Environment-friendly foaming material taking OBSH as foaming agent and preparation method thereof

Abstract

The invention relates to an environment-friendly foaming material taking OBSH as a foaming agent and a preparation method thereof. The environment-friendly foaming material is prepared from the following components: 100 weight parts of base materials, 20-60 weight parts of OBSH foaming agent, 0.4-5.9 weight parts of cross-linking agent and 0.5-3 weight parts of zinc stearate, wherein 4,4'-oxybis (benzenesulfonyl hydrazine) is served as the OBSH foaming agent; triallyl isocyanurate is served as the TAIC cross-linking agent; bi-tertiary butyl peroxide diisopropyl benzene is served as the BIPB cross-linking agent. The invention also provides the preparation method for the foaming agent. The environment-friendly foaming material and the preparation method thereof have the advantages that the formula is reasonable; the primary foaming temperature is controlled at 120-149 DEG C and the steam pressure is 0.2-0.47Mpa; the multiplying power for the first foaming is controlled within 1.2-1.8 times; the primary foaming is controlled under the three parameter conditions, so that the OBSH cross-linking agent can effectively prevent adverse reaction with the cross-linking agent and the technology for producing the environment-friendly foaming material is stable.

Description

technical field [0001] The invention relates to a foaming material manufacturing technology, in particular to an environmentally friendly foaming material using OBSH as a foaming agent and a preparation method thereof. Background technique [0002] PE, EVA, TPE, POE and other thermoplastics and thermoplastic elastomers and materials modified with rubber, by adding AC (azodicarbonamide) foaming agent, cross-linking agent, foaming aid, lubricant, flame retardant Agents and other functional additives can be made into various sporting goods, toys, luggage materials, shoe materials, thermal insulation and other materials through kneading, kneading or extrusion, primary foaming, and secondary foaming in sequence. , is widely used, and its technology is mature, but because the AC foaming agent is used in the above-mentioned primary foaming and secondary foaming, the resulting product has a relatively strong ammonia smell, and its decomposition product formamide is an unfriendly mat...
