Processing method of composite plastic materials for high-toughness building templates

The invention relates to a processing method of composite plastic materials for high-toughness building templates. The processing method comprises the following steps: mixing and granulating a mixture of rubber and additives to obtain a rubber-modified material, and then carrying out melt blending on the rubber-modified material and plastic particles. The processing method has the advantages that on one hand, the liquid or solid additives can be effectively mixed with rubber and enter the rubber after being mixed to enable the network structure in the rubber to be fully relaxed, so that the processing fluidity, the compatibility and the dispersing uniformity of the rubber when being subjected to melt blending with the plastic particles are improved and further the toughness of the composite plastic materials is further improved; on the other hand, the rubber-modified material is large-particle-shaped, cannot cause pollution to a production workshop for melt blending of the rubber-modified material and the plastic particles and also cannot cause hazard to related operators; in addition, since the additives are uniformly dispersed inside the rubber-modified material and the internal network structure is fully relaxed by mixing, the melt blending effects of the rubber-modified material with the plastic particles also cannot be influenced even though the rubber-modified material is the large particle material.
