Problems solved by technology

[0004] The slush plastics produced are often used as car dashboards, slush plastic toys, etc. During use, the main thing that affects the user experience is the softness of the slush plastics. Most of the slush plastics currently on the market are not flexible enough, resulting in poor user experience and use effects not good

Abstract

The invention relates to the technical field of slush molding, in particular to a formula of a slush molding material, which is realized by the following technical scheme: the slush molding material mainly comprises the following raw materials in percentage by weight: 21.6-22.5% of dioctyl terephthalate; 2.8 to 3.3 percent of a PVC (Polyvinyl Chloride) viscosity reducer; 3% to 4% of DNTXIB; 1-1.5% of hot oil; 1.8%-2.2% of phenol-free calcium zinc; 0.1 to 0.3 percent of dimethyl silicone oil; 30 to 40 percent of PVC (Polyvinyl Chloride) paste resin; 8 to 13% of PVC paste resin; according to the present invention, the sum of the percentages of all the components is 100%, and the raw materials and the corresponding proportions are matched for use, such that the produced slush molding material has characteristics of no toxicity, good weather resistance, strong stability, color fading resistance, good flexibility, smooth and beautiful surface and easy demolding, and the quality of the slush molding product is ensured.

Description

Technical field [0001] The present invention relates to the field of plastic plastic technology, and in particular, to a formulation of a plastic mold. Background technique [0002] Polyvinyl chloride is a thermoplastic with excellent performance, soft polyvinyl chloride epidermal has a characteristics of light, soft, like leather-like surface and clear surface texture, and low cost, which usually uses a plastic molding method. The plastic powder used is a polyvinyl chloride resin, a plasticizer, a heat stabilizer, an antioxidant, a pigment, and the like. [0003] The plastic process is one of the best, most commonly processed methods, and the process flow is approximately the mold to heat the mold to a certain temperature, use the free flow of the plastic powder, carry out a plastic molding, through rotation, make the plastic The powder is adhered to the inner surface of the hot mold; the mold with a plastic powder is further heated, so that the plastic powder is melted; then co...
