Chinese fir floor material

Abstract

The invention discloses a Chinese fir floor material, comprising: a plasticizer, a fiber material that includes more than one inorganic fiber or more than one organic fiber, and thermoplastic resin. The fiber material is oriented. The plasticizer and the fiber material are polarized. The Chinese fir floor material herein is air-dried under rain-shedding and ventilated environment, moisture in theChinese fir floor material can be volatilized from its both sides, chances for the material to crack and deformation degree of the material under drying are decreased, and comprehensive utilization rate of the material is increased; the Chinese fir floor material is made by splicing and gluing a plurality of main square strips and a plurality of splice square strips in alternate manner, the alternate arrangement of wood fiber during glue-splicing enables residual stress in the square strips of Chinese fir to be homogenized, chances for the Chinese fir floor material to warp and crack are decreased, and the quality of the Chinese fir floor material is improved.

Description

technical field [0001] The invention relates to a Chinese fir floor material. Background technique [0002] Flooring materials using petroleum-based resins such as polyvinyl chloride (PVC) are widely used mainly in buildings such as houses, mansions, apartments, office buildings, and shops. [0003] The above-mentioned floor materials are produced by extrusion or calendering using resins such as polyvinyl chloride (PVC). However, since the raw materials are all obtained from crude oil, etc., which are limited resources, problems such as difficulties in the supply and demand of raw materials are expected to occur in the future due to the depletion of petroleum resources. [0004] In addition, considering the recent environmental problems that have attracted attention, polyvinyl chloride (PVC)-based flooring materials are likely to emit harmful substances, and there is a problem that they also impose a burden on the environment when they are discarded. [0005] According to ...

AI Technical Summary

Problems solved by technology

However, since all raw materials are obtained from crude oil, which is a limited resource, etc., it is expected that problems such as supply and demand of raw materials will occur in the future due to the depletion of petroleum resources.

[0004] In addition, considering the recent environmental problems that have attracted much attention, there are problems that polyvinyl chloride (PVC) floor materials are prone to discharge harmful substances, and they also impose a burden on the environment when they are discarded.

[0005] According to this, there is disclosed a method of forming flooring materials using sustainable resources such as biodegradable resins such as polylactic acid. However, biodegradable resins have low thermal shock resistance and low strength, and it is difficult to apply calendering processes. thereby reducing production efficiency

Furthermore, in the case of using a biodegradable resin or the like to form a floor material, the dimensional stability is reduced due to expansion or contraction caused by environmental factors such as external temperature.

That is, in the case of floor materials made of biodegradable resins, dimensional changes occur due to differences in temperature and humidity, thereby frequently causing the joints of the floor materials to be pulled apart due to shrinkage, or the surface of the floor materials to be stretched due to expansion. On the other hand, there is a problem that it is difficult to use it continuously and stably due to the phenomenon that it is swollen like a wave.
