Abstract

The invention discloses a high-performance rotational molding product cross-linking foaming forming process which comprises the following steps: S1, selecting a mold, namely selecting a required mold, forming a material placing space in the mold, opening the upper part of the mold, and fixing the mold in a heating chamber; s2, the plastic plate is smashed and ground through a grinding machine, and plastic powder is obtained through grinding for standby application; s3, the plastic powder in the S2 is guided into the material containing space in the mold in the S1, the mold is closed, the peripheral wall of the mold is fixed, and a feeding notch is formed in the upper portion of the mold; and S4, the temperature in the heating chamber in the step S1 is increased to 40-50 DEG C, a stabilizer and a catalyst are added into a feeding notch in the upper portion of the mold in the step S3, stirring is conducted through a stirring machine till the stabilizer and the catalyst are completely fused with the plastic powder, and the time is controlled to be 10-15 min. A special rotational molding product forming process is utilized, and the product is high in impact resistance, toughness and plasticity, has high temperature resistance and is convenient to operate, so that rotational molding is simple and easy to implement.

Description

technical field [0001] The invention relates to the technical field of preparation of rotationally molded products, in particular to a high-performance crosslinked foaming molding process of rotationally molded products. Background technique [0002] The molding process of rotational molding products is to add plastic raw materials (powder) into the mold, and then, the mold is continuously rotated along two vertical axes and heated, so that the plastic raw materials in the mold are gradually and evenly coated under the action of gravity and heat. Cloth, melted and adhered to the entire surface of the mold cavity, shaped into the required shape, then cooled and shaped, demoulded, and finally the product was obtained. Rotational molding (also called selective molding or rotary molding) technology was developed in Europe in the 1950s, and later spread to the United States, Japan and other places. At first, this molding technology only used liquid PVC paste resin as raw material...
