Abstract

The invention relates to an antibacterial spraying-free material capable of efficiently releasing negative ions and a preparation method thereof, and the antibacterial spraying-free material capable of efficiently releasing negative ions comprises the following components in parts by weight: 60-90 parts of matrix resin, 2-10 parts of pearlescent pigment, 1-10 parts of negative ion releasing agent,0-5 parts of antibacterial agent, 1-5 parts of dispersing agent, 1-5 parts of compatilizer, 0.5-2 parts of coupling agent and 0.01-1 part of antioxidant. The preparation method of the negative ion releasing agent comprises the following steps: adding distilled water and tourmaline powder into a three-mouth cup, stirring in a cold water bath, and dropwise adding a titanium tetrachloride stock solution into the mixed solution; mixing an ammonium sulfate solution and hydrochloric acid, dropwise adding into the reaction system, mixing, stirring, heating and keeping the temperature; and regulatingthe pH value of the mixed solution, reacting for 1-5 hours, carrying out suction filtration and drying on the reaction solution, drying, calcining and cooling to obtain the material. The invention further provides a preparation method of the antibacterial spraying-free material capable of efficiently releasing the negative ions. The material can be widely applied to the technical field of polymermaterials.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a high-efficiency negative ion antibacterial spray-free material and a preparation method thereof. Background technique [0002] Low-carbon environmental protection, energy saving and emission reduction are one of the important issues in the development of the world today. In order to obtain a colorful appearance for home appliances, automobiles, medical equipment and other appearance parts, the surface of the plastic substrate is usually painted to achieve a bright, beautiful, Special appearance effect, but the spraying process has disadvantages such as complicated process, high cost, environmental pollution, health hazard, low yield rate, and difficulty in recycling. The spray-free technology came into being. The spray-free technology is to add special effect pigments, such as aluminum powder, copper powder, pearl powder, etc., to the resin base material, and modify i...
