Problems solved by technology

Neoprene has good flame retardant and oil resistance properties, but its processing performance is relatively poor, and it is easy to stick to rolls and scorch in production engineering
CR-121 is a sulfur-modified chloroprene rubber, and its physical properties are much better than other varieties. At the same time, because CR-121 can be masticated by machines, its extrusion performance is better than other varieties, but its processing performance is poor. Hot, easy to burn

Abstract

The present invention relates to a production formula of a flame retardant dual density glue and a production technique. The glue comprises an outer layer glue and an inner layer glue. The outer layer glue consists of the following raw materials based on a weight share ratio: 20 to 40 of natural rubber, 20 to 40 of butadiene rubber, 3 to 7 of activated zinc oxide, 3 to 6% of light magnesium oxide, 1 to 3 of stearic acid, 2 to 4 of aging resister, 10 to 15 of flame retardant, 2 to 5 of terpene resin, 1 to 3 of petrolatum, 10 to 15 of N339 carbon black, 25 to 35 of N330 carbon black, 7 to 10 of transformer oil, 30 to 50 of chloroprene rubber, 0.2 to 0.8 of sulphur-80 and 2 to 3 of accelerator. The present invention makes the product meet the requirements of finished shoe soles for flame retardant and oil resistance.

Description

technical field [0001] The invention belongs to a novel sizing material formula and a production process thereof. Background technique [0002] When using DESMA injection molding to produce leather shoes, the main materials of the outsole of leather shoes are natural rubber and ordinary synthetic rubber, and the vulcanization speed of these general-purpose rubbers is generally relatively slow. In order to control the production efficiency to a single station residence time of about 30 seconds, the biggest difficulty is to increase the vulcanization speed of the rubber compound. In the domestic industry, no research and application in this area have been found after searching. Basically follow the previous process. [0003] Because the outsole of the 07 combat boots has requirements for flame retardant and oil resistance, and the use of neoprene rubber is clearly specified in the technical standards. Neoprene rubber has good flame retardant and oil resistance, but its proc...
