Description
Technical Field
The invention belongs to the technical field of polypropylene drawing, and particularly relates to a filling master batch, a preparation method and application thereof, and a polypropylene drawing material containing the filling master batch.
Background
The polypropylene wiredrawing material is a common raw material of a plastic woven product, has excellent tensile property, and has the characteristics of no water absorption, corrosion resistance, no mildew, wear resistance, long service life and the like. In addition, the polypropylene wiredrawing material can also be used for producing color strip cloth, carpet backing (base cloth), flexible freight bags, tarpaulins and ropes.
The polypropylene wire drawing material mainly comprises polypropylene resin, filling master batch and auxiliary agent, wherein the commonly used filling master batch of the polypropylene wire drawing material is calcium carbonate filling master batch, and the calcium carbonate filling master batch is used for reducing the cost on one hand and improving the mechanical strength of polypropylene wire drawing on the other hand. In consideration of the influence of the filling master batch on the drawing mechanical property of polypropylene, high molecular weight polyethylene or polypropylene (with a melt index of about 2g/10 min) is generally used as a matrix resin, and because of the low melt flow rate, the processing needs to be added with a large amount of auxiliaries such as paraffin, stearic acid and the like so as to improve the processing fluidity of the filling master batch. However, in the polypropylene drawing process, the processing temperature is as high as 260 ℃, and auxiliaries such as paraffin, stearic acid and the like are decomposed and fuming at the temperature, so that a large amount of smoke is generated, and the environment and the health of workers are greatly influenced.
For example, CN 1935889a discloses a special material for polypropylene woven bag wire drawing, which comprises polypropylene resin, calcium carbonate, 168 antioxidant, BC1010 antioxidant, calcium stearate, stearic acid, special modifier and white oligomer sheet. CN 1966562A discloses a filling master batch for polypropylene drawing, which comprises superfine calcium carbonate, superfine talcum powder, homo-polypropylene, ethylene propylene rubber, ethylene-vinyl acetate copolymer wax, stearic acid and zinc stearate. Both use stearic acid to improve flow, which also entails fuming during drawing.
Therefore, how to improve the defect of fuming in the drawing process on the premise of ensuring the processing fluidity and the mechanical property of the polypropylene drawing material is a problem to be solved in the field.
