Problems solved by technology

Especially the tent mat itself is relatively thick, so it needs to be folded as small as possible for the convenience of carrying. If the low temperature resistance of the tent mat is not good enough, the crease will break after a period of use.

Abstract

The invention relates to a low-temperature-resistant elastomer resin material applicable to extremely-cold polar regions and a preparation method thereof. The low-temperature-resistant elastomer resinmaterial comprises the following raw materials by weight: 20-30 parts of an ethylene-octene block copolymer, 15-25 parts of a hydrogenated styrene-butadiene block copolymer, 20-25 parts of ethylene propylene diene monomer, 10-15 parts of a polypropylene random copolymer, 7-10 parts of polystyrene, 0.5-0.8 part of 2,4-dichlorobenzoyl peroxide, 0.5-1 part of dibenzothiazyl disulfide, 1-2 parts of bis(1,5-pentylidene) thiuram tetrasulfide, 0.2-0.5 part of zinc ethylphenyl dithiocarbamate, 1-2 parts of 4-4'-dimorpholinyl disulfide, 1-2 parts of methyl methacrylate monomers and 1-2 parts of a silane coupling agent. The material prepared by the invention has the advantages of extremely low-temperature resistance, good aging resistance, high elasticity, no toxicity, no odor, environmental friendliness, recyclability and low cost.

Description

technical field [0001] The invention relates to a low-temperature-resistant elastomeric resin material suitable for polar and extremely cold regions and a preparation method thereof. Background technique [0002] Almost two-thirds of the world's population in 51 countries participated in the polar scientific expedition, including the world's economically developed countries and major developing countries. It is related to global changes and the future of mankind. It is also a country's comprehensive national strength and high-tech level in the international arena.
