Problems solved by technology

However, because polypropylene is a non-polar polymer, the low-temperature performance and aging resistance of homopolymer are also poor, and the molding shrinkage rate is large, which limits the further development and application of polypropylene.

Abstract

The invention discloses a flame retardant polypropylene modified resin. The flame retardant polypropylene modified resin is prepared by using the following raw materials, by weight, 80-110 parts of PP, 10-20 parts of chlorinated polypropylene, 2-4 parts of polyethylene terephathalate, 40-56 parts of modified PP, 2-3 parts of polycarbonate, 1-2 parts of stearic acid, 0.01-0.3 parts of an antioxidant 1076, 0.1-0.3 parts of butyl benzyl phthlate, 0.3-0.5 parts of tributyl citrate, 0.3-0.5 parts of zinc naphthenate, 0.2-0.4 parts of magnesium naphthenate, 1-2 parts of a silane coupling agent KH550 and 50-55 parts of a compound flame retardant. The flame retardant polypropylene modified resin prepared in the invention has a good flame retardation property and excellent mechanical performances, and the cooperation of the modified PP and the compound flame retardant can realize a good flame retardation property.

Description

technical field [0001] The invention relates to the field of polypropylene rods, in particular to a flame-retardant polypropylene modified resin and a preparation method thereof. Background technique [0002] Substituting plastic for steel and plastic for wood has become a trend in material development. At present, the materials that mainly replace steel (or copper, alloy) and other metals on the market are mainly engineering plastics such as nylon (PA); nylon (PA) has good toughness, strong wear resistance, oil resistance, shock resistance, tensile and bending strength. . Therefore, it is widely used to process various wear-resistant high-strength parts, instead of copper and alloys as wear-resistant parts of equipment. However, because nylon itself is easy to absorb water, has poor light resistance, poor dimensional stability, and is relatively expensive, it greatly hinders the application range of nylon rods. [0003] As one of the five general-purpose plastic material...
