| titleOfInvention | Wood-plastic composite section and preparation method thereof |
| abstract | The invention discloses a wood-plastic composite section and a preparation method thereof. The wood-plastic composite section is characterized by comprising a shell and a light material filled in the shell, the shell is made of a wood-plastic composite, and the density of the light material is lower than that of the wood-plastic composite. A shell preparation method includes uniformly mixing raw materials prior to extrusion molding, and the raw materials include plastic, a wood fiber material and a flame retardant. A flame retardant preparation method includes subjecting phosphoric acid and pentaerythritol to first contact reaction for 0.5-5 hours at the temperature of 100-180 DEG C, adding polyether polyol, ammonium polyphosphate and melamine and/or urea into a product obtained by the first contact reaction, and performing second contact reaction for 0.5-4 hours at the temperature of 100-180 DEG C. The section has excellent flame retardance. In addition, the light material is filled in the shell, so that strength of the section is improved on the premise of not increasing the weight of the section greatly. |
