Foaming product using air to replace foaming agent and preparation method thereof

Abstract

The invention discloses a foaming product using air to replace a foaming agent and a preparation method thereof. The foaming product comprises the following raw materials in percentage by weight: 10-15% of soft butadiene styrene rubber, 15-20% of natural rubber, 5-10% of terpolymer, 15-20% of dioctyl phthalate, 20-30% of epoxy resin, 3-5% of polyvinyl butyral, 4-7% of azodicarbonamide, 5-15% of high-pressure low-density polyethylene and 1-3% of a cross-linking agent. According to the invention, air is adopted to replace a foaming agent in the prior art, a net structure of plastic or rubber is expanded, the foaming effect is achieved, the situation that a large amount of carbon dioxide is generated after foaming of the foaming agent, the environment is polluted is avoided, the foaming product does not have unpleasant smell, the epoxy resin is added, the bisphenol A epoxy resin in the epoxy resin has good physical and chemical properties after being cured, the product has good dimensional stability and high hardness, and meanwhile, the heat resistance of the foamed plastic is also improved.

Description

technical field [0001] The invention relates to the technical field of foamed products, more specifically to a foamed product in which air is used to replace a foaming agent and a preparation method thereof. Background technique [0002] In the foam molding process or foamed polymer material, a cellular or porous structure is formed through the addition and reaction of physical or chemical blowing agents. The basic steps of foam molding are the formation of nuclei, the growth or expansion of nuclei, and the stabilization of nuclei. Under given temperature and pressure conditions, the solubility of the gas decreases, so that it reaches a saturated state, so that the excess gas is removed and bubbles are formed, thereby achieving nucleation; the general term for making foam molding methods. [0003] At present, foam molding is mostly carried out by chemical methods. After the foaming agent is decomposed, a large amount of carbon dioxide will be generated, and the foaming agen...
