Abstract

The invention discloses a raw bamboo protective agent. The raw bamboo protective agent consists of the following raw materials in parts by weight: 10-15 parts of dialkyl dimethyl ammonium chloride, 5-8 parts of chlorothalonil, 2-5 parts of triethanolamine, 6-10 parts of n-butyl alcohol, 1-3 parts of permethrin, 2-4 parts of sodium pentachlorophenate, 2-5 parts of N-2-styrene acrylic imidazole methyl carbamate, and 1-2 parts of lignosulfonic acid. A preparation method of the raw bamboo protective agent comprises the following steps: at 60-90 DEG C, dialkyl dimethyl ammonium chloride, permethrin, N-2-styrene acrylic imidazole methyl carbamate and n-butyl alcohol are mixed in parts by weight for stirring by 30-45 min; the obtained liquid is poured in a rotating evaporator for evaporating by 3-5 min; the liquid in the evaporator is retained, and is poured in a flask with sodium pentachlorophenate and triethanolamine mixed solution for heating and stirring in a boiling state; 30-60 min later, the heating is stopped; and finally, chlorothalonil and lignosulfonic acid are added in the flask for dissolving by afterheat of the flask, and are cooled to obtain the product. The raw bamboo protective agent is convenient for use and excellent in protecting effect.

Description

technical field [0001] The invention relates to the technical field of wood protection, in particular to a protective agent for raw bamboo. Background technique [0002] Raw bamboo refers to bamboo poles that have not been processed after felling. It effectively maintains the organizational structure and morphological characteristics of fresh bamboo, as well as the mechanical strength of fresh bamboo and the aesthetic effect of bamboo poles. Therefore, raw bamboo is widely used in furniture and building materials. field. [0003] However, raw bamboo contains more organic nutrients, among which protein is 1.5-6%, soluble sugar is about 2%, starch is 2.2-5.18%, fat and wax are 2.18-3.55%. The amount of water is as high as 30-40%. These substances are easy to cause insects, decay, mildew and cracking of bamboo, which seriously affects and limits the application and performance of raw bamboo. In order to make the original bamboo be effectively utilized and have a long service...
