Problems solved by technology

[0008] The present invention aims to overcome the problem that the antistatic masterbatch in the prior art causes the decomposition of amine substances in plastic products during high-temperature processing due to amine substances, which causes the plastic products to produce peculiar smell, and the types of additives added in the masterbatch preparation process are relatively large. Many, complicated process, increased process cost and other disadvantages, to provide an amine-free antistatic compound that enables plastic products to have high gloss and low haze while having good comprehensive properties and excellent antistatic properties, and meets the needs of food packaging Material

Embodiment 1

[0023] The weight component of mixed raw material is as follows:

[0024] Polypropylene: 90%;

[0025] Glyceryl distearate: 3%;

[0026] Sorbitan monolaurate: 4%;

[0027] Polyethylene oxide (20) glyceryl monostearate: 3%.

[0028] Put the above-mentioned raw materials into a high-speed mixer in proportion for mixing, and then use a twin-screw extruder to granulate. Material.

[0029] The amine-free antistatic composite material prepared above was used on BOPP film to produce film 1, and the same amount of imported antistatic agent (model: ASPA2556, manufacturer: Schulman (Dongguan) Plastic Co., Ltd.) was added. BOPP film (control sample 1) was compared for electrostatic half-life.

[0030] Test standard: GB / T 14447-1993 Electrostatic test method of plastic film half-life method;

[0031] Test instrument: electrostatic tester;

[0032] Model: H-0110V-1

[0033] Manufacturer: Shanghai Guangshang Electronic Technology Co., Ltd.

[0034] The results of the BOPP f...

Embodiment 2

[0037] The weight component of mixed raw material is as follows:

[0038] Polypropylene: 80%;

[0039] Glyceryl monostearate: 4%;

[0040] Sorbitan monostearate: 7%;

[0041] Polyethylene oxide (5) glyceryl monostearate: 9%.

[0042] The granulation method, testing method, testing equipment of amine-free antistatic composite material, the imported antistatic agent of the same amount that control sample 2 adds are identical with embodiment 1, and the result of the BOPP film that is made is as follows as in sample 2 test:

[0043]

Embodiment 3

[0045] The weight component of mixed raw material is as follows:

[0046] Polypropylene: 75%;

[0047] Glyceryl monostearate: 10%;

[0048] Sorbitan monooleate: 6%;

[0049] Polyethylene glycol fatty acid esters: 9%.

[0050] The granulation method, test method, test equipment, and the imported antistatic agent of the same amount added by the amine-free antistatic composite material in the control sample 3 are the same as in Example 1, and the results of the BOPP film made and the same 3 tests are as follows:

[0051]

[0052] As can be seen from Table 1, Table 2 and Table 3, the electrostatic half-life of the non-amine antistatic composite material of the present invention is shorter than that of imported antistatic agents, and the film produced by the composite material of the present invention does not use amine antistatic agents, There is no peculiar smell, and the application range of the film can be expanded, especially for export food packaging.

Abstract

The invention discloses an amine-free antistatic composite material, of which the heat resistance temperature is 300-350 DEG C and the volatility is less than or equal to 3%. The amine-free antistatic composite material is prepared by mixing 70-90 wt% of polypropylene and 10-30 wt% of antistatic agent, wherein the antistatic agent is prepared by mixing a component A glyceride, a component B sorbitan ester and a component C polyester; and the component A accounts for 3-15 wt% of all the raw materials, the component B accounts for 4-15 wt% of all the raw materials, and the component C accounts for 3-15 wt% of all the raw materials. The three amine-free nonionic antistatic agents are scientifically compounded to overcome the defects when an individual component is in use in certain cases and prevent the plastic product from generating peculiar smells due to decomposition of the antistatic agent caused by high temperature in the working process; and meanwhile, the plastic product still has a stable migration rate, so that the antistatic system performs an enduring effective function, thereby ensuring the continuous and stable antistatic capacity of the plastic product, and widening the application range of the film. The amine-free antistatic composite material especially can be used in exported food packages.

Description

technical field [0001] The invention relates to an antistatic composite material, in particular to an amine-free antistatic composite material used in the production of various plastic products such as polypropylene. Background technique [0002] In recent years, the share of my country's exported food, food packaging and contact materials in the international market has been increasing year by year. However, most food export companies do not know much about a series of new laws and regulations issued abroad or have not paid enough attention to them. Some export food companies only pay attention to the safety and quality of the food they produce, but do not pay attention to the safety and quality of the packaging they use. More and more food is banned from entering the country, returned and destroyed because the packaging does not meet the regulations and standards of some developed countries. Although the increasingly stringent new requirements and standards put forward...
