Abstract
The present invention relates to a decorative composite board for building and its preparation method. It is characterized by that it uses magnesium oxide and magnesium chloride as raw materials, uses stone-boring powder or saw dust as filler, uses light calcium carbonate as neutralizing agent, uses unsaturated resin, hardening agent and promoter to prepare a binding hardening agent and uses glass-fibre cloth as reinforcing material, and makes the above-mentioned materials pass through such processes of material mixing, casting, molding, pressing, solidifying and drying in the air so as to make the above-mentioned materials into sheet materials with various specifications and various decorative products.
Description
The present invention relates to building decorative composite board and preparation method thereof.
Along with the raising of living standards of the people and the development of urban and rural buildings cause, the building and the demand of finishing material increase severely day by day, are exactly the building and ornament materials of large usage quantity wherein as three-ply-wood, and it not only consumes a large amount of timber, and price rises year by year, need bring certain difficulty to the people, the present also a large amount of three-ply-wood of import, same price height, also the someone has studied a kind of composition board without timber for this reason, this composite sheet toughness is bad, can not repeat nailing, scrapes, dig, and the bonding difficulty is bigger.
The objective of the invention is to overcome the shortcoming of above-mentioned prior art with not enough, and provide a kind of good toughness, composition board that intensity is high and preparation method thereof, also can be prepared into the building decoration articles for use and the domestic life goods of different shape, thereby save a large amount of timber, also increased the kind of building and ornament materials goods.
The object of the present invention is achieved like this:
Building decorative composite board, comprise main raw material, casting resin, neutralizing agent, adhesive solidification agent, strongthener, it is characterized in that main raw material adopts magnesium oxide, magnesium chloride, moth stone flour or sawdust are adopted in casting resin, neutralizing agent adopts light calcium carbonate, the transparent colloid of being made through solidifying agent and promotor by unsaturated polyester is adopted in the adhesive solidification agent, and glasscloth is made strongthener, and various material consumptions are (weight %).

Wherein the unsaturated polyester solidifying agent is any one of cyclohexanone, cycloethanone peroxide slurry, benzoyl peroxide, and promotor is any one of cobalt naphthenate solution, xylidine.
Magnesium chloride raw material content of magnesium chloride is more than 45%, better effects if.
The granularity of raw materials of magnesium oxide is selected for use below 120 orders.
The preparation method of composition board of the present invention, comprise slip preparation, cast, moulding, compacting, solidify, dry, it is characterized in that:
A) magnesium oxide, moth stone flour or sawdust are mixed, stir body in the pasty state, add the light calcium carbonate neutralization reaction again and continue and stir with magnesium chloride brine;
B) in unsaturated polyester, add promotor again behind the adding solidifying agent, stir, make transparent colloid;
C) (a) material is added in (b) material, make the slurry of composition board through stirring;
D) slurry of upper berth, end layer of glass cloth (thick 1.5mm) back injection (c) item in mould, topped again layer of glass cloth is used greater than the polyester film paper of mould topped at last;
E) flatten with artificial or machinery, flatten with the rubber roll machine again, add the paper film again and continue to flatten and flatten;
F) after solidifying, remove the paper film, demoulding promptly makes finished product after drying.
Wherein the density of magnesium chloride of magnesium chloride brine is more than 30%.
Setting time is 4-8 hour.
Composite board material of the present invention can be made the building and the adornment of different shape.
Owing to take technique scheme, make the technology of the present invention have following advantage and effect:
A) toughness of products is good, reaches the three-ply-wood standard, and the ultimate compression strength height can repeat nailing, and the energy scraper plane;
B) water-intake rate is low, do not burn, and without putrefaction, sound insulation is good, and acid and alkali-resistance is anti-aging, and the life-span is long; The moth stone flour is done not conducting heat of casting resin making;
C) raw material sources are wide, and some raw material is utilization of waste material, and is pollution-free;
D) preparation method is easy, and throughput is big;
E) purposes is wide, can be made into the building and ornament materials articles for use of different shapes different size.
