Preparation method of rubber with abrasion-resistant and low temperature-resistant properties

Abstract

The invention discloses a preparation method of rubber with abrasion-resistant and low temperature-resistant properties. The preparation method comprises the following steps of adding natural rubber into universal rubber mixing equipment, and plasticizing; adding liquid fluorinated silicone rubber and butadiene rubber, uniformly mixing, then adding cerium oxide, modified filler, phenylmethylsilicone fluid, white oil, an antioxidant 168 and a silane coupling agent kh550, and mixing, so as to obtain mixed rubber; staying the mixed rubber overnight, adding the remaining raw materials, and vulcanizing the mixed rubber by a conventional rubber vulcanizing technology, so as to obtain the rubber. The prepared rubber has the advantages that the proportional ratio of the components is reasonable, the abrasion-resistant property is good, the low temperature-resistant property is excellent, and the application range is broad; by using a modifier to modify the filler, the compatibility of the filler is improved, and the abrasion-resistant property is improved; by strictly controlling the adding sequence of the raw materials, and adding the liquid fluorinated silicone rubber and butadiene rubber to mix, the low temperature-resistant property is obviously improved.

Description

technical field [0001] The invention relates to the field of rubber, in particular to a preparation method of wear-resistant and low-temperature resistant rubber. Background technique [0002] Natural rubber is a natural polymer compound with cis-1,4-polyisoprene as the main component, and 91% to 94% of its components are rubber hydrocarbons (cis-1,4-polyisoprene) , and the rest are non-rubber substances such as protein, fatty acid, ash, and sugar. Natural rubber is the most widely used general-purpose rubber. [0003] Natural rubber is widely used in the manufacture of rubber hoses and damping products. Because natural rubber has the disadvantages of easy loss of elasticity and hardness at low temperature, and low wear resistance. At present, there is an urgent need for new technologies to improve the low temperature resistance and wear resistance of natural rubber, so that it can be better used in the production and preparation of rubber hoses and shock absorbing produc...
