Abstract

The invention discloses a master batch of plastic products, in particular to a polymer for PP-R high polymer. The polymer for PP-R high polymer comprises the following raw materials according to the parts by weight: 55-75 of calcium carbonate, 1-3 of lubricant, 0.3-0.8 of polyethylene wax, 0.3-0.8 of polypropylene wax, 5-15 of polyethylene, 3-8 of polypropylene, 1-5 of coupling agent, 0.5-2.5 of zinc stearate, 1-3 of stearic acid and 5-15 of talcum powder. The polymer for PP-R high polymer of the invention fills the gap of the field; the invention has large filling volume, and the original physical properties of the polymer can be kept after being filled; the invention is characterized by high strength and toughness, good sizing and the like and the cost of the manufacturers of PP-R products can be largely decreased. Under the current situation of energy scarcity, a great amount of energy can be saved.

Description

technical field [0001] The invention relates to a masterbatch of plastic products, in particular to a polymer for PP-R macromolecule. Background technique [0002] At present, PP-R special plastic masterbatch is still blank, and the price of other plastic masterbatch raw materials has been high, so PP-R modified plastic masterbatch products have remained high. The existing plastic masterbatch has a small amount of filling, and any kind of filling will have an impact on product quality, and there is no way to improve such a situation at present. Moreover, the strength of the existing plastic masterbatch is low, and the toughness needs to be further improved. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a polymer for PP-R polymer, which has large filling capacity, low cost, high strength, increased toughness, good shaping, and can save a lot of energy. toxic free and safe. [0004] In order to solve the ...
