Facing bamboo plastic heat conduction wallboard with negative ions and processing method thereof

Abstract

The invention discloses a facing bamboo plastic heat conduction wallboard with negative ions and a processing method thereof. The facing bamboo plastic heat conduction wallboard is characterized by comprising a bamboo plastic wallboard substrate layer, a glass fiber cloth layer, and a reconsolidated bamboo veneer layer. The bamboo plastic wallboard substrate layer comprises the following components by mass: 20-25% of bamboo powder, 30-35% of a PVC and polyether block amide blend, 8-10% of nanoscale bamboo charcoal powder, 2-4% of a lubricant, 1-3% of a foaming agent, 2-3% of a coupling agent, and the balance germanite powder. The wallboard provided by the invention adopts bamboo processing waste, germanite powder, thermoplastic plastics (PVC and polyether block amide blend) as the main raw materials, and the facing bamboo plastic heat conduction wallboard with negative ions is manufactured by crushing, pretreatment, high-speed mixing, extrusion, curing, gluing, assembling compounding, cold pressing, sanding, painting, slotting and other processes. The wallboard has natural texture, high negative ions and heat conduction efficiency, and low thermal expansion coefficient, is not easy to warp, can be widely used in the field of functional wallboards, and has good market prospects.

Description

technical field [0001] The invention relates to a facing bamboo-plastic composite material, in particular to a construction method of a facing bamboo-plastic heat-conducting wallboard with negative ions. Background technique [0002] Negative ions can not only promote the synthesis and storage of vitamins in the human body, strengthen and activate the physiological activities of the human body, but also have the effect of purifying the air and anti-oxidation. Therefore, negative ions are also known as "air cellulose". Germanium stone is a general term for a type of ore containing germanium in nature. Ochre is cheap and rich in mineral resources. The negative ions released by germanium stone can make people clear-headed, quickly recover from fatigue, expand blood vessels, relieve arterial vasospasm, and improve cardiovascular and cerebrovascular systems. , Nervous system, respiratory system and other diseases have obvious improvement effect. After the ocher is heated, variou...

AI Technical Summary

Problems solved by technology

However, as an important wallboard in the home environment, ordinary foamed wood-plastic composite materials are basically used, which do not have the requirements of excellent natural texture, thermal conductivity, thermal stability, good deformation resistance, excellent mechanical properties and good environmental protection.

In addition, the wood-plastic wallboards currently on the market are usually made of plant fibers and thermoplastics with related additives, melt blended and extruded, and have poor interface compatibility between wood fibers and thermoplastics, low thermal conductivity, and small size. Poor stability, easy warping and other problems, can only be used as ordinary home wall panels, and cannot meet the growing needs of functional wall panels

[0004] At present, there is no bamboo-plastic heat-conducting wallboard with added germanium in the market.
