Embodiment

[0011] A kind of anti-scorch white apron glue for sports shoes, calculated by weight, comprising:

[0012] Standard rubber 70-90, butadiene rubber 10-30, ultramarine 1.3-1.5, zinc oxide 4-6, stearic acid 1-3, white carbon black 15-25, titanium dioxide 40-50, accelerator M 0.4-0.6 , accelerator DM 1.6-1.8, accelerator D 0.1-0.2, antioxidant SP-C 1-3, sulfur 1.6-2.0, industrial grease 4-8, RX-80 resin 6-8, calcium carbonate 80, salicylic acid 0.3-0.5.

[0013] The formulation can be completed by two-stage mixing with an internal mixer to improve the adhesiveness of the compound.

[0014] Standard rubber is 3L standard rubber, and the total content of standard rubber and butadiene rubber is 100 parts by weight.

[0015] Specifically, a kind of non-scorch white apron glue for sports shoes, calculated in parts by weight, includes:

[0016] 3L standard rubber 80, butadiene rubber 20, ultramarine 1.4, zinc oxide 5, stearic acid 2, white carbon black 20, titanium dioxide 45, accele...

Abstract

The invention discloses a sport shoe white foxing rubber resistant to scorching. The foxing rubber is characterized by being composed of the following components in parts by weight: 70 to 90 parts of standard rubber, 10 to 30 parts of cis-butadiene rubber, 1.3 to 1.5 parts of ultramarine, 4 to 6 parts of zinc oxide, 1 to 3 parts of stearic acid, 15 to 25 parts of white carbon black, 40 to 50 parts of titanium dioxide, 0.4 to 0.6 part of promoter M, 1.6 to 1.8 parts of promoter DM, 0.1 to 0.2 part of promoter D, 1 to 3 parts of anti-aging agent SP-C, 1.6 to 2.0 parts of sulfur, 4 to 8 parts of industrial grease, 6 to 8 parts of RX-80 resin, 80 parts of calcium carbonate, and 0.3 to 0.5 part of salicylic acid. The white foxing rubber has the advantages that salicylic acid is added to prevent the phenomenon of scorching, the foxing rubber is resistant to scorching, and thus the safety of rubber processing is largely improved.

Description

technical field [0001] The invention relates to the field of rubber material preparation, relates to the formula of side glue for shoes, in particular to a white skirt glue for sports shoes which is not easy to scorching. Background technique [0002] Scorching is a phenomenon of early vulcanization of rubber materials. The reasons for scorching are: improper coordination, such as too much vulcanizing agent and accelerator; improper operation, such as too high roller temperature, premature addition of sulfur, or The mixing time is too long. Uneven mixing causes local concentration of vulcanizing agents and accelerators; improper cooling and parking of rubber materials. If it is parked for too long, the temperature of the parking place is too high or the air is ventilated, etc., when scorching occurs, the surface of the rubber material is not smooth, and the plasticity of the pockmarked surface is reduced. In severe cases, particles of different sizes will appear on the surf...
