Embodiment 1

[0011] In terms of parts by mass: 80% silica sol and 20% ammonium aluminum carbonate; wherein the solid content of the silica sol is 40%, and the particle size of the ammonium aluminum carbonate is less than 1 μm≥90%.

[0012] (1) Slowly add 20 g of ammonium aluminum carbonate to 80 g of silica sol at a temperature of 30°C, and stir evenly at a speed of 200 r / min to obtain a mixed solution;

[0013] (2) Transfer the above-mentioned mixed liquid to a high-efficiency air-flow vibration mill and disperse for 30 minutes to obtain the wood modified slurry with flame retardant effect.

Embodiment 2

[0015] In terms of parts by mass: silica sol 90%, aluminum ammonium carbonate 10%; wherein the solid content of the silica sol is 5%, and the particle size of the ammonium aluminum carbonate is less than 1 μm≥90%.

[0016] (1) Slowly add 10g of aluminum ammonium carbonate to 90g of silica sol at a temperature of 60°C, stir evenly at a speed of 300r / min to obtain a mixed solution;

[0017] (2) Transfer the above-mentioned mixed liquid to a high-efficiency air-flow vibration mill and disperse for 60 minutes to obtain the wood modified slurry with flame retardant effect.

Abstract

The invention discloses wood modification pulp with a flame-retardant effect. The pulp is prepared from the following raw materials in parts by weight: 80-90% of silica sol and 10-20% of ammonium aluminum carbonate hydroxide. According to the invention, the silica sol and the ammonium aluminum carbonate hydroxide are compounded for use for the first time so as to obtain special flame-retardant pulp for wood modification, and the pulp is low in viscosity and good in dispersion stability, and has good fillibility to wood. After the pulp is filled in internal pores of wood, a highly efficient flame-retardant modified wood is formed, so that in the event of a fire, the two kinds of flame retardants collaboratively work, thereby effectively restraining the further occurrence of disasters. The flame-retardant pulp is an inorganic substance, and insoluble in water, therefore, the pulp is green, environment-friendly, and good in leaching resistance.

Description

Technical field [0001] The invention relates to a modified wood slurry with flame retardant effect. The slurry uses silica sol and ammonium aluminum carbonate in a compound manner, thereby achieving a double-effect flame retardant effect. Background technique [0002] As one of the traditional building materials, wood materials are widely used in the construction industry. Wood has natural texture and beauty, and is non-toxic and harmless. It is usually processed and processed into wood furniture, wood floors and other home decoration components. At the same time, wood The material is light and has a high specific strength. It is also widely used as a raw material for building wooden structures, wooden bridges, formwork, electric poles, sleepers, doors and windows. Compared with other building materials, wood is flammable and the fire is easy to spread. Therefore, the flame retardant treatment of wood and wood products is imperative. [0003] Although the flame-retardant treat...
