Problems solved by technology

Wood has a wide range of functions, mainly used in construction and daily necessities. When manufacturing these products, wood needs to be processed accordingly. The processed wood cannot be accurately identified, and merchants may mislead consumers, so that consumer rights cannot be guaranteed. , so it is necessary to identify the slice softening of wood
[0003] Traditional wood softening is mainly cooking in boiling water, which takes several weeks to soften, high energy consumption, and low softening efficiency. In order to improve softening efficiency and reduce softening costs, wood softeners are mainly used to accelerate softening, but the current wood softeners are mainly softening. The aqueous solution of the agent usually needs to be softened at high temperature for half a day to one day, and the softening efficiency needs to be improved

Abstract

The invention discloses a wood softener, and a preparation method and application thereof. The wood softener is composed of the following materials, by weight: 14-18 parts of hydrogen peroxide, 5-7 parts of oleoyl cholamine, 4-6 parts of potassium trifluoromethane sulfonate, 2-4 parts of N,N-Dimethylacetamide, 1-5 parts of lithium acetate, and 0.8-1.2 parts of sodium tripolyphosphate, The wood sofener is prepared from hydrogen peroxide, oleoyl ethanolamine, trifluoromethane sulfonic acid potassium, N,N-Dimethyl acetamide, and lithium acetate and sodium tripolyphosphate according to the process; the prepared wood softener has low softening temperature and short softening time; under the same softening temperature, the softening time can be shortened by about 50%; softening efficiency is high, the cost of the wood softening can be reduced, and the softening effect is good; and the preparation method is simple, can easily achieve industrial production and is worth popularizing.

Description

technical field [0001] The invention relates to a chemical auxiliary agent, in particular to a wood softener and its preparation method and application. Background technique [0002] Chemical additives are chemical additives used in a certain industry. There are many types, generally including metal processing additives, plastic additives, papermaking additives, construction additives, water treatment additives, coating additives, leather additives , Auxiliaries for the electronics industry, textile printing and dyeing auxiliaries, wood auxiliaries, etc. Wood has a wide range of functions, mainly used in construction and daily necessities. When manufacturing these products, wood needs to be processed accordingly. The processed wood cannot be accurately identified, and merchants may mislead consumers, so that consumer rights cannot be guaranteed. , so it is necessary to identify the slice softening of wood.
