Problems solved by technology

During the use of the air conditioner, the surface material is easily contaminated by oil, fingerprints, etc., which is difficult to remove, and under warm and humid conditions, microorganisms in the air are easy to attach and multiply on the surface
For the internal structure of the air conditioner, such as the air duct, dust and microorganisms in the air are easy to adhere, reproduce and deposit on the surface of the air duct. Since the internal unit is difficult to disassemble and clean, after long-term use, the interior of the air duct will seriously accumulate dust, affecting the air volume, noise and Energy efficiency, after stopping and restarting, the dust and microorganisms on the surface may fall off, which will produce peculiar smell, form secondary pollution, and affect air quality

preparation example Construction

[0043] According to an embodiment of the present invention, the preparation method includes: (1) mixing a resin substrate, a dispersant, an antioxidant, an antibacterial agent, and a fluorine-containing surface modifier to obtain a raw material mixture; (2) using an extruder to The raw material mixture is subjected to an extrusion process to obtain a plastic material.

[0044] In the preparation method, the resin base material and various additives are pre-mixed, and then the molding processing method of blending, extrusion and granulation is adopted, so that a plastic material with good mechanical properties, low surface energy and reprocessing performance can be obtained. The inventors of the present invention have found that the pre-mixing of raw materials can promote the uniformity of plastic materials; and by means of an extruder, each component can be fully mixed in a molten state, so that a plastic with high mechanical properties and low surface energy can be obtained. ...

Embodiment 1

[0057] In this example, a modified copolymerized PP plastic material was prepared. Specifically, the formula is shown in Table 1.

[0058] Table 1. Raw materials and proportions of copolymerized PP plastic materials (mass fraction unit: %)

[0059]

[0060] According to the above formula ratio, the components are mixed and stirred evenly, and then added to the hopper of the extruder. All the components are heated, sheared and mixed by the extruder, plasticized into a uniform melt, cooled and pelletized after passing through the die, Get the required plastic material. Wherein, the temperature range of each section of the extruder is 170-220°C.

Embodiment 2

[0066] In this example, with reference to GBT 17037.1-1997, the copolymerized PP plastic materials prepared in Example 1, Comparative Example 1 and Comparative Example 2 were injection-molded, and the obtained samples were subjected to mechanical performance tests, antibacterial and mildew-proof tests, and surface tests. Performance testing and ease-of-cleaning trials.

[0067] Specifically, mechanical performance tests include tensile, bending and impact tests. Among them, the tensile performance is carried out according to GB / T1040.2-2006, the bending performance is carried out according to GB / T 934-2008, and the impact performance is carried out according to GB / T 1843-2008. The antibacterial test and mildew test are carried out according to GB 21551.2-2010, and the antibacterial rate is tested according to the film method. Surface performance testing, using the method of measuring the contact angle between the surface of the material and water. Easy-to-clean test: take a ...

Abstract

The invention provides a plastic material, and a preparation method and an application thereof. The plastic material comprises a resin substrate, a dispersing agent, an antioxidant, an antibacterial agent and a fluorine-containing surface modifier. The fluorine-containing surface modifier and the antibacterial agent are simultaneously added into the plastic material provided by the invention, wherein the fluorine-containing surface modifier can effectively reduce the surface energy of the plastic material, so that dust, microorganisms and other dirty matters are difficult to attach to the surface of the plastic material, and meanwhile, the antibacterial agent can immediately restrain or kill the attached microorganisms and the antibacterial agent and the fluorine-containing surface modifier can synergistically achieve the anti-microbial, stain-resisting and easy cleaning effects.

Description

technical field [0001] The invention relates to the field of household appliance materials, in particular, the invention relates to plastic materials and their preparation methods and applications. More specifically, it relates to plastic materials, methods for preparing plastic materials, plastic parts and household appliances. Background technique [0002] At present, as a material that is easy to form, light in weight, high in specific strength and good in decoration, plastic is widely used in internal and external structural parts of home appliances. During the use of the air conditioner, the surface material is easily contaminated by oil, fingerprints, etc., which is difficult to remove, and under warm and humid conditions, microorganisms in the air are easy to attach and multiply on the surface. For the internal structure of the air conditioner, such as the air duct, dust and microorganisms in the air are easy to adhere, reproduce and deposit on the surface of the air...
