[0004] With the development of the plastics industry, wood-plastic composite materials manufactured using polyolefin resins and wood fibers have been widely applied. Chinese Patent CN103342786B discloses a method for manufacturing a bagasse / polyethylene composite material, in which bagasse in the bagasse / polyethylene composite material is connected to polyethylene through chemical bonds, giving high tensile strength and impact strength, but there is still room for improvement in antiviral performance and antibacterial performance. Chinese Patent CN107987548B discloses a high-strength wood-plastic composite material which has very good tensile strength and flexural strength, but also leaves room for improvement in antiviral performance and antibacterial performance. SUMMARY OF THE INVENTION

[0005] In response to the shortcomings of the prior art, the present invention provides furniture, household decorative panels, and methods for manufacturing the same that are antibacterial and antiviral and emit negative oxygen ions, in order to solve problems such as the lack of room for improvement in the antiviral and antibacterial properties of conventional household wood-plastic composite materials.

[0006] To achieve the above objectives, the technical solutions employed by the present invention are as follows.

[0007] A method for manufacturing household decorative paneling that has antibacterial and antiviral properties and releases negative oxygen ions is: Step 1 involves weighing the dried raw materials, namely polyolefin resin, wood fibers, nanosilicon sheets, lubricants, antioxidants, flame retardants, coupling agents, and inorganic reinforcing fillers. Step 2 involves stirring and mixing wood fibers, nanosilicon sheets, lubricants, antioxidants, flame retardants, coupling agents, and inorganic reinforcing fillers to obtain a mixed material. Step 3 involves adding polyolefin resin to the mixed material, mixing uniformly, melt-kneading, extruding and granulating to obtain composite particles, The method includes step 4, in which composite particles are extruded in a molten state using an extruder and calendered to obtain a household decorative panel material that is antibacterial and antiviral and releases negative oxygen ions.

[0008] Preferably, in step 1, the dried raw materials contain, by weight, 20-30 parts polyolefin resin, 35-50 parts wood fiber, 5-10 parts nanosilicon sheet, 3-5 parts lubricant, 0.5-1 part antioxidant, 1-3 parts flame retardant, 0.5-1.5 parts coupling agent, and 3-5 parts inorganic reinforcing filler.

[0009] Preferably, the polyolefin resin contains polyethylene.

[0010] Preferably, the polyethylene includes high-density polyethylene.

[0011] Preferably, the lubricant comprises a stearate, the antioxidant comprises pentaerythritol tetrakis[3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate], the flame retardant comprises 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide, the coupling agent comprises a silane coupling agent, and the inorganic reinforcing filler comprises glass fibers.

[0015] This furniture is made from household decorative paneling material that has antibacterial and antiviral properties and emits negative oxygen ions.

[0016] Compared to the conventional technology, the beneficial effects of the present invention are as follows:

[0017] In this invention, a household decorative panel material is synthesized using polyolefin resin and wood fibers as the main raw materials, and a variety of properties are achieved in the household decorative panel material by adding nanosilicon sheets, lubricants, antioxidants, flame retardants, coupling agents, and inorganic reinforcing fillers.

[0018] Nano-silicone sheets are obtained from natural inorganic bentonite or attapulgite, and their layers are peeled off into sheets using peeling technology. They contain a large amount of negative charge, and the negative charge exposed to the outside forms a strong adsorption force, adsorbing positively charged bacteria, viruses, or odors onto their surface. By utilizing the mechanism of adsorption and adhesion prevention of harmful molecules by natural silicone sheets, special effects such as environmental purification, antibacterial and antifungal properties, dust removal and deodorization, and UV protection can be achieved, and the proliferation of pathogenic bacteria can be effectively prevented, thereby purifying environmental quality. The addition of nano-silicone sheets can effectively improve the antiviral and antibacterial properties of household decorative paneling materials, and can also release a large amount of negative oxygen ions.

[0019] By adding flame retardants, the flame retardant properties of household decorative paneling can be effectively improved; by adding inorganic reinforcing fillers, the mechanical properties of household decorative paneling can be effectively improved; and by adding coupling agents, the compatibility and dispersion uniformity between each component can be effectively improved.

[0032] Test example Performance tests are performed on the household decorative paneling materials manufactured in the above examples and comparative examples.

