The invention discloses a deformation-resistant composite floor base material which comprises a bottom plate, a surface plate, a core plate and four side plates. The core plate sequentially comprises an upper layer, a middle layer and a lower layer from top to bottom. Fibers webs are laid between the upper layer and the middle layer as well as between the middle layer and the lower layer. Each fiber web is provided with two slim tubes extending upwards in the vertical direction and two slim tubes extending downwards in the vertical direction. The slim tubes communicate with interiors of grid lines of the fiber webs. Two through holes are horizontally formed in each side plate. The axis of each through hole and the corresponding fiber web are located on the same plane. The side face, close to the core plate, of each side plate is provided with round grooves. The slim tubes finally communicate with the through holes through the fiber webs and the round grooves, and thus air ventilation paths are formed. The deformation-resistant composite floor base material is simple in production technique, good in ventilation performance and air permeability, firm, resistant to pressure and high in deformation resistance, and the deformation resistance of the deformation-resistant composite floor base material is improved by 40 times compared with that of a traditional composite floor base material.
Description
technical field [0001] The invention relates to the field of composite floors. More specifically, the present invention relates to a deformation resistant laminate flooring substrate. Background technique [0002] As a decorative material, composite flooring is widely used in people's life and work. Moreover, with the improvement of people's material living standards, people's demand for composite flooring is increasing, and their quality requirements are also getting higher and higher. . The base material is the main body of the composite floor, which plays an important role in the tongue-and-groove connection, stable shape, and load bearing in actual use. The quality of the base material will directly affect the quality of the composite floor. [0003] The base material constitutes the main body of the composite floor, and plays an important role in tongue and groove connection, stable shape, and load bearing in actual use. The quality of the base material will directly ...
