Embodiment 1

[0018] A manufacturing process for a 7mm geothermal floor base material, comprising the steps of:

[0019] 1. Fiber preparation. After washing the self-cut wood chips or purchased wood chips obtained by the screening, they are subjected to cooking treatment, and the cooked wood chips are subjected to thermal grinding treatment to obtain the required fibers;

[0020] 2. Adjust the glue, spray diphenylmethane diisocyanate (purchased from Huntsman) and emulsified paraffin evenly on the fiber respectively, wherein the addition of diphenylmethane diisocyanate (MDI) is 4%, remove The addition amount of molding agent is 0.5%, and the addition amount of emulsified paraffin is 1%;

[0021] 3. Drying, drying the fiber after sizing and waxing, the moisture content of the dried fiber is 11-12%;

[0022] 4. Add additives. In the fiber air duct, spray the mixture of additive alumina powder and carbon fiber powder evenly on the dried fibers, wherein the amount of alumina powder added is 6% ...

Abstract

The invention belongs to the technical field of beaver board production and relates to manufacturing of floor base materials, in particular to a manufacturing technique for a geothermal floor base material and the base material. According to the manufacturing technique for the geothermal floor base material, the production technological process comprises the steps of wood chip forming, screening, water washing, stewing, hot grinding, applying of a non-formaldehyde adhesive and a waterproof agent, drying, applying of additives, paving, prepressing, hot pressing, cooling and grading packaging. According to the manufacturing technique for the geothermal floor base material, by adjusting the adhesive applying technique, aluminum oxide and carbon fiber powder are added in fibers, and thus the manufactured floor base material is free of formaldehyde and good in water resistance. The heat conductivity and size stability of the geothermal floor base material are improved, the hidden danger that formaldehyde pollution is released in the using process of composite geothermal floors is eliminated, the problems of deformation, arching, open joint contraction and the like during usage of the composite floors are reduced, the heat conductivity and the heat insulation of the geothermal floors are improved, and the energy consumption is reduced.

Description

technical field [0001] The invention belongs to the technical field of man-made fiberboard production, and relates to the manufacture of floor substrates, in particular to a manufacturing process and substrate for geothermal floor substrates. [0002] Background of the invention [0003] With the acceleration of the aging process of Chinese society and the extreme weather caused by global climate anomalies, the difficult winter in the vast areas south of the Yangtze River has brought relatively big troubles to consumers. Geothermal flooring for home improvement will be the first choice in China's wood flooring industry. The general trend. Geothermal floor refers to the floor that is suitable for laying ground radiant heating system, and transfers heat to the room through the board. The types mainly include solid wood floor and laminated floor. At present, geothermal wood floors generally have disadvantages such as inconspicuous heat feeling, slow heating, and slow cooling. I...
