Processing technology for producing flame-retardant granular material by utilizing waste textile fibers

Abstract

The invention discloses a processing technology for producing a flame-retardant granular material by utilizing waste textile fibers. The processing technology comprises the following steps: S1, removing particles and impurities in the waste textile fibers; S2, cleaning the waste textile fibers in the step S1 with clean water; S3, cleaning the waste textile fibers obtained in the step S2 with clearwater, and dehydrating and drying the waste textile fibers; S4, hardening the textile fibers; S5, grinding the hardened waste textile fibers into powder; S6, mixing the crushed waste textile fiber powder, calcium carbonate powder, an antioxidant, a plasticizer, a catalyst, glass fibers, a dispersing agent, a coloring agent, a stabilizer and a flame retardant; and S7, premixing the materials in the step S6 through a high-speed mixer, adding the mixed materials into a screw extruder, mixing the materials, and cutting the mixture into granules. In the invention, the processing technology is green and environment-friendly, resources are saved, the preparation method is simple, the cost is low, and the screw extruder used in the processing process can improve the granulation efficiency of theflame-retardant particles.

Description

technical field [0001] The invention relates to the technical field of processing flame-retardant granular materials, in particular to a processing technology for producing flame-retardant granular materials by utilizing waste textile fibers. Background technique [0002] In recent years, along with the rapid development of the economic and technological level and the great enrichment of people's social and material life, more and more waste textile fibers are produced in people's production and life, and most of the waste textile fibers have not been effectively recycled. And reuse, the shelving and random discarding of waste textile fibers can easily lead to a huge waste of resources and serious environmental pollution. In order to reduce environmental pollution, waste textile fibers can be used to prepare flame-retardant granular materials. [0003] With the advancement of science and technology and the improvement of living standards, polymer materials, especially synthe...
