Description

The double-deck high hard pvc flooring of filling

Technical field

The invention belongs to the PVC floor, the particularly double-deck high hard pvc flooring of filling.

Background technology

The floor belongs to PVC hollow profile shapes to high filling RPVC (being called for short R one PVC), is to be primary raw material with polyvinyl chloride resin, adds heat stabilizer, impact modifier, sliding agent and filler, extrudes through batch mixes to form.Its width is respectively 55mm and 110mm.It is a kind of suitable with strength of wood, and more attractive in appearance, wear-resisting, moistureproof, mothproof, fire prevention and be prone to clean to mould substitute materials for wood.R one Pvc floor is installed on automobile, and each car can be saved Zm, and timber, thereby produce R one Pvc floor is exploitation second forest reserves, the offspring that benefits future generations, increase economic benefit and satisfy the major issue of market demand.In recent years, R one PVC floor was widely used in electric car, automobile and building.

The present invention provides a kind of new type double floor height to fill hard pvc flooring, satisfies the demand of growing R one PVC.

Summary of the invention

Goal of the invention

The present invention provides a kind of new type double floor height to fill hard pvc flooring, satisfies the demand of growing R one PVC.
