Abstract

The invention discloses an aliphatic acid zinc soap rubberlike internal releasing agent. Raw materials of the aliphatic acid zinc soap rubberlike internal releasing agent comprise, by mass, 450-650 kg of stearic acid, 25-40 kg of zinc compounds, 350-450 kg of octadecanamide, 90-100 kg of paraffin and 5-15 kg of DiethyleneGlycol; a preparation method of the aliphatic acid zinc soap rubberlike internal releasing agent comprises the steps that 1 the stearic acid is put, quantitative stearic acid is put in a reaction still and heated and stirred; 2 the zinc compounds are put; 3 the octadecanamide, the paraffin and the DiethyleneGlycol are put in sequence; 4 product prilling is conducted; 5 a product is packed. According to the aliphatic acid zinc soap rubberlike internal releasing agent, an internal lubrication function is obtained, the viscosity of a rubber material can be reduced, the flowing property of the rubber material can be improved, the force of friction between the rubber material and the surface of a metal when contacts can also be lowered, and sliding between the rubber material and the metal is improved; accordingly, the demoulding property of a finished product is improved, and the demoulding effect on a complex mould is particularly good.

Description

technical field [0001] The invention relates to the field of rubber additives, in particular to a fatty acid zinc soap type rubber internal release agent. Background technique [0002] The release agent is a functional substance between the mold and the rubber product. Its function is to prevent the rubber product from sticking to the mold, resulting in serious appearance defects of the rubber product, and to prevent the pollution of the vulcanized mold. The release agent can help the rubber product to be taken out of the mold smoothly, ensure the appearance of the product is qualified, reduce the loss of waste products, and improve production efficiency and economic benefits. [0003] There are two types of release agents. One is the external spraying type, which is directly sprayed on the vulcanization mold. Due to the use of powder as the carrier, the environmental pollution of the workshop is serious and the cost is high; one is the internal rubber release agent, ...
