example 1
[0037] Step 1, take the waste polypropylene woven bag material accounting for 50% of the total weight, wash, chop, dry and set aside;
[0038] Step 2, 20% of the toughening modifier 1000 mesh mica powder, 5% of the toughening modifier ethylene-vinyl acetate copolymer (EVA), 0.6% of the activator titanate coupling agent, 0.4% lubricant dispersant polypropylene wax is put into a high-speed mixer heated to 180°C for stirring and kneading activation treatment and then used;
[0039] Step 3, put the ready-to-use material processed in step 1 and step 2 into a mixer and stir evenly with 4% of the total weight of the phosphite lipid antioxidant and 20% of the new polyolefin material;
[0040] Step 4. Stir and mix the materials evenly and put them into a screw drawing machine for heating. When the temperature is heated to 220°C, wire drawing is carried out to produce finished woven bag materials.

Abstract
The invention provides a regenerated wire drawing modified material of waste polypropylene woven bags, comprising the following components in percentage by weight: 1-35 percent of polyolefin fresh material, 25-95 percent of waste polypropylene material, 1-55 percent of enhanced modifier, 1-30 percent of toughening modifier, 0.01-5 percent of activator, 0.1-3 percent of antioxidant, 0.01-6 percent of lubricant and 0.01-6 percent of dispersing agent. The invention also provides a preparation method of the regenerated wire drawing modified material of the waste polypropylene woven bags. In the preparation method, based on the arecovery treatment on the waste polypropylene woven bags, the new wire drawing modified material of woven bags are produced by adding proper amount of other raw materials and auxiliary materials and can be directly used for producing polyolefine flat fibers with stable performance. The performance of a new polypropylene woven tape produced from the prepared material and a small quantity of fresh material is equivalent to a woven bag wholly produced by carrying out granulation and wire drawing on the fresh material. The new polypropylene woven tape can completely satisfy the use performance requirements, dramatically lower the product production cost and provide a proper way for waste recycling utilization and environmental pollution reduction.
Description
technical field [0001] The invention belongs to the technical field of chemical engineering and environmental protection, and relates to a polyolefin woven material enhancement modification technology, in particular to a regenerated drawing modification material for waste polypropylene woven bags and a preparation method thereof. Background technique [0002] my country's annual waste of nearly 3 million tons of woven bags is called white pollution, just like the agricultural film that is difficult to degrade naturally. At present, waste woven bag recycled wire drawing factories basically only use simple cleaning, then chop up, and melt, extrude and granulate through a spiral heating extruder with water in the recycling process of waste woven bags, without any process. modification treatment. Firstly, this method consumes part of the original additives in the waste polypropylene woven bag, and the heating method with water will further age and carbonize the plastic. In addi...
