Embodiment Construction
[0020] A method for preparing a rubber floor with antibacterial and antibacterial effects, using low-temperature plasma technology to modify the surface of the EPDM layer, and then coating a layer of antibacterial film to prepare the rubber floor. The antibacterial film is made of natural Composed of latex and chitosan.
[0021] The specific process steps are as follows:
[0022] (1) Mixing: 90 parts of EPDM rubber and EPDM rubber, 2 parts of stearic acid, 23 parts of precipitated silica, 2 parts of anti-aging agent, 3 parts of sulfur, 3 parts of silane coupling agent, 6 parts of foaming agent, 0.8 parts of antioxidant, and 6 parts of flame retardant are mixed and put into the internal mixer for banburying. The banburying temperature is 140 ° C, the banburying time is 20 minutes, and then mixed on the open mixer for 20 minutes. The refining temperature is 80°C;
[0023] (2) Calendering: Carry out calendering on a three-roller calender for the above-mentioned rubber mixing af...

Abstract
The invention discloses a preparation method of a rubber floor with antibacterial and bacterium-inhibition effects. According to the method disclosed by the invention, surface modification is carried out on an ethylene-propylene-diene monomer layer by adopting a low-temperature plasma technology; then the ethylene-propylene-diene monomer layer is coated with one layer of antibacterial rubber film to prepare the rubber floor; the antibacterial rubber film is prepared from natural latex and chitosan. Polar groups including hydroxyl and the like are introduced into the surface through low-temperature plasma treatment, and the antibacterial rubber film is cross-linked on the surface of a rubber layer by utilizing active hydrogen, so that the rubber floor has excellent antibacterial and bacterium-inhibition properties; meanwhile, a polyisoprene molecular chain in the natural latex and a chitosan molecular chain are mutually entangled to form a cross-linked network, so that the tensile strength and the elastic modulus of the rubber film are improved and a product has excellent physical performance.
Description
technical field [0001] The invention relates to the field of rubber products, in particular to a method for preparing a rubber floor with antibacterial and antibacterial effects. Background technique [0002] Rubber products have special high elasticity, excellent properties such as wear resistance, shock absorption, insulation and sealing, and are more and more popular among people, and their application fields are becoming wider and wider. Due to the above advantages, rubber flooring has gradually entered the ranks of indoor and outdoor floor decoration. It is suitable for laying floors in hotels, hotels, gymnasiums, conference halls, gyms, dance rooms, toilets, etc. It has anti-slip, fitness, aesthetics and protection functions. [0003] Due to the long-term use and impregnation of various pollutants such as tea stains and sweat stains, the rubber floor currently used is prone to breed bacteria on the surface and affect human health. Contents of the invention [0004] ...
