The sole material provided by the invention has the advantages of good cold resistance, good light aging-resistant performance and long service life.

Description

Technical field: [0001] The invention relates to a shoe sole material, in particular to a cold-resistant and light-resistant NBR shoe sole material and a preparation method thereof. Background technique: [0002] Nitrile Butadiene Rubber, English name Nitrile Butadiene Rubber, referred to as NBR, is made from butadiene and acrylonitrile by emulsion polymerization. Butadiene monomer can be copolymerized into three different chain structures: cis, trans and 1,2-alkyl. The trans form accounts for about 78% in a typical NBR structure. Because of the cyano group in the molecular chain structure of NBR, its oil resistance (such as resistance to mineral oil, liquid fuel, animal and vegetable oils and solvents) is better than natural rubber, neoprene and styrene-butadiene rubber. Compared with other rubbers, NBR has a wider The operating temperature of the domain. NBR has good chemical stability and good processing performance. With the increase of the content of acrylonitrile in...
