Problems solved by technology

The wood-plastic floor currently sold on the market usually uses plant fibers and thermoplastics to add related additives, and is melt-blended and extruded. There are problems such as poor interface compatibility between wood fibers and thermoplastics, low thermal conductivity, and poor dimensional stability. It is easy to warp and other problems, and can only be used as an ordinary home floor, and cannot meet the growing needs of geothermal flooring

Abstract

The invention discloses a straw-based wood plastic geothermal floor and a fluorine treatment based floor processing method. The floor comprises the following components by mass: 30-35% of a PVC and polyether block amide blend, 5-7% of nanoscale bamboo charcoal powder, 15-25% of porcelain stone powder, 4-6% of a lubricant, 1-3% of a compatilizer, and the balance a rice straw and rice husk mixture. The processing method consists of: firstly crushing the rice straw and rice husk mixture to 300 meshes, then performing fluorination modification, and mixing the modified mixture with porcelain stone powder, adding the PVC and polyether block amide blend, nanoscale bamboo charcoal powder, the lubricant, the compatilizer and other components, and carrying out extrusion by an extruder so as to obtain a finished product. The method provided by the invention utilizes the crop straw and the green body waste of ceramic machining enterprises to replace a lot of wood materials, and optimizes the formula, the obtained geothermal floor has the advantages of high heat conduction efficiency, low thermal expansion rate, and difficult buckling deformation, can be widely used in the geothermal floor field, and has good market prospects.

Description

technical field [0001] The invention relates to a wood-plastic composite material, in particular to a wood-plastic geothermal floor prepared by using straw and a floor processing method based on fluorine treatment. Background technique [0002] my country is a large traditional agricultural country, which produces about 800 million tons of various crop straws every year. The main application methods include returning straw to the field, turning straw into energy, processing feed, straw-based panels, etc., but more than half of the straw resources are not yet available. If they are used reasonably and effectively, they are often incinerated, causing great pollution to the air. [0003] With the rapid development of the ceramic industry, ceramic industry waste is increasing day by day. According to estimates, the production of wall and floor tiles in my country alone produces about 500,000 tons of green waste products every year. These porcelain stone wastes are usually simply ...
