Embodiment 1

[0026] Example 1: A scratch-resistant and sound-insulating leather wallboard, which includes, from top to bottom, scratch-resistant flexible leather weaving cloth, PVC sheet A, polymer sound-insulating felt, PVC sheet B and mute mat; PVC sheet A and PVC sheet B is a stone-plastic plate, in which the mass ratio of PVC powder and calcium powder is 1:2.5 to 1:3.3.

[0027] Its preparation method comprises the following steps:

[0028] S1. Preparation of scratch-resistant flexible plywood fabric, three-layer coating on the surface of the sandwich cloth: primer layer, middle-coat foam layer, and top-coat scratch-resistant layer;

[0029] S2. The preparation of PVC sheet material A and PVC sheet material B, adopts twin-screw extruder to produce the PVC sheet material A and PVC sheet material B that thickness is 2~5mm;

[0030] S3. Lay the scratch-resistant flexible leather textured cloth, PVC sheet A, polymer sound insulation felt, PVC sheet B and mute mat in sequence, and stick th...

Abstract

The invention belongs to the technical field of plate manufacturing, and relates to a composite wallboard, in particular to a scratch-resistant sound-insulating leather wallboard. The wallboard is technically characterized by sequentially comprising scratch-resistant flexible leather pattern woven fabric, a PVC plate A, a high-molecular sound-isolating felt, a PVC plate B and a mute pad from top to bottom. The preparation method specifically comprises the following operation steps of S1, preparing the scratch-resistant flexible leather woven fabric; S2, preparing the PVC plate A and the PVC plate B; and S3, flatly laying the scratch-resistant flexible leather woven fabric, the PVC plate A, the high-molecular sound-isolating felt, the PVC plate B and the mute pad in sequence and attached the same through PUR glue. The scratch-resistant sound-insulating leather wallboard has the advantages of wear resistance and scratch resistance, meets the requirements of high performance, high quality and excellent transmission loss, achieves the requirements of water resistance, sound insulation, wear resistance, scratch resistance and style diversification, and has the application value.

Description

technical field [0001] The invention belongs to the technical field of plate manufacturing, and relates to a composite wallboard, more specifically to a scratch-resistant and sound-insulating leather wallboard. Background technique [0002] Noise refers to the sound made when the sounding body vibrates irregularly, which is a common environmental pollution. Noise pollution is formed when noise has adverse effects on people and the surrounding environment. Since the industrial revolution, the creation and use of various mechanical equipment has brought prosperity and progress to human beings, but at the same time it has also produced more and more noise. Noise will not only cause hearing damage, but also induce a variety of cancer-causing and fatal diseases, and also interfere with people's life and work. Therefore, more and more attention has been paid to sound-insulating materials that can isolate, isolate, and separate the noise transmitted in the air. For sound insulat...
