Embodiment

[0014] The composition of the wood flame retardant is: polypropylene 20%, polyethylene 30%, ethylene-vinyl acetate copolymer 20%, EPDM rubber 20%, aluminum hydroxide 2%, zinc borate 3%, decabromo Diphenylethane 5%.

[0015] First prepare the flame retardant and water to form a flame retardant solution, the ratio of flame retardant to water is 1:3.

[0016] The processing steps are as follows: a. Saw the wood that has passed the high-temperature heat treatment into certain specifications of boards according to production requirements; b. Palletize the boards and place them in a closed container, and then pump the pre-configured wood flame retardant into the airtight container. Inside the container; c. Then heat the airtight container to 50-60°C, keep the temperature and evacuate the airtight container. Yes, the pressure in the airtight container reaches 20-50 KPa, and stay at this pressure and temperature for 2-3 hours; d 1. Open the drain valve of the airtight container to di...

Abstract

The invention discloses a wood fire-retarding treatment method, comprising the following steps: a, sawing wood into plates of a certain specification according to production requirements; b, stacking the plates in a closed container, and pumping a wood fire retardant prepared in advance into the closed container; c, heating the closed container to 50-60 DEG C, vacuumizing the closed container at 50-60 DEG C till the pressure in the closed container is up to 20-50KPa, and keeping the pressure and the temperature for 2-3 hours; d, opening a drain valve of the closed container to discharge the flame retardant, cooling the wood to room temperature, then vacuumizing the closed container again till the pressure in the closed container is up to 20-50KPa, keeping the pressure for 10-15 minutes, opening the closed container, and taking out the wood; and e, standing the wood for 1-2 days before the wood is put into use. The wood treated by the method is low in rate of getting damp, is free of ammonia gas release, causes small corrosion to metal, is free of halogen harmful substances and is good in flame retardation.

Description

technical field [0001] The invention relates to a fire-retardant treatment method for wood, which belongs to the technical field of furniture production. Background technique [0002] The main material of Shanghai-style Western-style furniture is wood, and the fabric is cloth or leather. However, no matter whether it is wood, cloth or leather, it is inflammable. Once a fire breaks out, it is difficult to escape, which poses a great threat to the safety of users' lives and properties. For thousands of years, people have not found a good solution. Therefore, the flame retardant research of furniture is very important. Contents of the invention [0003] The purpose of the present invention is to provide a fire-retardant treatment method for wood. The wood treated by the method has low moisture regain, no ammonia gas release, low corrosion to metal, no halogen and harmless substances, and good fire-retardant performance of wood. [0004] The technical scheme adopted in the p...
