic material and thermoplastic macromolecule material PE plastics and processing aid etc. by timber (lignose, plant cellulose) mainly, the high-tech green material of making through die apparatus heating extrusion molding again after mixing, have performance and the feature of timber and plastics concurrently, can substitute the novel environment friendly hitech materials of timber and plastics.

Summary of the invention

The objective of the invention is to provide for the deficiency that solves above-mentioned technology a kind of lightweight, shrinkage is little, planeness is high plastic-wood floor and manufacture method thereof.

In order to achieve the above object, a kind of plastic-wood floor that the present invention is designed, it comprises wearing layer from top to bottom successively, print color rete, the PVC bed of material, mould wooden composite bed, describedly mould wooden composite bed and be made of wood powder, PVC and calcium carbonate material, the part by weight of described three kinds of materials is followed successively by 1:3:6.

Manufacture method:

The first step, the manufacturing of moulding wooden composite bed mixes wood powder, PVC and calcium carbonate, and rear used device carries out little foaming to be processed, and processing temperature is about 180 ℃; Foaming extrusion molding, and process by cooling forming immediately;

Second step, wearing layer, print color rete, the PVC plastic layer is composited by heat, its processing temperature is 125～140 ℃, after hot Combined Processing is complete, places it in thermostatic chamber 24h cooling constant temperature, after carry out surperficial UV and temper; After surface UV and the temper, be placed on thermostatic chamber and wait for that being cooled to room temperature prepares and mould the processing of fitting of wooden composite bed:

The 3rd step, the semiproduct that the first step and second step make to be fitted with glue, the product that applying is finished is put into hydraulic press and is carried out cold Compound Machining;

In the 4th step, moulding: the cold compound product of finishing is cut apart section, and the processing of slotting after the section obtains final products.

The resulting a kind of plastic-wood floor of the present invention, its technique is simple, and the product weight of same volume reduces 25%, and the planeness of product has also improved simultaneously, it is widely used in public places the place with stadiums etc., and it has the characteristics such as easy to use, that the life-span is long.

The specific embodiment

Embodiment 1:

A kind of plastic-wood floor that the present embodiment is described, it comprises successively from top to bottom wearing layer 1, printing color rete 2, the PVC bed of material 3, moulds wooden composite bed 4, describedly mould wooden composite bed 4 and be made of wood powder, PVC and calcium carbonate material, the part by weight of described three kinds of materials is followed successively by 1:3:6.

Manufacture method:

The first step, the manufacturing of moulding wooden composite bed 4 mixes wood powder, PVC and calcium carbonate, and rear used device carries out little foaming to be processed, and processing temperature is about 180 ℃; Foaming extrusion molding, and process by cooling forming immediately;

Second step, wearing layer 1, printing color rete 2, PVC plastic layer 3 are composited by heat, and its processing temperature is 125～140 ℃, after hot Combined Processing is complete, places it in thermostatic chamber 24h cooling constant temperature, after carry out surperficial UV and temper; After surface UV and the temper, be placed on thermostatic chamber and wait for that being cooled to room temperature prepares and mould the processing of fitting of wooden composite bed:

The 3rd step, the semiproduct that the first step and second step make to be fitted with glue, the product that applying is finished is put into hydraulic press and is carried out cold Compound Machining;

In the 4th step, moulding: the cold compound product of finishing is cut apart section, and the processing of slotting after the section obtains final products.
