Abstract
The present invention relates to a manufacturing method for high-strength water-resisting artistic plaster bricks and boards. The present invention uses calcined gypsum powder, pearlite powder and water as raw materials to prepare face materials and bottom materials in definite proportions; 30% of weight of product volume of the face materials and 70% weight product volume of the bottom materials are orderly put into a steel mould which pads a pattern plate, and the face materials and the bottom materials are sent into a press to carry out extrusion forming; after demoulded, products are conserved for 2 hours under hygroscopic state and are set for 24 hours under still state to prepare to be used. Compared with the gypsum products of the prior art, the gypsum products produced by the present invention has the advantages of high intensity, water resistant, wear resistant, low cost, simple producing process and less equipment investment.
Description
The invention relates to the manufacture method of a kind of high-strength light artistic plaster bricks, plate, relate to the gypsum building material production technical field.
Current, raising along with China's living standards of the people, people require also progressively to improve to the finishing of various interior of buildings, gypsum brick, plate are used widely day by day as a kind of building and ornament materials, but known in the past production method is that gesso is mixed with glass fibre, water etc., and adding poly-vinyl alcohol solution, after fully stirring, putting into rubber mold evens up, leave standstill the demoulding after 15-20 minute, put into nursing frame and send into drying oven, thermostatic curing 24 hours or dry in the sun under 80 ℃ temperature just can use.Because the weight ratio of gesso and water reaches 1: 0.8-0.85, so plastering moisture content height, gypsum is comparatively full to be closed, packing is poor, intensity is low, and is easily broken, after particularly making moist, easy deformation, sagging and warpage often takes place in the plastering that finishing is good, has a strong impact on decoration quality, though can add organic emulsified wax in process of production, sodium methyl silicate and so on waterproofing agent, but reduced the intensity of plastering significantly.
The Chinese invention patent communique on February 18th, 87 disclosed a " a kind of production method of plasterboard " application (CN85106288A), and the method that has proposed to mix granular strengthening material and delayer or accelerator in the plaster of paris reduces the method for water paste ratio.
The production method that the purpose of this invention is to provide a kind of high-strength, water-fast, artistic plaster bricks, plate, the plastering that uses this method to produce has high-strength, water-fast characteristics, and need not add the number of chemical additive in the production process, does not also need thermostatic curing.
The method applied in the present invention is to carry out according to the principle of plaster of paris energy hydration and hardening and ageing mechanism, and it has solved the plaster of paris is difficult to moulding under the situation of few moisture problem.Its production method is undertaken by production stage shown in the drawings.At first be batching, batching be divided into again preparation lining and bed material, lining adopt gesso and water by 1: 1 weight ratio mixing and stirring form, bed material adopts gesso and crushed crude pearlite forms by 10: 1 weight ratio mixing and stirring; Be the dress mould subsequently, dress is during mould, and 30% the lining that will account for the plastering volume weight is earlier put into the steel mould that is lined with the decorative pattern template and evened up, and the bed material of plastering volume weight 70% is put on the steel mould inner facing material evened up again; Be compacting then.Steel mould after the dress mould finishes can be sent into compression moulding in the forcing press, the pressure of forcing press is controlled between 7.5～10T, the plastering that suppresses through forcing press gets final product the demoulding, be placed on the nursing frame maintenance 24 hours, maintenance is better under wet condition, and plastering at this moment can use, but dries back using and transport more favourable plastering, because weight can alleviate, also cracky not.
Accompanying drawing is a production stage of the present invention.
The embodiment of the invention: make 200 * 200 * 6mm
3Gypsum brick, the plate of size, granularity 100 purpose gessoes and water are prepared bed material by 1: 1 the weight ratio preparation lining weight ratio that the crushed crude pearlite about 0.6～1.0mm was pressed 10: 1 with same gesso and granularity again, subsequently lining and bed material are successively put into steel mould by 3: 7 lining of product volume weight and bed material, send into the compressor compacting, press pressure is controlled at 10T, the demoulding, put on the nursing frame maintenance 24 hours, makes the heavy 6-7kg/m of plastering
2Gram, intensity is 20-50kg/cm
2
Gypsum brick disclosed by the invention, slab products production method operation are simple, and equipment investment is few, production cost is low.The plastering lightweight of producing, water-fast, aging, humidity in all right conditioning chamber, thereby be a kind of comparatively desirable production method.
Claims (1)
1, a kind of water-resisting artistic plaster bricks, board fabrication method is that raw material carries out through batching, dress mould, compacting, four sequence of steps of maintenance with gesso, perlite, water, it is characterized in that:
A. batching be divided into preparation lining and bed material, lining with gesso and water by 1: 1 weight ratio prepare, bed material prepares by 10: 1 weight ratios with gesso and crushed crude pearlite;
B. adorning mould is the steel mould of earlier lining being packed into, on the lining in the steel mould of then bed material being packed into.
