Embodiment 1

[0033] Take the following raw materials by weight

[0034]

[0035] The specific preparation is carried out according to the following steps:

[0036] High-speed mixing and dehumidification process:

[0037] The various materials in the above formula are put into a high-speed mixer with a rotating speed of 650-1300RPM and mixed, the mixing time is 10-20 minutes, the dehumidification temperature is 140°C, and the dehumidification time is 10 minutes;

[0038] Granulation mixing process:

[0039] A 75-type co-rotating parallel twin-screw granulator was used, the granulation temperature was controlled at 120-210 degrees Celsius, and the current was 140-150 amperes.

Abstract

The invention discloses a low-temperature type wood-plastic floor and a preparation technology thereof. The floor comprises substances of: plastic particles, plant fiber, a filling material, a compatibilizer, a lubricant, a pigment, and functional auxiliary agents. Compared with existing technologies, according to the invention, melted and modified plastic particles are adopted, the components are well formulated, and the mold of the product is improved. Under a temperature of -34 DEG C to 60 DEG C, the linear expansion coefficient of the prepared product is smaller than 5*10<-5>. When the product is processed through three times of freeze-thaw cycling tests according to ASTM D6109-10, the bending strength retention of the product is more than 97%.

Description

technical field [0001] The invention relates to a wood-plastic floor and a preparation process thereof, in particular to a low-temperature-resistant wood-plastic floor and a preparation process of the floor. technical background: [0002] As an outdoor paving material, wood-plastic flooring has become a new decorative trend because of its moth-proof, mildew-proof, weather-resistant, maintenance-free, and wood-like appearance. In garden landscape and other places, wood plastic floor is widely used. However, at present, in alpine areas and areas with large temperature differences between day and night or four seasons, the early-paved wood-plastic floor exposes problems such as product cracking, excessive cold and heat shrinkage, and product warping. At present, China has not developed special low-temperature-resistant wood-plastic floor products for such problems. For example, in the cold regions of northern Europe, Russia, Australia and other countries, the market prospect ...