[0033] (1) Antiviral performance: The antiviral activity of the household decorative paneling materials manufactured in Examples 1 to 6 and Comparative Examples 1 to 4 was measured in reference to the standard ISO 21702-2019, and the test results are shown in Table 1. [Table 1]

[0034] (2) Antimicrobial performance: Referring to standard QB / T4371-2012 "Evaluation of antimicrobial performance of furniture Appendix B: Film application method", the bacteriostatic rate of household decorative board materials manufactured in Examples 1 to 6 and Comparative Examples 1 to 4 was measured, with an action time of 24 hours, and the test results are shown in Table 2. [Table 2]

[0035] (3) Negative oxygen ion emission performance: Referring to standard JC / T2110-2012 "Method for measuring indoor air ion concentration", the air negative ion concentration of the household decorative board materials manufactured in Examples 1 to 6 and Comparative Examples 1 to 4 was measured, and the test results are shown in Table 3. [Table 3]

[0036] As can be seen from Tables 1, 2, and 3, the household decorative panel material manufactured in the present invention has good antiviral and antibacterial properties and can release a large amount of negative oxygen ions. The nanosilicon sheet is obtained from natural inorganic bentonite or attapulgite, and its layer is peeled off into a sheet form by peeling technology. It contains a large amount of negative charge, and the negative charge exposed to the outside forms a strong adsorption force, adsorbing positively charged bacteria, viruses or odors onto its surface. By utilizing the mechanism of adsorption and adhesion prevention of harmful molecules by the natural silicone sheet, special effects such as environmental purification, antibacterial and antifungal properties, dust removal and deodorization, and UV protection can be achieved, and the proliferation of pathogenic bacteria can be effectively prevented, thereby purifying environmental quality. Compared to Example 1, in Comparative Example 1, where the nanosilicon sheet was not added, the antiviral performance, antibacterial performance, and ability to release negative oxygen ions were all significantly reduced. In Comparative Example 2, the flame retardant 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide was not added, and there was no effect on the antiviral performance, antibacterial performance, and ability to release negative oxygen ions. In Comparative Example 3, the inorganic reinforcing filler glass fiber was not added, and there was no effect on the antiviral performance, antibacterial performance, and ability to release negative oxygen ions. In Comparative Example 4, the coupling agent γ-(methacryloyloxy)propyltrimethoxysilane was not added, and the dispersibility of the nanosilicon sheet decreased, resulting in a slight decrease in antiviral performance, antibacterial performance, and ability to release negative oxygen ions.

[0037] (4) Flame retardancy: Referring to standard GB / T2406.1-2008 "Plastics - Measurement of combustion behavior by oxygen index method Part 1: Guidelines", the limiting oxygen index of the household decorative paneling manufactured in Examples 1 to 6 and Comparative Examples 1 to 4 was measured, and the test results are shown in Table 4. [Table 4]

[0038] As can be seen from Table 4, the household decorative panel material manufactured in the present invention has good flame retardancy. The flame retardancy of the household decorative panel material can be effectively improved by adding a flame retardant. Compared to Example 1, in Comparative Example 1, no nanosilicon sheet was added, which mainly affected the antiviral performance, antibacterial performance and the ability to release negative oxygen ions, but had no clear effect on the flame retardancy. In Comparative Example 2, no flame retardant, 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide, was added, and the flame retardancy was clearly reduced. In Comparative Example 3, no inorganic reinforcing filler, glass fiber, was added, and there was no clear effect on the flame retardancy. In Comparative Example 4, no coupling agent, γ-(methacryloyloxy)propyltrimethoxysilane, was added, and there was no clear effect on the flame retardancy.

[0039] (5) Mechanical performance: Referring to standard GB / T1040.1-2006 "Measurement of tensile performance of plastics, Part 1: General provisions", the tensile strength of the household decorative boards manufactured in Examples 1 to 6 and Comparative Examples 1 to 4 was measured, and the test results are shown in Table 5. [Table 5]

[0040] As can be seen from Table 5, the household decorative paneling material manufactured in the present invention has good mechanical properties. The mechanical properties of the household decorative paneling material can be effectively improved by adding an inorganic reinforcing filler. Compared to Example 1, in Comparative Example 1, no nanosilicon sheet was added, and since the nanosilicon sheet can help improve the mechanical properties of the paneling material as an inorganic material, the tensile strength was slightly reduced. In Comparative Example 2, the flame retardant 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide was not added, and there was no clear effect on the mechanical properties. In Comparative Example 3, the inorganic reinforcing filler, glass fiber, was not added, and the mechanical properties were clearly reduced. In Comparative Example 4, the coupling agent γ-(methacryloyloxy)propyltrimethoxysilane was not added, and the dispersibility of the inorganic reinforcing filler decreased, resulting in a slight decrease in mechanical properties.
