Embodiment Construction

[0013] The PVC microcrystalline stone foam floor of the present invention is made of the raw materials of following weight ratio:

[0014] PVC 4.95kg, microcrystalline stone 3.96 kg, stabilizer (composite stabilizer sw-206) 0.34 kg, foam modifier (acrylate foam regulator zB-530) 0.34 kg, foaming agent 0.07 kg, lubricant 0.06 kg, 0.39 kg of copolymer of styrene, acrylonitrile and methacrylic acid.

[0015] Production process of the present invention is as follows:

[0016] Put PVC, microcrystalline stone, and stabilizer into a high-speed mixer according to the proportion, mix and heat up to 80 degrees, then add all other additives and mix and heat up to 125 degrees, then unload into the cold mixing bucket and mix to cool to 40 degrees, put the cold The mixed raw materials are put into the conical double extruder (different temperature setting and extrusion speed of each section of the extruder), the material is plasticized and flowed in the screw and extruded through the extru...

Abstract

The invention relates to the technical field of a chemical building material and particularly provides a PVC (polyvinyl chloride) microlite foamed floor. The PVC microlite foamed floor is formed by the following components by weight percent: 49.5% of PVC, 39.6% of microlite, 3.4% of stabilizing agent, 3.4% of foaming modifying agent, 0.7% of foaming agent, 0.6% of lubricating agent and 3.9% of a copolymer of styrene, acrylonitrile and methacrylic acid. The PVC microlite foamed floor has the beneficial effects that 1, a glue type binding agent cannot be used, no formaldehyde exists and fungus does not grow; 2, the water absorbing capacity is low, the floor is not deformed when being immersed in water for long time, the wear resistance is good and worms cannot grow, a solid wood floor is not waterproof, a sintered floor and a floor brick are not damp-proof and the solid wood floor is easily damaged by worms; 3, the floor does not contain heavy metals and can be recycled and reutilized, while the sintered floor, the solid wood floor and the floor brick basically cannot be recycled and reutilized; and 4, textures are beautiful, the elasticity is good, the floor is comfortable and wear-resisting and the density is moderate and is 0.8-1.0, while the density of the sintered floor, the floor brick, a stoned molded floor and the like is about 1.5-2.0, so that the weight of a high-rising building can be reduced and the transportation cost is reduced.

Description

technical field [0001] The invention relates to the technical field of chemical building materials, in particular to a foamed floor made of PVC microcrystalline stone. Background technique [0002] In the current field of building materials, imitation plastic boards and PVC foam boards are widely used as decorative boards, but they usually have the following problems: 1. The strength of the product is not high, the service life is short, and it is easy to break or crack when encountering external force; 2. Poor geometric stability, easy to deform at high temperature, and prone to embrittlement at low temperature; 3. Has certain chemical toxicity; 4. Poor wear resistance. Contents of the invention [0003] The purpose of the present invention is to provide a PVC microcrystalline stone foam floor to solve the technical problems of low product strength, short service life, poor geometric dimension stability and chemical toxicity in the existing imitation plastic decorative...
