Embodiment 1

[0030] S1: Put the raw materials of each component in a kneading pot and mix them evenly;

[0031] S2: Mixing is carried out in an internal mixer, and the mixing temperature is 130°C;

[0032] S3: Send the above kneaded material to the kneading roll for pre-calendering, and the roll temperature is 90°C;

[0033] S4: Put the pre-compressed sheet on a calender roll at 80° C. for calendering, cooling, punching and forming.

Embodiment 2

[0035] The difference from Example 1 is: the temperature in step S2 is 135° C.; the temperature in step S3 is 95° C.; the temperature in step S4 is 85° C.

Embodiment 3

[0037] The difference from Example 1 is: the temperature in step S2 is 140° C.; the temperature in step S3 is 100° C.; the temperature in step S4 is 90° C.

Abstract

The invention provides a high-strength plastic floor tile which is prepared from the following raw materials in parts by weight: 20-40 parts of PVC (polyvinyl chloride) resin, 3-5 parts of vinyl chloride-vinyl acetate copolymer resin, 1-3 parts of phenol formaldehyde resin, 3-5 parts of polyvinyl chloride resin, 2-4 parts of coumarone indene resin, 10-20 parts of chloroprene rubber, 1-2 parts of calcium sulfate, 2-3 parts of ground calcium carbonate, 3-6 parts of glass fiber, 8-14 parts of gypsum, 1-3 parts of titanium white, 5-15 parts of argil, 5-15 parts of aluminum oxide, 3-6 parts of magnesium oxide, 1-5 parts of barite powder, 1-2 parts of triethanolamine, 5-10 parts of paraffin, 8-16 parts of carbon black, 2-4 parts of dioctyl phthalate, 1-2 parts of anti-aging agent, 3-5 parts of plasticizer and 2-4 parts of silane coupling agent. The length variation under heating is less than 0.09%, the impact strength is up to more than 11KJ / m<2>, the bending strength is up to more than 110 MPa, and the thermal decomposition temperature is up to higher than 185 DEG C.

Description

technical field [0001] The invention provides a plastic floor tile, in particular relates to a plastic floor tile with relatively high mechanical performance, and belongs to the technical field of building decoration materials. It has the advantages of low price, good decorative effect, good heat insulation performance, convenient construction, light weight and easy maintenance. Background technique [0002] With the rapid development of my country's construction industry and the improvement of people's living standards, people's requirements for interior decoration are also increasing. Floor tiles are currently a major interior decoration material, generally divided into ceramic floor tiles, marble floor tiles, wood floor tiles, etc. Wooden floor tiles are generally installed on the ground by nails or screws, and connected with each other by adhesives, but this type of floor tiles are afraid of moisture and are prone to mildew. Although marble floor tiles can withstand mo...
