Problems solved by technology

In order to achieve protection against static electricity, conductive materials coated with antistatic coatings are usually placed on the surface of the material, but due to its long-term use, the conductive material is prone to wear and tear, so that the material loses the antistatic effect

Embodiment 1

[0044] An antistatic poplar veneer decorative material is manufactured through the following steps:

[0045] Step 1: Cut the fast-growing poplar into veneers with a thickness of 4.0mm;

[0046] Step 2: Use a softening device to roll the tight surface of the poplar veneer to eliminate internal stress and make the cracks on both sides of the veneer consistent, which is conducive to the uniform penetration of resin;

[0047] Step 3: Dry the softened veneer to make the moisture content 10%;

[0048] Step 4: Mix 300-mesh graphite powder, 200-mesh silicon dioxide, and aluminum oxide at a mass ratio of 1:1 to obtain a composite wear-resistant agent, titanate coupling agent, aluminate coupling agent, and silane coupling agent. The composite additives obtained by compounding the joint agent at a mass ratio of 1:1:1 are evenly mixed, and are uniformly dispersed into the melamine resin with a solid content of 30% by air blowing and mechanical stirring to obtain a uniform dispersion and ...

Embodiment 2

[0057] An antistatic eucalyptus veneer decorative material is manufactured through the following steps:

[0058] The first step: slice the fast-growing eucalyptus into veneers with a thickness of 6.0mm;

[0059] Step 2: Use a softening device to roll the tight surface of the poplar veneer to eliminate internal stress and make the cracks on both sides of the veneer consistent, which is conducive to the uniform penetration of resin;

[0060] Step 3: Dry the veneer after softening treatment by traditional drying process, and control the moisture content at 8%;

[0061] Step 4: Mix 250-mesh metal powder (nickel powder or copper powder), 200-mesh silicon dioxide and aluminum oxide at a mass ratio of 1:1 to obtain composite wear-resistant agent, titanate coupling agent, aluminate The composite additive obtained by compounding the ester coupling agent and the silane coupling agent at a mass ratio of 1:1:1 is uniformly mixed, and is uniformly dispersed into the melamine resin with a ...

Abstract

The invention provides an antistatic wood material manufacturing method simple in technology and equipment. An antistatic wood decorative material prepared through the method is excellent in antistatic performance, high in surface hardness and good in abrasion resistance, the surface resistivity of the antistatic wood decorative material is 1.0E+5omega-1.0E+6omega, and the volume resistivity is 1.0E+5omega.cm-1.0E+6omega.cm; unhealthy phenomena such as dust absorption and electro-discharge caused by static charge accumulation in the using process of the material can be avoided, and the surface abrasion resistance reaches 6000 r or larger; and the antistatic wood decorative material can be widely applied to surface decoration of high-end office buildings, intelligent office blocks and other occasions of which the requirements for antistatic performance and abrasion resistance are high. The manufacturing method comprises the steps of base material preparation, softening treatment, drying treatment, antistatic resin preparation, primary impregnation, predrying, medium-high temperature compression treatment, secondary impregnation, secondary drying and the like. An antistatic agent, an abrasion-resistant agent and other assistants are evenly mixed and then dispersed into low-molecular-weight melamine resin used for impregnation, so that antistatic resin is formed.

Description

technical field [0001] The invention relates to a novel wooden decorative material with antistatic function and a manufacturing method thereof, belonging to the field of wood composite material manufacturing. Background technique [0002] The natural pattern and natural color of wooden decorative materials can create a relaxed, cheerful and elegant atmosphere, and have a strong affinity with human beings. It has always been one of the decorative materials that people must choose. [0003] Existing wood decoration materials mainly include decorative veneer, artificial veneer, wood-based panels, wood moldings and wooden floors, among which decorative wood-based panels and wooden floors have the most varieties and designs, and are the most widely used. Wooden materials are poor conductors of electricity, and the surface is prone to charge accumulation, forming static electricity. Especially after the surface of the material has been treated with paint coating or impregnated pa...
