Abstract

The invention relates to the technical field of beta nucleating agent master batches, and discloses a long-chain branched PPH loaded beta nucleating agent master batch, which is prepared from the following components in parts by weight: 70 to 80 parts of PP resin, 10 to 28 parts of PPH resin, 1-2 parts of beta nucleating agent, 3 to 5 parts of stearic acid and 0.1 to 0.3 part of antioxidant. According to the long-chain branched PPH loaded beta nucleating agent master batch, by utilizing the reinforcing function of the long-chain branched PPH and the toughening function of the beta crystal, thetoughness and ductility of the prepared PP composite material are obviously improved while the strength of the PP composite material is maintained.

Description

technical field [0001] The invention relates to the technical field of β-nucleating agent masterbatch, in particular to a long-chain branched PPH-loaded β-nucleating agent masterbatch and a preparation method thereof. Background technique [0002] As one of the five general-purpose plastics, polypropylene (PP) has good processing, mechanical and chemical resistance properties, and is widely used in home appliances, automobiles, and electronics. However, PP also has shortcomings, especially poor toughness, which greatly limits the application field of PP. Therefore, the modification of PP has important theoretical significance and broad commercial space. Polypropylene is a polymorphic polymer with crystal forms such as α, β, γ, δ and pseudohexagonal crystals. Among them, compared with ordinary α-crystalline PP, β-crystalline PP not only maintains the good comprehensive properties of α-crystalline PP, but also has several times the impact strength of α-crystalline PP, and it...
