Embodiment 1

[0013] 60 parts of PVC material, 8 parts of DOP, 10 parts of compound flame retardant plasticizer of dialkyl tetrachlorophthalate and dialkyl tetrabromophthalate, composite flame retardant (including 6 parts of boron-containing flame retardant): 18 parts, 0.5 parts of stabilizer, 1.5 parts of lubricant, mixed evenly at 80°C, and finally added 2 parts of foaming agent, mixed evenly, and then sent to twin-screw extrusion Extrude and granulate in the machine, the granulation temperature is 135°C, and then the pellets are dried and then injection molded in the injection molding machine. The material LOI was measured to be 35% and the density was 0.75.

Embodiment 2

[0015] 70 parts of PVC material, 8 parts of DOP, 5 parts of triphenyl phosphate, 12 parts of antimony and metal-based oxide flame retardant, 1.0 part of stabilizer, 1.0 part of lubricant, mix well at 80 °C, and finally add 3 parts of foaming agent are mixed evenly, and then sent to a twin-screw extruder for extrusion and granulation. The granulation temperature is 135° C., and then the granules are dried and then injected into an injection molding machine. The material LOI was measured to be 32% and the density was 0.68.

Embodiment 3

[0017] 75 parts of PVC material, 11 parts of DOP, 5 parts of triphenyl phosphate, 5 parts of antimony-containing flame retardant, 0.5 parts of stabilizer, 1.5 parts of lubricant, mix well at 80°C, and finally add 2 parts of foaming agent Mix evenly, and then send it to a twin-screw extruder for extrusion and granulation. The granulation temperature is 135° C., and then the pellets are dried and then injected into an injection molding machine. The material LOI was measured to be 30% and the density was 0.70.

Abstract

The invention discloses a novel flame-retardant low-density foamed PVC shoe sole material, which consists of the following components in terms of weight percentage: PVC: 60%-75%; DOP: 8%-20%; flame-retardant plasticizer: 5%‑15%; composite flame retardant: 5%‑20%; stabilizer: 0.5%‑2.0%; lubricant: 0.8%‑1.5%; blowing agent: 2.0%‑3.0%. Compared with the prior art, the present invention has the advantages of good flame retardant effect, good foaming effect and low density.

Description

Technical field: [0001] The invention relates to the technical field of shoe materials, in particular to a PVC shoe sole material. Background technique: [0002] Polyvinyl chloride (PVC) materials are widely used in China. Due to its low cost, PVC has an irreplaceable position in the field of shoe materials. However, at present, PVC shoe materials have problems such as high density, heavy wearing, and poor flame retardancy. In some special industries such as fire protection, there are higher requirements for the flame retardant performance of PVC shoe materials. Existing this flame-retardant low-density foamed PVC shoe material on the market at present. Invention content: [0003] The technical problem to be solved by the invention is to provide a flame-retardant low-density foamed PVC shoe sole material. [0004] In order to achieve the above object, a kind of flame-retardant low-density foamed PVC sole material of the present invention is made of following components ...
