Abstract

This invention is with regard to a kind of long-acting disinfectant. Its ingredients are composed of 2,4,4'-trichloro-2'-hydroxy diphenyl ether, amino emulsified-silica resin, 1,2 propanediol, fatty alcohol polyethenoxy ether and distilled water. First, the fatty alcohol polyethenoxy ether should be mixed with distilled water, 2,4,4'-trichloro-2'-hydroxy diphenyl ether is to be put into a high speed agitator, to make the mixture in the agitator dissolved by stirring at the temperature of 50 to70 DEG C. When the temperature has been lowed down, the amino-silica-milk resin should be added. After stirring in the agitator at low revolution speed for several minutes, provided the mixture is homogeneous, the end product can be obtained. The long-acting disinfectant has the specific properties of excellent disinfecting effect, long-acting potency, repeated-pollution resistant, non-toxic and safe etc. Its antiseptic rate at surface and bacteriostasis after two years storage, could still be up to 66%.

Description of the invention (2) The purpose of the present invention is to propose a long-acting disinfectant with high stability, long-term effect, good bactericidal effect, wide sterilization range, high utility, safety and non-toxicity, in order to facilitate The need for long-term disinfection and antibacterial sanitary treatment of banknotes or paper products' does not affect the appearance and physical and chemical properties of the surface of the banknotes or paper products. Another object of the present invention is to provide a method for preparing the above-mentioned long-acting disinfectant. [Detailed description of the invention] The raw materials of the long-acting disinfectant of the present invention include 2, 4, 4'-trichloro-2'_hydroxydiphenyl ether, amino silicone resin, 1,2 propylene glycol, fatty alcohol polyoxyethylene ether And distilled water, wherein the weight ratio of each component is: 2,4,4'_trichloro-2'-hydroxydiphenyl ether 20-50 parts aminosilicone resin 3 -10 parts 1,2 propylene glycol 20 to 30 parts of fatty alcohol polyoxyethylene ether 10 to 30 parts of distilled water 10 to 40 parts of which, the trade name of the amino silicone emulsion resin is TSA2 02 silicone emulsion resin, and the distilled water may be sterile distilled water.

Turn to stir for 2-6 minutes. It includes the above-mentioned additive group 5, the invention description (3), and the 40 bacteria obtained by distilling the water on the surface of the thin paper product. The long and stupid material of the present invention, 1, 2 propylene glycol-reinforced -2, 4, has a bactericidal effect. Non-toxic properties greatly improve the use of contaminated bacteria can be solved. Bacteria and gonorrhea are dual-use 'naturally protect its application method. Banknotes or their banknotes or other uses'. In particular, the following combination of Example 1 = / ° fortification-hydroxyl / amino dibenzyl Ether silicone emulsion disinfectant can be used to obtain banknotes or other long-lasting disinfection treatment agents when it is released to a 0. 5-1. 3wt% aqueous solution. = Back-breaker is characterized by the addition of the long-acting agent amino ^^ emulsion resin and synergist at 2, 4, 4, _trichloro-2, -hydroxyl as a long-acting agent and Synergistic agent to prepare 5 4 dichloro-2-ammonia / hydroxydiphenyl ether silicon emulsion disinfectant, good fruit, and long-lasting effect, good resistance to repeated pollution, safe, good, make sterilization of HD 2 4 4 Both long-term performance and long-term performance are obtained. The problem of frequent problems on the surface of banknotes or other paper products will also pass the application of the long-acting disinfectant of the present invention. For E. coli, Staphylococcus aureus, and white strains. , 36 kinds of common bacteria, such as bacteria, tubercle bacilli, all have; after killing for years, the surface antibacterial rate is still reached. ^ ί t 5 — 丨 · 3Wt% aqueous disinfectant solution can be sprayed or dipped directly: π mouth surface, after regular temperature or heating and drying, the surface of paper products can achieve long-term antibacterial effect for one to three years. Solve the problem of bacterial contamination of frequently used banknotes. The examples further describe the invention. A long-acting consumer, its raw materials include 2,4,4, ~ trichloro-2, -hydroxydibenzene =, amino silicone resin, 1,2 propylene glycol, fatty alcohol polyoxyethylene ether and distilled water Wherein, the weight ratio of each component is 40 parts of 2,4,4'-trichloro_2'-hydroxydibenzyl ether.
