Abstract

The invention discloses a plasticizing additive for plastic. The plasticizing additive is prepared from the following components in parts by weight: 20 to 40 parts of urea solution, 12 to 20 parts of modified acrylic resin, 0.3 to 0.7 part of potassium carbonate, 0.01 to 0.03 part of cuprous chloride, 0.01 to 0.02 part of sodium methylate, 0.1 to 0.4 part of regulator, 0.02 to 0.03 part of nateglinide and 1 to 3 parts of potassium dihydrogen phosphate. By using the plasticizing additive for the plastic, which is provided by invention, the plasticity of the plastic can be effectively improved; the transverse and longitudinal tensile stress of the plastic is improved; thus, the plastic is enabled to have a better plasticization effect; further, the raw materials of the plasticizing additive are easily obtained; a preparation method is succinct and is easy to operate.

Description

technical field [0001] The invention belongs to the technical field of plastic processing, in particular to a plastic plasticizing additive. 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 plastic industry. Among the existing plastic plasticizing additives, 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 background of the present invention and shou...
