Manufacturing process of super-wear-resistant sound-absorbing soft floor

Abstract

The invention discloses a manufacturing process of a super-wear-resistant sound-absorbing soft floor and belongs to the technical field of plate processing. The preparation method comprises the following steps of: S1, mixing: uniformly mixing straw sections, a glue solution, an additive and other components; S2, heating: transferring the uniformly mixed materials into a heating tank body to heat the materials into a semi-fluid molten state; S3, extrusion: transferring the semi-fluid into an extruder, and extruding the semi-fluid into a strip-shaped body; S4, primary rolling:directly connectingthe strip-shaped body into a pressing roller unit to roll the strip-shaped body into a sheet-shaped soft base plate; S5, secondary rolling: rolling a cloth fiber layer and a sound absorption layer onthe upper surface and the lower surface of the soft base plate by a compression roller unit to form a soft rolling-formed glue permeation plate; S6, stacking: stacking the soft rolling-formed glue permeation plate, a decorative layer and a wear-resisting layer in sequence; and S7, pressing: arranging the soft rolling-formed glue permeation plate, the decorative layer and the wear-resisting layerin a pressing machine after stacking the same, so as to press and compound the soft rolling-formed glue permeation plate, the decorative layer and the wear-resisting layer to obtain the super-wear-resistant sound-absorbing soft floor. Under the buffer type synergistic effect of the soft base plate and the wear-resisting layer, the wear resistance of the whole plate is improved, and the technical effect of super wear resistance is achieved.

Description

technical field [0001] The invention belongs to the technical field of plate processing, and more specifically relates to a manufacturing process of a super wear-resistant sound-absorbing soft floor. Background technique [0002] my country is a large agricultural country with abundant crop straw resources, with an annual output of about 700 million tons of straw, ranking first in the world. In recent years, with the rapid development of my country's economy, the rural energy structure has undergone significant changes. The traditional demand for using straw as living fuel has decreased year by year, resulting in the accumulation of most of the remaining straw. As a natural cellulose fiber, straw fiber has good biodegradability and can become an environmentally friendly product. Not only are these resources not being well utilized at present, but we can see the burning smoke in the fields every summer and autumn. These fumes bring inconvenience to people's life and work, g...

Problems solved by technology

[0008] Aiming at the problems of high production cost of composite wood flooring in the prior art, prone to glue-opening and deformation, and poor impact resistance, wear resistance, and sound insulation effect, the present invention provides a super wear-resistant and sound-absorbing soft floor The technology makes full use of the temporary storage effect of the straw section on the glue, and has the technical effect of slow release of the glue, so that the glue is released in the subsequent rolling and pressing process, and the sound-absorbing layer and the decorative layer are not required before compounding. Under the premise of dipping, the three are pressed and compounded to avoid glue opening and deformation. Moreover, combined with the cushioning effect of the soft substrate, the impact resistance is improved, and under the synergy of the wear-resistant layer cushioning, the wear resistance of the entire board is improved. It has a super wear-resistant technical effect, and the composite sound-absorbing layer can absorb noise, thus avoiding mutual interference between floors
