Abstract
The invention discloses a method for producing a CFT-PP cloth material by a melt-blown technology, which is suitable for the subsequent production of CFT-PP because the porosity, the thickness and the mechanical property of the prepared melt-blown cloth material are different by adjusting the formula composition of the cloth material. The cloth material prepared by the invention not only can meet the preparation requirement of CFT-PP, but also adopts the melt-blown technology to produce the cloth material, thereby solving the problems of greatly surplus production capacity, idle melt-blown machine and waste of the prior melt-blown cloth.
Description
Technical Field
The invention belongs to the technical field of production of Continuous glass fiber reinforced thermoplastic polypropylene (CFT-PP) sheets, and particularly relates to a glass fiber reinforced polypropylene material, a process technology, a preparation method and an application thereof.
Background
The glass fiber reinforced polypropylene is a sheet obtained by adding glass fiber into thermoplastic polypropylene resin, mixing and extruding through formula optimization and process optimization, and further performing die punch forming by using the sheet to obtain various special-shaped structural members, semi-structural members and non-structural members. In the glass reinforced polypropylene thermoplastic material, the length of the glass fiber is an extremely important parameter index, generally the length of the glass fiber is less than 3mm and is short glass fiber reinforced polypropylene thermoplastic material (SFT), the length of the glass fiber is 12-15 mm and is long glass fiber reinforced polypropylene material (LFT), the two have larger difference in mechanical properties, especially impact resistance, LFT-PP is higher than SFT, although the impact resistance of LFT-PP is still lower than that of steel, which limits the application of LFT-PP in certain products, such as front and rear bumpers of automobiles, especially front bumpers, the LFT-PP is not enough, and continuous glass fiber reinforced polypropylene (CFT-PP) is required to be used as a base material for compression molding processing. The general CFT-PP production methods include melt impregnation, solution impregnation, powder impregnation, fiber mixing and knitting, and the like. The melt impregnation method needs to adopt a cutting agent to reduce the molecular weight of PP so that the PP has lower melt viscosity and is convenient for impregnating glass fibers, obviously, the reduction of the molecular weight of PP greatly sacrifices the mechanical properties of PP, including impact resistance, bending resistance, tensile property and the like. The solution impregnation method needs to use a solvent, generally, the solvent capable of dissolving PP is very little, even if the solvent can be found, the PP needs to be dissolved at high temperature, the outstanding problem is that the solvent needs to be removed after the forming, the solvent removal process not only consumes a large amount of heat energy, but also causes environmental pollution and cost increase caused by the solvent, the material performance is reduced due to the residual solvent in the PP, and the release in use brings adverse effects on the body health of consumers. Although the powder impregnation method solves the defects of the former two methods, PP powder is needed, the finer the PP particles are, the better the impregnation effect is, but the PP particles are granules with the particle size of 2-3 mm when being delivered from a factory usually, the requirement on the source of raw materials is higher, the manufacturing cost is actually increased, and in addition, the mass ratio of the glass fiber and the PP is difficult to adjust freely. Glass fiber and PP fiber are required to be made into fibers with proper diameters respectively by mixed weaving, the glass and the PP are woven into mixed woven fiber cloth according to certain textures by weaving equipment, and then compression molding is carried out, so that higher requirements are provided for the preparation of the glass fiber and the PP fiber. How to realize efficient CFT-PP production is still a great challenge.
