Abstract

The invention relates to the field of the production of a floor board, and particularly discloses a composite floor with small expansion rate and contraction rate and a production method thereof. The composite floor board comprises a wearable layer, a color film layer and a base material layer from top to bottom in sequence, wherein the base material layer consists of calcium carbonate, PVC (Polyvinyl Chloride), a plasticizer, a stabilizer and a modifier ACR (Acrylics); the production method comprises the steps of processing for shaping, implementing thermal compounding, implementing surface UV (Ultraviolet) and tempering, cooling and finally implementing slicing and grooving. According to the composite floor board and the production method thereof, the calcium carbonate adopted for the composite floor board has a specification of over 500 meshes; the processing temperature is rationally controlled through the production method, so that the contraction rate and the expansion rate can be effectively lowered; consequently, the lowest contraction rate can reach 0.04% and the lowest expansion rate can reach 0.1%; as the volume change of the composite floor board caused by expansion and contraction is greatly decreased, the use performance and the service life of the composite floor board can be effectively improved.

Description

technical field [0001] The invention relates to the field of floor production, in particular to a composite floor and a production method thereof. Background technique [0002] The specifications of calcium carbonate used in the base material layer of the existing composite flooring are all 325 meshes, which makes the shrinkage rate of the composite flooring produced can only reach a minimum of 0.05%, and the expansion rate can only reach a minimum of 0.13%. It is relatively large, and the quality of the composite floor is relatively poor. During use, it is easy to cause gaps between the floors due to thermal expansion and contraction or mutual extrusion between the floors, resulting in floor breakage and other damage, affecting the normal use of the floor. reduce its service life. Contents of the invention [0003] The object of the present invention is to provide a compound floor with low expansion rate and shrinkage rate and its production method in order to solve the ...
