Low-expansion co-extrusion wood-plastic floor and preparation method thereof
The invention discloses a low-expansion co-extrusion wood-plastic floor and a preparation method thereof. The low-expansion co-extrusion wood-plastic floor comprises a core body and an outer layer arranged on the surface of the core body, the core body comprises the following components in parts by weight: 40-50 parts of a polyethylene mixture, 55-70 parts of special wood flour, 3-5 parts of a lubricant and 12-18 parts of filler; the outer layer is prepared from the following components in parts by weight: 40 to 50 parts of high-density polyethylene, 25 to 35 parts of glass fiber, 2 to 5 parts of infrared reflection pigment, 0.6 to 0.8 part of anti-ultraviolet agent, 1 to 2 parts of stabilizer and 0.5 to 1.5 parts of coupling agent. At present, for wood-plastic floors, the particle size of wood flour used in the wood-plastic floors is 60-80 meshes, namely the particle size range is 198-245 microns, the thermal expansion performance of the wood-plastic floors can be effectively improved by adopting the wood flour with the particle size of 800-850 microns as the raw material of the core body, and therefore the situation that when the wood-plastic floors are used outdoors, the service life is shortened due to the fact that a large amount of sunlight energy is absorbed can be avoided, and the service life of the wood-plastic floors is prolonged. And the service life is prolonged.
本发明公开了一种低膨胀共挤木塑地板及其制备方法，包括芯体和设置在所述芯体表面的外层；所述芯体按重量份包括如下组分：聚乙烯混合物40‑50份、特殊木粉55‑70份、润滑剂3‑5份和填料12‑18份；所述外层按重量份包括如下组分：高密度聚乙烯40‑50份、玻璃纤维25‑35份、红外反射颜料2‑5份、抗紫外线剂0.6‑0.8份、稳定剂1‑2份和偶联剂0.5‑1.5份。目前对于木塑地板，使用的木粉粒径为60‑80目，即粒径范围为198‑245um，本发明通过采用粒径为800‑850um的木粉作为芯体的原料，能够有效提高木塑地板的热膨胀性能，从而能够避免在户外使用时，因吸收大量太阳光能量导致使用寿命缩短的情况，延长了使用寿命。
