Reprocessing process for waste sponge with negative ions

Abstract

The invention discloses a reprocessing process for waste sponge with negative ions. The reprocessing process comprises the following steps: (1) carrying out rough grinding, fine grinding and filtering on 100 parts of the waste sponge until the grain diameter is 20 meshes; (2) adding 25 to 30 parts of polyether and uniformly mixing; raising the temperature to 140 DEG C and heating for 2h; then cooling to 70 DEG C to 80 DEG C, and adding 25 parts of TDA (Toluenediamine); stirring for 30min to 60min at a stirring speed of 3000r / min; (3) adding 10 to 15 parts of negative ion powder and 13 to 14 parts of an adhesive, and mixing and stirring for 30min at a stirring speed of 3000r / min to 4000r / min; (4) carrying out die-casting molding through a die and heating at high temperature of 200 DEG C; after molding, de-molding to obtain finished-product sponge. According to the reprocessing process provided by the invention, the waste sponge is used as a raw material and the waste sponge is reprocessed to obtain new sponge; the new sponge can release a lot of the negative ions and the concentration of the negative ions is much higher than that of negative ions in the air; the sponge has health-care effects of sterilization, dust falling and the like and is more environment-friendly and safer; the waste sponge can be effectively utilized and the aim of reutilizing resources is realized; the cost can be saved.

Description

technical field [0001] The invention belongs to the technical field of sponge processing, in particular to a reprocessing process of adding anion components to waste sponges. The sponges produced by this method not only have the advantages of environmental protection, but also have high anion content and are beneficial to human health. . Background technique [0002] Sponge is widely used in home furnishing, clothing, shoe materials, packaging and other fields due to its low cost and dense pores. Waste sponges are old or discarded sponges formed during sponge production, processing or use. This waste sponge, only the leftover material of polyurethane type sponge just has 50,000-100,000 tons remaining every year, adds the waste and old sponge that produces because of excessive use and causes performance to drop and discard as scrapped, and its quantity is huge. If these discarded sponges are not recycled and reused, resources will be seriously wasted. But even if sponge is...

Or just re-crushing and reintegrating the waste sponge to form a new sponge, but the performance of this kind of sponge is lower than that of the first-time molding sponge, and its antibacterial and safety are difficult to be guaranteed.
