Abstract

The invention discloses a polyvinyl chloride floorboard substrate and a preparation method thereof, belonging to the technical field of polyvinyl chloride boards. The polyvinyl chloride floorboard substrate solves the problems of high cost and poor quality in the existing product. The polyvinyl chloride floorboard substrate is prepared from 80-100 parts of polyvinyl chloride SG8 resin, 100-120 parts of heavy calcium carbonate, 50 parts of floorboard substrate moldboard reclaimed material, 7-8 parts of foaming regulator 903, 2-3 parts of foaming regulator 902, 2.8-4.9 parts of composite stabilizer, 0.6-1.2 parts of internal lubricant ZB-60, 0.35-0.7 part of polyethylene (PE) wax, 0.2-0.5 part of AP, 0.5-0.8 part of plasticizer OA3, 0.3-0.4 part of heat-release AC (azodicarbonamide) foaming agent, 1.4-1.6 parts of heat-absorption Zhongkai c-2 foaming agent, 2-5 parts of ferrite yellow powder and 2-4 parts of CPE (chlorinated polyethylene). The preparation method comprises the following steps: mixing, plastifying and foaming, and extruding to obtain the finished product. The product can be widely used in office buildings, shopping malls, schools, gymnasia, hospitals and other locations.

Description

technical field [0001] The invention relates to a polyvinyl chloride floor base material and a preparation method thereof, belonging to the technical field of polyvinyl chloride boards. Background technique [0002] PVC floor, also known as plastic floor, is an emerging high-tech flooring material in the world's building materials industry, and has been widely used in foreign decoration projects. PVC flooring has been vigorously promoted since it entered the domestic market in the 1980s. Now it is widely used in office buildings, shopping malls, airports, schools, libraries, gymnasiums, pharmaceutical factories, hospitals, factories and other industries, and has achieved satisfactory results. As an ecological floor, polyvinyl chloride floor has the advantages of being environmentally friendly, formaldehyde-free, flame-retardant, waterproof, moth-proof, moisture-proof, noise-proof, low-cost and recyclable, and has been accepted by more and more people. [0003] The productio...
