Abstract

The invention discloses a cold-resistant drive belt primer and a preparation method thereof. The cold-resistant drive belt primer is made from the materials in parts by weight: 50-70 parts of chloroprene rubber (CR), 30-50 parts of butadiene rubber (BR), 1-10 parts of cold-resistant additive, 1-10 parts of magnesium oxide (MgO), 0.5-15 parts of zinc oxide (ZnO), 1-6 parts of accelerant, 1-5 parts of stearic acid (SA), 40-60 parts of reinforcing agent, 1-10 parts of anti-aging agent, 1-10 parts of plasticizer, 1-2 parts of sulphur (S) and 5-10 parts of oil. According to the cold-resistant drive belt primer, the cold-resistant additive, the vulcanizing agent, the accelerant, the stearic acid, the reinforcing agent, the anti-aging agent and the plasticizer act synergistically to jointly improve the low temperature crystallization-resistant property of the drive belt at the temperature of -10 DEG C under the premise of keeping physical properties of the drive belt such as break strength, tear strength, hardness and elongation at break.

Description

technical field [0001] The invention belongs to the technical field of transmission belts, and relates to a primer for cold-resistant transmission belts and a preparation method thereof. Background technique [0002] Most of the transmission belts for agricultural machinery are made of neoprene. Neoprene has high tensile strength, elongation, aging resistance, and heat resistance. It is an important raw material for medium and high-end transmission belts, but its disadvantage is its cold resistance. and poor storage stability. Due to the regularity of the molecular chain of neoprene itself and the presence of polar side groups, it has the characteristics of easy crystallization, so when the ambient temperature is below zero, the neoprene begins to crystallize, gradually hardens and becomes brittle and cracks. The crystallization rate is the fastest when the temperature is -10°C, and the result of hardening and brittleness is that the flex resistance of neoprene becomes poor,...
