Embodiment 1

[0015] A method for preparing flame-retardant, low-smoke, low-temperature-resistant, and cigarette-resistant PVC flooring. First, the ingredients: weigh 100 parts by weight of PVC, 50 parts by weight of dioctyl phthalate, and 12 parts by weight of dioctyl sebacate , 4 parts by weight of stabilizer, 6 parts by weight of lubricant, 40 parts by weight of magnesium hydroxide, 80 parts by weight of aluminum hydroxide, 2 parts by weight of titanate coupling agent, 10 parts by weight of zinc borate;

[0016] Put the aluminum hydroxide into the high-speed processing machine, add the mixture of titanate coupling agent and lubricant dropwise when the temperature is 40°C, the lubricant can be white oil, and cool at 70°C for later use;

[0017] Put magnesium hydroxide into a high-speed processing machine, add dropwise a mixture of titanate coupling agent and lubricant at a weight ratio of 1:1 at 40°C, and cool at 70°C for later use;

[0018] Put PVC into the high-speed kneader first and k...

Abstract

The invention discloses a preparation method of PVC flooring having fire retardance, low smoke, low-temperature resistance and cigarette burning resistance. The method comprises the following steps: (1) material proportioning; (2) packing processing; (3) high-speed co-mixing; (4) twin-roller plastication; and (5) mold pressing. The PVC flooring having the properties of fire retardance, low smoke, low-temperature resistance and cigarette burning resistance and produced through the five steps has stable product quality and high production efficiency.

Description

technical field [0001] The invention relates to the technical field of flooring, in particular to a preparation method of a flame-retardant, low-smoke, low-temperature-resistant, and cigarette-resistant PVC floor. Background technique [0002] With the development of my country's transportation industry, railway and highway passenger cars are constantly being introduced, and at the same time, higher requirements are put forward for passenger car floors. Soft PVC flooring has the advantages of easy paving, elegant appearance, durability, and low price, and has been widely used. But the prior art does not have a kind of preparation method that can produce the PVC floor that has flame retardant, low smoke, low temperature resistance, cigarette burning resistance that can produce stable product quality all the time. Contents of the invention [0003] The object of the present invention is to provide a preparation method of flame-retardant, low-smoke, low-temperature-resistant...
