Abstract

The invention discloses an additive for improving plastic plasticity, which comprises the following components according to the ratio of parts by weight: 20-40 parts of potassium sulfate solution, and 12-20 parts of modified glycerin epoxy resin , 0.3-0.7 parts of sodium carbonate, 0.01-0.03 parts of ammonium chloride, 0.01-0.02 parts of methyl formate, 0.1-0.4 parts of regulator, 0.02-0.03 parts of nateglinide and 1-3 parts of potassium dihydrogen phosphate. The additive for improving the plasticity of the present invention can effectively improve the plasticity of the plastic, increase its transverse and longitudinal tensile stress, so that the plastic has a better plasticizing effect; further, the raw materials of the present invention are easy to obtain, and the preparation method is simple and easy. operate.

Description

technical field [0001] The invention belongs to the technical field of plastic processing, in particular to an additive for improving the plasticity of plastic. Background technique [0002] Plastics are mixed by raw materials, extruded into granules, and then made into various plastic products. Plasticization is the most important process in the plastics industry. Among the existing additives to improve the plasticity of plastics, phthalate plasticizers occupy a dominant position, with a market share of more than 50%. However, phthalate plasticizers have disadvantages such as high volatility and poor durability, and most phthalate plasticizers are toxic, so the scope of use is limited. Therefore, it is the demand of human progress and social development to seek a new formula and invent a plasticizer with excellent performance, non-toxic and harmless. [0003] The information disclosed in this Background section is only for enhancing the understanding of the general backgr...
