Embodiment 1

[0020] The raw materials of the high cold-resistant slurry and their proportions by weight are: 100 parts of PVC resin powder, 15 parts of TPU resin, 8 parts of cold-resistant agent DOA, 50 parts of epoxy soybean oil, 5 parts of color cake, 2 parts of potassium zinc stabilizer, 2 parts of azodicarbonamide, 30 parts of 2000 mesh superfine calcium carbonate.

[0021] According to the ingredients, the above-mentioned materials measured are input into the high-speed mixer through the pulse feeder, and the temperature is controlled at 100-150 ° C. After fully stirring, they enter the internal mixer, and the temperature is controlled at (150 ° C) for several minutes; After the base material (various fabrics) is opened, apply PU slurry (150°C), combine the fully mixed material with the base material with PU slurry, enter the second rolling mill (160°C) for kneading, and then After entering the four-roll calender (temperature 160-190°C) and calendering, it is cooled to room temperatur...

Abstract

The invention discloses high-cold-resistant synthetic leather which is prepared by adding high-cold-resistant sizing agent and adopting a calendering method. The high-cold-resistant sizing agent is prepared by the following components in parts by weight: 100 parts of PVC (polyvinyl chloride) resin powder, 10-20 parts of TPU (Thermoplastic polyurethanes) resin, 5-10 parts of cold-resisting agent, 40-60 parts of epoxy soybean oil, 2-10 of color cakes, 3-7 parts of stabilizer and foaming agent, and 10-40 parts of ultra-fine filler. The synthetic leather has not only good mechanical properties, but also ultra-high cold-resisting characteristics, and can pass a minus 60 DEG C low temperature bending test.

Description

technical field [0001] The invention belongs to the field of synthetic leather manufacture, and in particular relates to a high cold-resistant synthetic leather and a preparation method of the high cold-resistant synthetic leather. Background technique [0002] Synthetic leather is the first invention to be used as a substitute for leather fabrics. It is made of PVC, plasticizer and other additives and calendered on cloth. At present, in the production process of domestic PVC decorative synthetic leather, plasticizers, PVC resin powder, heavy calcium, stabilizers, foaming agents, and other main raw materials are usually used. This kind of synthetic leather tends to harden and become brittle, especially when it is used outdoors in cold northern regions, frozen food packaging, and the covering layer has a low temperature, and it is easy to break and crack. Contents of the invention [0003] The purpose of the present invention is to provide a kind of synthetic leather which...
