Preparation method for temperature-resistant reinforced wood-plastic composite material

[0039] A method for preparing a temperature-resistant reinforced wood-plastic composite material, comprising the steps of:

[0040] (1) Preparation of reinforced basalt fiber:

[0041] 1) First put the mullite powder into the nitric acid solution for soaking for 3 minutes, then filter it out and put it into the tartaric acid solution for soaking treatment for 4 minutes. Finally, filter out and rinse with deionized water for later use;

[0042] 2) Put the mullite powder treated in operation 1) into the calcination furnace, first heat and keep the temperature in the calcination furnace at 360°C, heat preservation and calcination for 25 minutes, then raise the temperature in the calcination furnace to 880°C, heat preservation and calcination Take it out after 45 minutes of processing, and let it cool naturally to room temperature for later use;

[0043] 3) Put the mullite powder treated in operation 2) into the modified treatment solution, heat to keep the temperature of the mo...

[0066] A method for preparing a temperature-resistant reinforced wood-plastic composite material, comprising the steps of:

[0067] (1) Preparation of reinforced basalt fiber:

[0068] 1) Put the mullite powder into the nitric acid solution for soaking treatment for 3.5 minutes. After the treatment is completed, filter it out and put it into the tartaric acid solution for soaking treatment for 4.5 minutes. After the treatment is completed, filter it out and put it into the sodium hydroxide solution for soaking treatment for 4 minutes. After the treatment is completed, filter out and rinse with deionized water for later use;

[0069] 2) Put the mullite powder treated in operation 1) into the calcination furnace, first heat and keep the temperature in the calcination furnace at 380°C, heat-preserve and calcine for 30 minutes, then raise the temperature in the calcine to 900°C, heat-preserve and calcine Take it out after processing for 50 minutes, and let it cool naturally to ro...

[0093] A method for preparing a temperature-resistant reinforced wood-plastic composite material, comprising the steps of:

[0094] (1) Preparation of reinforced basalt fiber:

[0095] 1) Put the mullite powder into the nitric acid solution for soaking treatment for 4 minutes. After the treatment is completed, filter it out and put it into the tartaric acid solution for soaking treatment for 5 minutes. After the treatment is completed, filter it out and put it into the sodium hydroxide solution for soaking treatment for 5 minutes. The treatment is completed Finally, filter out and rinse with deionized water for later use;

[0096] 2) Put the mullite powder treated in operation 1) into the calcination furnace, first heat and keep the temperature in the calcination furnace at 420°C, heat-preserve and calcine for 35 minutes, then raise the temperature in the calcine to 950°C, heat-preserve and calcine Take it out after 55 minutes of processing, and let it cool naturally to room ...
