Example Embodiment

[0038] According to another aspect of the present invention, there is also provided a method for preparing the above-mentioned composite profile, comprising the following steps: forming a resin surface layer 10 from a first raw material comprising ABS resin by a first molding process; A resin inner layer 20 is formed on one side of 10 , the second raw material for forming the resin inner layer 20 includes at least one thermoplastic resin other than ABS resin, and the first raw material and / or the second raw material also includes an antibacterial agent.

[0039] In the above-mentioned preparation method, a forming process such as vacuum forming and extrusion forming can be directly used to form the laminated resin surface layer 10 and the resin inner layer 20 at the same time, or the above-mentioned first raw material for forming the resin surface layer 10 can be preformed first, A preform is obtained, and then the above-mentioned second raw material containing other resins is ...

Example Embodiment

[0042] Example 1

[0043] The preparation method of the composite profile provided by this embodiment includes:

[0044] Provide a first raw material comprising ABS resin and an antibacterial agent, and provide a second raw material comprising fiber-reinforced polyethylene, wherein the antibacterial agent is powdered calcium phosphate supported alkyl dimethyl ammonium ions, wherein the number of carbon atoms of the alkyl group is is 8, and the particle size is 0.04 μm.

[0045] The first raw material and the second raw material are laminated and molded, the first raw material forms a resin surface layer, the second raw material forms a resin inner layer, and the resin surface layer and the resin inner layer are laminated to form a composite profile.

[0046] The mass concentration of the antibacterial agent in the resin surface layer is 5%, and the thicknesses of the resin surface layer and the resin inner layer are both 0.4 mm.

Example Embodiment

[0047] Example 2

[0048] The difference between the preparation method of the composite profile provided in this example and Example 1 is:

[0049] Both the first raw material and the second raw material include an antibacterial agent, and the antibacterial agent is a powdered titanium phosphate supported dialkyldimethylammonium ion, wherein the number of carbon atoms of the alkyl group is 18, the particle size is 20 μm, and the antibacterial agent in the resin surface layer is The mass concentration of the agent is 0.1%, and the mass concentration of the antibacterial agent in the resin inner layer is 0.1%.

Abstract

The invention provides a composite profile and a preparation method thereof. The composite profile comprises a resin surface layer and a resin inner layer which are overlapped, wherein materials for forming the resin surface layer comprise ABS resin, materials for forming the resin inner layer comprise at least one thermoplastic resin other than ABS resin, and an antibacterial agent is contained in the resin surface layer and/or the resin inner layer. Through the composite profile, bacterial reproduction on the surface can be inhibited, good cleanliness and a good appearance of products can bemaintained, and meanwhile, the resin inner layer is formed by using the thermoplastic resin different from the ABS resin so as to enhance the resin inner layer according to application requirements,so that the antibacterial ABS resin composite material with good wear resistance and high strength is provided.

Description

technical field [0001] The invention relates to the field of composite material products, in particular to a composite profile and a preparation method thereof. Background technique [0002] ABS resin is a terpolymer of acrylonitrile, butadiene and styrene, which has excellent impact resistance, heat resistance, low temperature resistance, chemical resistance and electrical properties, and has the advantages of easy processing and stable product size. , Widely used in household appliances, building materials, electronic appliances and automobiles and other fields. As plastic products are closely related to people's life and industrial production, and people are often plagued by microorganisms such as bacteria and viruses in modern life, countries around the world have invested a lot of scientific research and development of various antibacterial plastics. At present, ABS resin is widely used in household appliances, daily necessities, sanitary ware, refrigerator panels and ...
