Description

A kind of interior enhancing composite board made using Chinese medicine dreg and preparation method thereof

Technical field

The invention discloses a kind of composite board, is answered more particularly to a kind of interior enhancing made using Chinese medicine dreg Plywood material and its production method.

Background technology

In many occasions such as office building, auditoriums, hotels, telecommuting, municipal gardens, often using various floorings, railing, wallboard, phase Frame, picture frame, skirting, withhold the products such as plate, traditionally, these products be generally plank, plastic plate, marble slab etc. make and Into, but these plates have some limitations during production or use, such as, plank is easy to crack, easily damages by worms, cost Height, and need to fall trees in process, it is unfavorable for water and soil conservation and environmental protection;Plastic plate degradability is poor, discards The waste material produced afterwards will pollute the generations such as soil, water body, and yielding, colour fading easy to aging of plastic plate etc. mostly;Marble slab Heaviness, transport, installation are inconvenient, and sense of touch is poor, and modifiability is poor etc..In recent years, the research of wood plastic composite is with answering With the concern for receiving height, it has excellent anti-corrosion and waterproof, anticracking and antifouling property, without secondary operation, installation side Just, without toxic chemicals, low-carbon environment-friendly, without japanning, polishing, easy to maintain, more easy to clean, heat-insulating sound-insulating etc., thus It is various to can be widely applied to interior/exterior decoration, Garden Engineering construction, workshop antiseptic project, marine anticorrosion engineering, environment sanitation facility etc. Occasion.But at present production wood plastic composite used in plant fiber substantially on all use wood powder or bran powder, using wood powder without Substantial amounts of timber will be expended by doubting, and China's timber resources is in short supply, and annual timber supply and demand notch is up to 60,000,000 m3;And bran powder source It is relatively in short supply, and be the important feed of domestic animal, it is a large amount of to be equivalent to take grain by force from domestic animal mouthful using bran powder.So utilize it The fiber powder of his resource makes the forward position that wood plastic composite is countries in the world research, and necessity of China's wood moulding industry development Approach.

China is Chinese medicine production and is expected its Chinese Medicine Industry annual growth in 20- using big country, whole nation major part provinces and cities Between 25%, drug in some provinces is estimated more than 30%, and Chinese herbal medicine industry is quickly grown.It will be produced during Chinese medicine is prepared a large amount of solid Body Chinese medicine dreg, traditionally, these Chinese medicine dregs are abandoned generally as discarded object or burnt as fuel, resource wave Take than more serious.

So substituting traditional plant fiber production wood plastic composite using discarded Chinese medicine dreg, it can meet market Needs, while can also turn waste into wealth, it is very necessary.

The content of the invention

It is an object of the invention to the Chinese medicine dreg of China's abundant is carried out recycling recycling, there is provided one kind utilizes Chinese medicine The interior enhancing composite board and its production method that the dregs of a decoction make.

A kind of interior enhancing composite board made using Chinese medicine dreg, takes following scheme to realize:

A kind of interior enhancing composite board using Chinese medicine dreg making is porous by three layers of thermoplastic composite layer and two layers Same with thermosetting compound material layer is formed, and is one layer of porous same with thermosetting compound material layer per between two layers of thermoplastic composite layer.

Three layers of thermoplastic composite layer composition and structure are identical, by polyolefin plastics particle, Chinese medicine dreg, horse Come acid anhydrides, stearate, antioxidant, alkali magnesium sulfate crystal whisker and microcrystalline cellulose through mixing, extruding, rolling and form;More than two layers Hole same with thermosetting compound material layer composition and structure are identical, by unsaturated polyester resin, naphthoic acid cobalt, methyl ethyl ketone peroxide, Chinese medicine dreg and burlap handle paste, molding and drill, surface galling, alkaline etching form.
