Problems solved by technology

Due to the inconsistent quality and practical standards of various products on the market, it has caused great inconvenience to the woven bag production industry
In addition, the existing various raw and auxiliary materials are mixed by manual mixing. Manual mixing causes uneven mixing, product quality decline, and dust generated during mixing pollutes the environment; moreover, it consumes a lot of manpower, material resources and electric energy, which increases production costs.

Abstract

The invention relates to polypropylene woven bag wire drawing special material. Its preparing method includes the following steps: adding calcium carbonate, special modifier, white low molecular polymer sheet and stearic acid into stirrer at normal temperature; discharging the activated inorganic filling agent from feed opening to do bagging reserve; adding the above matter, acrylic resin, white low molecular polymer sheet, BC1010 antioxidant, 168 antioxidant, calcium stearate into mixer to stir; discharging the mixed material to store in holding hopper; putting the above matter into extruder to de fusion and mixing; extruding by extruder; sending to dicer cutter through quench bath and air dryer to cut into cylindrical particle with 3*3 norms. The products have the advantages of high intensity, good processing property, low static electricity, low dust, and saving manpower, material resources, and reducing the production cost.

Description

technical field [0001] The invention belongs to plastic braiding materials, and in particular relates to a special material for wire drawing of polypropylene woven bags and a preparation method thereof. Background technique [0002] At present, the weaving industry generally uses PP powder or granules as raw materials, and then purchases inorganic filler masterbatch and various auxiliaries from the market for mixing and then knitting and knitting. Due to the inconsistent quality and practical standards of various products on the market, it has caused great inconvenience to the woven bag production industry. In addition, the existing mixing of various raw and auxiliary materials all uses manual mixing, which causes uneven mixing, lowers product quality, and pollutes the environment with dust generated during mixing; moreover, it consumes a lot of manpower, material resources and electric energy, which increases production costs. Contents of the invention [0003] The main ...
