Problems solved by technology

Although the above method can increase the connection strength of the PVC floor, there are generally two major defects: one is that the installation is time-consuming and laborious, and the other is the increase in the cost of the PVC floor
[0004] In addition, there is another kind of PVC foam floor on the market. This kind of floor is moderately soft and hard, and is suitable for processing lock structure. However, this kind of floor is generally formed by extrusion, which has low production efficiency and poor dimensional stability, and is not suitable for calendering. Mass production

[0038] The high-hardness plastic pavement material of the present invention is a composite material, which can be used not only for laying the ground, but also for laying ceilings, walls, wardrobes and the like. In the present invention, the high-hardness plastic paving material is preferably composite flooring. Such as figure 1 As shown, the high-hardness plastic paving material includes a UV coating 11 , a surface protection layer 12 , a decoration layer 13 and a base layer 14 from top to bottom.

[0039] The UV coating 11 is formed on the surface protection layer 12 . In other embodiments of the present invention, the UV coating 11 may be omitted as appropriate.

[0040] The thickness of the surface protection layer 12 is 0.05-1.5mm, and the surface protection layer 12 can be made of rigid polyvinyl chloride transparent film, rigid polyester transparent film or other suitable materials. The rigid polyvinyl chloride transparent film or the rigid polyester transparent film...

[0047] The UV coating 11, the surface protection layer 12, and the decorative layer 13 of the high-hardness plastic pavement material of the present embodiment are completely the same as the high-hardness plastic pavement material of the first embodiment, and the differences between the present embodiment and the first embodiment in the base layer 14 . In this embodiment, no liquid plasticizer is added to the material of the base layer 14 . In this embodiment, the mass percentages of the components in the base layer 14 are as follows: PVC resin 100wt%, solid plasticizer 10-60wt% (preferably 30-60wt%), additives 60-510wt% (preferably 150-350wt%, the best is 225-300wt%).

[0048] Among the components of the base layer 14, the additive is a mixture of stone powder and other additives. Other additives in the present invention can be at least one of PVC common additives such as stabilizer, flame retardant, smoke suppressant, antioxidant. The solid plasticizer is a modified envir...

[0051] The UV coating 11, the surface protection layer 12, and the decorative layer 13 of the high-hardness plastic pavement material of the present embodiment are completely the same as the high-hardness plastic pavement material of the first embodiment, and the differences between the present embodiment and the first embodiment in the base layer. In this embodiment, the base layer includes two layers of the middle material layer 15 and the bottom material layer 17, and the components of the middle material layer 15 and the bottom material layer 17 are the same as those of the base layer in the first embodiment, and the difference is only in the composition mass percentage. The mass percent of each component in the middle material layer 15 is as follows: PVC resin 100wt%, solid plasticizer 10~60wt%, liquid plasticizer 0.1~10wt%, additive 125~400wt% (preferably being 150~350wt%, The optimum is 225-300wt%), wherein the additive is a mixture of stone powder and other additives....

Abstract

The invention relates to a high-hardness plastic paving material. The high-hardness plastic paving material comprises a matrix layer, wherein the matrix layer contains 100wt% of PVC resin, 10wt%-60wt% of a solid plasticizer and 60wt%-510wt% of an additive, and the solid plasticizer is selected from modified environment-friendly plastic and / or EPDM with a melting temperature of 50-150 DEG C. By adding the solid plasticizer is into the matrix layer of the plastic paving material and utilizing a reasonable formula design, the hardness of the high-hardness plastic paving material is remarkably improved; and because the melting temperature of the selected solid plasticizer is lower than a calendering temperature of PVC, the fluidity of the PVC during melting can be improved, and calendering formation is facilitated.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a high-hardness plastic paving material for surface paving. Background technique [0002] The floor used as an interior decoration building material is usually divided into raw wood floor, stone floor, rubber floor, linen floor and composite floor according to the raw material. Composite flooring generally includes composite wood flooring, wood-plastic flooring, PVC (polyvinyl chloride) flooring, and the like. Among the above-mentioned several types of flooring, raw wood flooring, composite wood flooring and linen flooring have problems such as poor water resistance and easy deformation due to the use of fiber materials as base materials. Stone does not keep heat and is easy to slip, especially in the rainy season, accidents often occur due to the floor being too slippery and causing injuries. Rubber flooring has good comprehensive properties, but its high price and strict ins...
