Embodiment 1

[0019] First put 50 parts by weight of nitrile rubber and 10 parts by weight of natural rubber into the mixing chamber, keep the temperature in the mixing chamber at 60°C, and keep the pressure at 0.2Mpa. After pressing down for 5 minutes with the pressing hammer, it will rise, and then put in 5 parts by weight of polyvinyl chloride powder and 1 part by weight of dioctyl phthalate, mixed evenly, and pressed down with a pressing hammer for 3 minutes to obtain a mixer; then mix the mixer with 1 part by weight of sulfur powder, 3 parts by weight of Zinc, 1 part by weight of dibenzothiazole disulfide and 1 part by weight of N-phenyl-1-naphthylamine were put into a banbury mixer and pressed together for 3.5 minutes, mixed evenly and then discharged after banburying at 80°C for 5 minutes; The mixed rubber is discharged into the designated mold for cooling and forming, and then cut and processed according to the requirements to obtain high-strength and low-temperature resistant materi...

Embodiment 2

[0021] First put 60 parts by weight of nitrile rubber and 60 parts by weight of natural rubber into the mixing chamber, keep the temperature in the mixing chamber at 70°C, and keep the pressure at 0.2Mpa. After pressing down for 5 minutes with the pressing hammer, it will rise, and then put in 10 parts by weight of polyvinyl chloride powder and 1.5 parts by weight of diisononyl phthalate, after mixing evenly, the pressing hammer was pressed down for 3 minutes to obtain the mixer; then mix the mixer with 2 parts by weight of sulfur powder, 5 parts by weight of Zinc carbonate, 3.5 parts by weight of tetramethylthiuram disulfide and 1.5 parts by weight of N-phenyl-N'-isopropyl-p-phenylenediamine were put into the internal mixer and pressed for 2 minutes, and mixed uniformly at 90°C After banburying for 4 minutes, the material is discharged; the mixed rubber is discharged into the designated mold for cooling and forming, and then cut and processed according to the requirements to o...

Embodiment 3

[0023] First put 70 parts by weight of nitrile rubber and 30 parts by weight of natural rubber into the mixing chamber, keep the temperature in the mixing chamber at 90°C, and keep the pressure at 0.2Mpa. After pressing down for 5 minutes with the pressing hammer, it will rise, and then put in 13 parts by weight of polyvinyl chloride powder and 2 parts by weight of dioctyl phthalate, after mixing evenly, the pressing hammer was pressed down for 3 minutes to obtain the mixer; then mix the mixer with 1.8 parts by weight of sulfur powder, 4.5 parts by weight of carbonic acid Calcium, 4 parts by weight of dibenzothiazole disulfide and 2 parts by weight of 2-mercaptobenzimidazole were put into a banbury mixer and pressed for 5 minutes, mixed evenly and then banburyed for 4.5 minutes at 100°C before discharging; the mixed rubber was discharged Put it into the designated mold for cooling and forming, and then cut and process according to the requirements to obtain high-strength and lo...

Abstract

The invention discloses a high-strength low-temperature-resistant material for shoes and a preparation method of the high-strength low-temperature-resistant material.The material is prepared from, by weight, 50-80 parts of butadiene-acrylonitrile rubber, 10-60 parts of natural rubber, 1-3 parts of a vulcanizing agent, 3-8 parts of an activating agent, 1-5 parts of accelerant, 1-3 parts of an anti-aging agent, 5-20 parts of polyvinyl chloride powder and 1-5 parts of plasticizer.The prepared high-strength low-temperature-resistant material for shoes can overcome the defects that cold resistance is poor, the flowing property is low and the like when only polyvinyl chloride is used and can give full play to the advantages of butadiene-acrylonitrile rubber, such as high strength and good processing properties.The prepared material is low in price, easy to obtain, simple in preparation process and high in strength, the tensile strength of the material at the normal temperature is 19-23 MPa, the tensile strength of the material at the low temperature is 15-19 MPa, cold resistance and processing properties are excellent, wear resistance at the low temperature is remarkable, almost no trace is left when human body walking bending is simulated for ten thousand cycles or more, and the high-strength low-temperature-resistant material can be used for producing low-temperature-resistant shoe soles and other cold-resistant auxiliary materials.

Description

technical field [0001] The invention relates to the field of shoes, and more specifically relates to a high-strength low-temperature resistant material for shoes and a preparation method thereof. Background technique [0002] In order to meet the differences in geographical conditions and meet the needs of extremely harsh low-temperature environments, the current market puts forward new requirements for special functions of footwear, especially in the field of safety shoes, which require higher cold resistance, strength and hardness of footwear. . However, the cold-resistant sports shoes currently on the market have complex manufacturing processes and expensive materials. The price is often ten times or even dozens of times that of ordinary footwear, and the performance is not stable enough. [0003] According to the current research status of the rubber shoes industry, polyvinyl chloride or natural rubber is mainly used as the main material for the production of the shoe b...
