Embodiment 1

[0033] This embodiment provides 6 different modified graphene / polybutene composite masterbatch materials 1-6, which are prepared from the following raw materials in parts by weight.

[0034] Table 1

[0035]

[0036] Wherein, the composition and preparation method of the master batch material 4 and the master batch material 1 are basically the same, the only difference is that the raw material of the material 4 does not contain a nucleating agent.

[0037] The nucleating agent is dibenzylidene sorbitol, bis(p-methylbenzylidene) sorbitol, 2,2,- dimethylene bis(4,6-tert-butylphenol) phosphonate and its derivatives One of them, mixed with one of the diamide compounds, the preferred ratio of the two is (2-5:1), the structural formula of N,N'-bis(phenyl)glutaramide in the above embodiment is:

[0038]

[0039] In other embodiments, the diamide compound can also be selected from the general formula: R 1 -NH-C(O)-R-C(O)-NH-R 1 diamides.

Abstract

A modified graphene / polybutene composite masterbatch material according to the present invention is characterized in that it is prepared from the following raw materials: 0.1-40 parts of modified graphene; 80-120 parts of polybutene resin; 0.1-1.1 parts of agent; 0.2-1.2 parts of nucleating agent; 0.1-1.2 parts of dispersant. The composite material is applied to polybutene pipes, and polybutene pipes are prepared by simply adding modified composite material components, which can greatly improve the mechanical properties of polybutene pipes and make them have higher thermal conductivity It solves the problems of low heating efficiency and low comprehensive utilization rate of heat energy when polybutene pipes are used as heating pipes.

Description

technical field [0001] The invention belongs to the field of plastic pipes, in particular to a modified graphene / polybutene composite masterbatch material and its preparation method and application. Background technique [0002] Polybutene is a semi-crystalline polyolefin polymer with a linear molecular structure synthesized from 1-butene as a raw material under the action of a catalyst. It has excellent characteristics such as non-toxic and tasteless, acid and alkali resistance, solvent resistance, high and low temperature resistance, and compatibility with other high molecular polymers. It is also known as "plastic gold" because of its high price. In view of so many excellent properties of polybutene, it is widely used in piping materials for heating systems and hot water, drainage pipes, seals, compression packaging films and wires and cables for underground mining, etc. Although polybutene has so many excellent properties, it also has many shortcomings, such as its soft...
