Abstract
The present invention relates to the laminar product field, is a kind of porcelain board and manufacturing process thereof that can replace wooden Baoli polywood laminate.Porcelain board has light-shielding agent, facing paper or plastic film and sheet billet three layer construction, and its manufacturing process is: batch mixing and glass fabric are replaced lay, dry moulding and get sheet billet, carry out incrustation then and handle.Contain (weight %) magnesia 50-70, magnesium chloride 10-20, French chalk 0-25, flake asbestos 3-5, high alumina cement 0-20, inorganic additive 3-10 in the batch mixing.The present invention have various physics, chemical property near or be better than wooden Baoli polywood laminate and production technology simply, easily construction and advantage such as inexpensive.
Description
The present invention relates to the porcelain board and the manufacturing process thereof in laminar product field, particularly a kind of alternative wooden Baoli polywood laminate.
Chinese patent 91106605.5 disclosed " magnesium fibre board and manufacture method thereof ", be to be the batch mixing matrix material with magnesia, magnesium chloride, French chalk, short glass fiber, swelling perlite powder are evenly mixed batch mixing with the batch mixing matrix material, and layering adds glass fabric when making magnesium fibre plate.Because selection is unreasonable, so following defective arranged: the one, adopt glass fiber as reinforcement material after, because of glass fiber self tangles agglomerating easily, be difficult to be evenly dispersed in and make among the raw material, not only make operating difficulties, also be difficult to realize suitability for industrialized production, and the sheet material of producing is still thicker.The 2nd, selected too much anti-water substance for use, as sulfuric acid, oxalic acid, phenol, natrium nitrosum and ferrous sulfate etc., thus troublesome poeration not only, and cost is improved.The 3rd, decoration functions is poor, and color and luster is few and can not carry out the surface and handle (as doing decorative pattern) again, can only be with wooden plywood or fiberboard ratio, and of low grade.
The objective of the invention is provides a kind of porcelain board and manufacturing process thereof at above-mentioned defective, compares with wooden Baoli polywood laminate, and not only its manufacturing process is simple, and water absorption rate is low and have stronger fire-retardant, an antiacid caustic corrosion performance.
The object of the present invention is achieved like this: with magnesia, magnesium chloride and French chalk is base-material, to make batch mixing behind flake asbestos, inorganic additive and high alumina cement and the base-material mixing, replace lay with glass fabric again, dry moulding and get sheet billet, on sheet billet, carry out incrustation then and handle.The percentage by weight of each component is in the batch mixing: magnesia 50-70, magnesium chloride 10-20, French chalk 0-25, flake asbestos 3-5, high alumina cement 0-20, inorganic additive 3-10.
According to the prepared porcelain board of such scheme, its structure is: the upper strata is a light-shielding agent, and the intermediate layer is facing paper or plastic film, and bottom is above-mentioned sheet billet.Light-shielding agent is phenolic resins or or unsaturated polyester resin.
The incrustation treatment process is in the such scheme, can be earlier pastes one deck facing paper or plastic film at sheet billet, sprays after drying again or is coated with one deck light-shielding agent, promptly gets the porcelain board finished product after air dry.
The effect of each component is in the above-mentioned batch mixing: magnesia and magnesium chloride form magnesia oxychloride cement, French chalk is a filler, flake asbestos is a reinforcing material, inorganic additive such as sulfuric acid or sulfuric acid and ferrous sulfate mixture or phosphoric acid can improve the doing of slab, wet strength and fixedly chlorion to reach the purpose that improves intensity.
The invention has the advantages that: the one, production technology is simple, construction easily, this is because the result that asbestos fiber did not tangle, do not become bulk in process of production and disperses easily.The 2nd, process simpler than wooden Baoli polywood laminate, can save scrape ash, polishing etc. time-consuming, the effort operation.The 3rd, product specification height, porcelain board have the decoration functions and the range of application of wooden Baoli polywood laminate and glass fiber reinforced plastics product.The 4th, various physics, chemical property are better than or approaching wooden Baoli polywood laminate, as resistance to compression, the approaching wooden Baoli polywood laminate of anti-MOR, anti-flammability, acid-alkali-corrosive-resisting performance and water repellency (water absorption rate about 3.5%) etc. are better than wooden Baoli polywood laminate, and the use aspect can paste in several ways, process, and wooden Baoli polywood laminate is easier than using.The 5th, be no more than two kinds of inorganic additives (generally only selecting for use sulfuric acid or phosphoric acid to get final product) owing to produce easy, easy to process and only select for use, so cost of production and price are lower.
In a word, porcelain board provided by the present invention and manufacturing process thereof are a kind of regeneration product and the production technologies that can promote easily and be worthy to be popularized and can replace wooden Baoli polywood laminate at building material industry.
The invention will be further described below in conjunction with embodiment:
Porcelain board provided by the present invention is made up of light-shielding agent, facing paper or plastic film and sheet billet three layer construction.Sheet billet is to replace lay on glass plate or poly (methyl methacrylate) plate by batch mixing and glass fabric, it is the layer overlay batch mixing, thickness is 1mm, be covered with layer of glass cloth, clap to press and make it to combine closely with batch mixing, both thick approximately 1.5mm repeat above operation again, and the number of times that is repeated can be decided the thickness requirement of product according to market; Under room temperature, keep flat about 8 hours of spontaneous curing then, remove template, keep flat, air dry 3-4 days again.Light-shielding agent can be selected phenolic resins or unsaturated polyester resin for use.
On sheet billet, carry out incrustation handle the back porcelain board, its activities is, on the sheet billet smooth surface, brush a layer binder earlier, be covered with facing paper or plastic film, use the rubber roller roll extrusion, make it to combine with slab tight, smooth, air dry (curing) is after 4 hours, on film the spray or be coated with one deck light-shielding agent, promptly become porcelain board again after the air dry.Incrustation is handled and also can be realized by spray, painting or coating.
Each amounts of components (weight %) sees the following form in the batch mixing, and listed five kinds of scheme effects all can in the table.
