Method for preparing composite wood with hydroxide

Abstract

The invention discloses a method for preparing composite wood with hydroxide. The method comprises the steps that an inflaming retarding solution is prepared, and after solid materials and liquid materials of components are mixed and stirred evenly, solids and liquid are mixed at normal temperature to obtain the inflaming retarding solution; and the mixed inflaming retarding solution is impregnated in wood, constant temperature treatment is carried out in a hydrothermal reaction kettle, and finally cooling and washing are carried out. According to the method, inflaming retarding liquid has the beneficial effects of being good in stability, non-volatile, free of generation of poisonous gas, free of halogen, environment-friendly, good in inflaming retarding effect, efficient, low in use level, low in cost and the like, and the prepared wood has the effects of retarding inflaming, restraining smoke, resisting corrosion and damage by worms and the like. The preparation method is simple in structure, and industrial production is achieved easily.

Description

technical field [0001] The invention belongs to the technical field of wood production, in particular to a preparation method of hydroxide-containing composite wood. Background technique [0002] Wood is an important material for industrial engineering. In Japan, Europe and other countries and regions, more and more wood is used for fencing and interior decoration. In recent years, with the gradual improvement of people's living standards, the proportion of total wood consumption for building decoration has been increasing year by year. However, untreated wood and its products are flammable materials and present fire hazards. According to the analysis of fire statistics from various countries in the world, 21% of fires are related to wood. In order to reduce fires, many countries have legally required that the wood used must be flame-retardant treated; in my country, the Ministry of Public Security has also introduced a series of mandatory fire regulations. and application...

Problems solved by technology

Wood flame retardants are often treated with flame retardants, but among the existing wood flame retardants, organic flame retardants are not recommended because they emit a large amount of toxic gases when burned and are expensive; The performance is not ideal and there are problems such as difficulty in impregnation and darkening of the treated material. It has not been widely used. At present, the most widely used inorganic flame retardant has the advantages of wide sources, low price, non-toxic and environmental protection. However, many inorganic flame retardants are currently The flame retardant effect of the flame retardant on wood is not obvious, and the anti-loss performance is poor, and the deformation is large
