Effect test

Embodiment 1

[0033] Weighing: 4 kg of cedarwood oil, 6 kg of chitosan, 15 kg of nano-titanium dioxide, 20 kg of nano-silver oxide, 40 kg of polyhexamethyleneguanidine phosphate, and 3 kg of polyhexamethyleneguanidine hydrochloride. Stir and mix evenly to obtain a compound antibacterial agent.

Embodiment 2

[0035] Each raw material was weighed according to the data corresponding to Example 2 in Table 1. Mix the components uniformly in a mixer at a speed of 300-400r.p.m, mix for 5-10 minutes, then melt and knead in a twin-screw extruder, extrude and granulate, and extrude the extruded pellets at 90°C Dry it in a constant temperature oven for 9 hours, then inject it into a 50mm×50mm plastic sample at an injection molding temperature of 200-220°C, and conduct an antibacterial test. The test data are shown in Table 2. Antibacterial test standard: QB / T2591-2003A "antibacterial plastic antibacterial performance test method and antibacterial effect". Detection bacteria: Escherichia coli (Escherichia coli) ATCC25922, Staphylococcus aureus (Staphy lococcus aureus) ATCC6538.

Embodiment 3

[0037] Each raw material was weighed according to the data corresponding to Example 3 in Table 1. Plastic samples were prepared according to the method of Example 2, and then antibacterial tests were carried out.

Abstract

The invention discloses an antibacterial nylon-6 plastic, which comprises the components in parts by weight as follows: 100 parts of nylon-6 and 0.3-0.5 parts of a compound antibacterial agent. The compound antibacterial agent comprises the components in parts by weight as follows: 2-6 parts of cedar wood oil, 4-8 parts of chitosan, 10-20 parts of nanometer titania, 15-25 parts of nano silver oxide, 30-50 parts of polyhexamethylene guaidine phosphate and 2-4 parts of polyhexamethylene guaidine hydrochloride. The antibacterial nylon-6 plastic has a broad-spectrum antibacterial effect, as well as effects of inhibiting bacteria powerfully, killing bacteria and proofing mildew, and can be applied to the production of a connector, a wire reeling shaft, a timer, a protecting cover breaker, a switch casing base, a cooling fan for an automobile, a door handle, an oil tank cover, a gas inlet grid, a water tank protective cover, a lamp base and the like.

Description

technical field [0001] The invention relates to an antibacterial plastic, in particular to an antibacterial nylon 6 plastic. Background technique [0002] There are various kinds of microorganisms in nature. In daily life, microorganisms are closely related to people. However, some bacteria, fungi, viruses, etc., as pathogenic bacteria, seriously endanger human health and even life. According to statistical data, the number of deaths due to bacterial infection in the world is close to 20 million every year, accounting for about 30% of the total number of deaths; in 1996, the statistics of the "WHO" magazine in the United States showed that in 1995, about 52 million people died in the world, of which About 17 million died due to bacterial infection. These diseases mainly include cholera, pneumonia, malaria, tuberculosis and hepatitis. As we all know, the "mad cow disease" that broke out in the United Kingdom in the past ten years, the "foot-and-mouth disease" that appeared ...
