Abstract

The present invention relates to a reinforced polypropylene plastic glass fiber sizing agent, the sizing agent is composed of the following components, and the mass usage percentage of each component to the total mass of the sizing agent is expressed as follows: (1) acrylic acid emulsion 3-22%; (2) Polyvinyl acetate emulsion 2‑24%; (3) Polyester emulsion 1‑10%; (4) Epoxy emulsion 1‑17%; (5) Modified aliphatic hydrocarbon lubricant 0.1‑3.5%; (6) Silane coupling agent 0.2-1.5%; (7) Surfactant 0.1-2%; (8) Antistatic agent 0.1-1.0%; (9) pH regulator 0.1-0.9%; (10) The remainder is Deionized water. Compared with the prior art, the sizing agent provided by the present invention has good compatibility with polypropylene plastic resin, enhances the plasticity and stiffness of glass fiber, reduces the generation of fuzz, and has good cutting performance, dispersibility and fluidity And endow the composite material with outstanding mechanical and electrical properties, while improving the mechanical properties of the glass fiber.

Description

technical field [0001] The invention belongs to the field of glass fiber sizing, in particular to a reinforced polypropylene plastic glass fiber sizing. Background technique [0002] As one of the four general-purpose plastic materials, polypropylene plastic has excellent comprehensive properties, good chemical stability, good molding performance and relatively low price; but it also has low strength, modulus, hardness, and resistance to Poor low temperature impact strength, large molding shrinkage, easy aging and other disadvantages. Therefore, it must be modified so that it can be adapted to the needs of the product. The modification of polypropylene plastic materials is generally through adding minerals to enhance toughness, weather resistance modification, glass fiber reinforcement, flame retardant modification and super tough modification. have a large number of applications. As far as reinforcing fibers are concerned, glass fibers are currently the most used and mos...
