Abstract

The invention discloses a waterproof and flame-retardant treatment method for wooden building materials, which comprises the following steps: soak the wooden building materials in warm water, take them out, pump at 1.2-1.6MPa for 1-2h, boost the pressure to 2-2.4MPa and continue pumping Inhale for 20-40min, soak in warm water again, take it out, suck at 3-3.6MPa for 2-4h, and get a treated wooden building material; self-crosslinking silicone emulsion, silane coupling agent, dodecylbenzenesulfonate Sodium acid, ammonia water, ammonium polyphosphate, and water were mixed, and stirred at 20-26°C for 10-20 minutes to obtain the first impregnating solution; the primary treated wooden building materials were immersed in the first impregnating solution, and then taken out to obtain secondary treated wooden building materials; Submerge the wooden building material for the secondary treatment in the second impregnation solution, take it out and carry out drying treatment for 10-20 hours at a drying temperature of 70-80°C, and then perform thermosetting compression treatment.

Description

technical field [0001] The invention relates to the technical field of building material treatment, in particular to a waterproof and flame-retardant treatment method for wooden building materials. Background technique [0002] With the development of the country's economic construction and the improvement of people's living standards, people's demand for wood is increasing. The implementation of natural forest protection projects has made the contradiction between supply and demand of timber more prominent. In order to alleviate the contradiction between supply and demand, my country has built a large area of ​​fast-growing tree plantations. Compared with natural forest trees, fast-growing tree species are limited by factors such as short growth years, resulting in great differences between early and late wood, loose material, brittle quality, and poor mechanical properties. Therefore, artificial fast-growing forest wood is difficult to be used for furniture manufacturing ...
