Description
Technical Field
The invention belongs to the technical field of floor production and extrusion mechanical equipment, and particularly relates to a WPC (wood-plastic composite) substrate traction heating device.
Background
WPC flooring is also one of the PVC flooring. The main raw materials of the material are polyvinyl chloride, calcium powder, a stabilizer, a foaming agent and the like. The WPC floor is light, thin, wear-resistant, good in elasticity, fireproof, flame-retardant, water-absorbing, moisture-proof, sound-absorbing and noise-preventing, and particularly simple, convenient and pollution-free in installation. The WPC floor is generally accepted in large and medium-sized cities at home and abroad after being developed for a few years, and is widely used.
The conventional WPC flooring production process can be summarized as follows: the foamed sheet material extruded by the main machine is cooled and formed by a shaping die cooled by a water cooler, the shaping die generally comprises three to four sections, each section is 500 mm to 600 mm in length, is connected with a section of bracket for cooling (edge cutting is generally arranged on the bracket), is drawn by 6 to 8 groups of tractors, and is cut into sheets with different specifications, namely the base material. And then a surface skin is made by a press or a laminating line, and the surface skin generally consists of a wear-resistant layer, a color film and an LVT (laminated veneer lumber) backing material. Then the base material and the wrapper are bonded by glue and then put on a cold press to be statically placed for 6 to 8 hours to form a semi-finished floor product.
The above is the conventional process for producing the WPC floor on the market at present. The plate-type stock mold has the advantages of accurate wall thickness of the base material and high surface hardness of the base material. The defects are that the shrinkage rate of the base material is large and the raw materials are wasted. The dough needs to be made into a wrapper by a hot press or a laminating line, the wrapper is laminated by a glue coating machine, and the wrapper is molded by the press under secondary pressure maintaining. The process is complicated, the equipment cost is high, and the labor cost is high. Meanwhile, because glue is needed for bonding, certain pollution still exists, and the environment is not protected.
The SPC floor board is produced through extruding sheet from the main machine, rolling to form, and once forming with rollers to form the floor board. The film can be coated on line without using glue. The process is simple, the equipment cost and the labor cost are low, and no pollution of 0-formaldehyde is really realized. However, the roller-type sizing die has the disadvantages that the foamed base material is not accurately sized in thickness and the hardness of the surface of the base material is relatively low.
