Abstract
The invention discloses a unilateral enhanced ceiling adornment thistle board and a production technology thereof. When thistle boards are produced, a layer of short cutting glass fibres of 4 to 15mm length are evenly sprayed on plaster slurries before the plaster slurries and upper layer protective paper are compounded. Per square of thistle boards are sprayed with 0.2 to 1 kg of short cutting glass fibres so that the glass fibres are evenly spread on the upper surface of the plaster slurries, and then the glass fibres are ground and dried. Because the short cutting glass fibres are evenly sprayed between an upper thistle board protective layer and a plaster sandwich layer, the added short cutting glass fibres only need to satisfy the strength requirements on ceiling adornment materials of upper thistle boards. Thus, the invention avoids the drawback that large quantities of short cutting glass fibres are mixed in the sandwich layer so as to satisfy the strength in the prior art.
Description
Technical field
The invention belongs to plastering, relating in particular to is Thistle board in order to ceiling decoration.
Background technology
Thistle board is a kind of light-weight building thin plate, armour layer and the land plaster of centre and the sandwich layer layer structure that common compoiste adhering forms on forming machine that auxiliary agent is formed that it is made up of the protecting paper of gypsum board on both sides.Because it is characteristics such as it has environmental protection, lightweight, processing characteristics is strong, job practices is easy are widely used in various industrial construction and civilian construction, especially a large amount of as indoor partition material and ceiling ceiling material.But because the main raw material(s) of Thistle board is plaster of Paris and mask paper, these two kinds of materials all have certain moisture absorption, and after the two moisture absorption, rupture strength can descend.During especially as suspended ceiling decorative plate, owing to be mounted on the keel, its middle part is unsettled, and under action of gravity, ceiling decoration Thistle board bottom is in tension state all the time.After the ceiling decoration Thistle board moisture absorption, there is not the place of keel can be sagging gradually under action of gravity, influenced the ornamental of decorative panel.Though some manufacturers can reduce the auxiliary agent or the reinforcing material of material moisture absorption by add some in raw material, hope can solve the problem of the sagging distortion of Paper-faced gyp ceiling decoration sheet material, and effect is not ideal.
In order to improve the enhancing effect of Thistle board as ceiling decoration sheet material, some producers are when the preparation Paper-faced gyp, artificial laying layer of glass grid cloth in gypsum slip sandwich layer, make slip evenly be filled in the fiberglass gridding cloth through rolling, the defective that this enhancing mode exists is: in preparation process, need artificial the laying, can't realize that mechanization produces continuously.
For the mechanization that realizes the ceiling decoration Thistle board is produced continuously, occurred utilizing chopped strand to produce the technology that ceiling decoration strengthens gypsum plank in the market, just when the converted paper surface gypsum board, processing and forming is carried out in the even blending of chopped strand again in the gypsum slip, thereby form the three layer construction that the sandwich layer that formed by gypsum slip and chopped strand and two sides mask ply of paper are formed.The defective of its existence is: because Thistle board is in the ceiling decoration use, only the ceiling material towards the bottom is subjected to pulling force, ceiling material towards the top is not subjected to pulling force, if evenly blending chopped strand mode strengthens in the gypsum slip, the top of that ceiling material and the mechanical strength of bottom improve simultaneously, want the enhancing effect that top and bottom all reach simultaneously to be needed, and need the abundant chopped strand of admixture, cause unnecessary waste, cost is higher.
Therefore, it is imperative to invent a kind of cost Paper-faced gyp ceiling decoration sheet material lower, that can mechanization produce
Summary of the invention
The present invention strengthens the ceiling decoration gypsum plank and can't mechanization produce continuously and chopped strand enhancing ceiling decoration gypsum plank cost technical problems of high for solving existing fiberglass gridding cloth, provide a kind of cost lower, can the one-sided enhancing ceiling decoration of mechanization quantity-produced Thistle board.
The present invention provides the production technology of this Thistle board simultaneously.
For achieving the above object, ceiling decoration Paper-faced gyp plated construction of the present invention is: it comprises the armour layer of the protecting paper of gypsum board composition on land plaster slip sandwich layer and both sides, it is characterized in that, between upper strata gypsum plank armour layer and slip sandwich layer, spray the short glass fiber enhancement layer that has 4-15mm long.
Above-mentioned short glass fiber is the commercial anti alkali containing glass fibre,
Ceiling decoration Thistle board preparation method of the present invention is: when producing Thistle board, before gypsum slip and upper strata mask paper are compound, on the gypsum slip, evenly spray the long short glass fiber of one deck 4-15mm, general every square metre of Thistle board sprays short glass fiber 0.2-1kg, make glass fiber be dispersed in gypsum slip upper surface, after rolling, drying, just made one-sided enhancing Thistle board.Other technological parameters do not change after spraying glass fiber.
During use, technology applies the mask paper surface that strengthens a side through glass fiber or the pad pasting processing routinely, cuts into given size then and gets final product.
During installation, the armour layer that needs to add glass fiber one side down because the short glass fiber that evenly is scattered here and there in the ceiling material bottom has just strengthened the tensile strength of gypsum ceiling material bottom, the sagging distortion that has alleviated ceiling material.
Advantage of the present invention is:
1, because short glass fiber is evenly to be sprayed between upper strata gypsum plank armour layer and the slip sandwich layer, as long as above the slip at existing mask paper paper bowl place, Paper-faced gyp board assembly line upper strata, increase a short glass fiber injection apparatus, can realize mechanization production.
2, owing to just between upper strata gypsum plank armour layer and slip sandwich layer, evenly spray short glass fiber, so as long as the short glass fiber that adds can make upper strata gypsum plank suspended ceiling decoration material satisfy requirement of strength, avoided prior art to need the defective of a large amount of short glass fibers of blending in sandwich layer because of satisfying intensity.Through test, reaching under the identical enhancing effect, the glass fiber amount that the present invention need add is than existing ceiling decoration Thistle board minimizing 60%, and cost of production reduces greatly.
In a word, the invention provides and the different technical scheme of prior art design, though technology is simple, under the prerequisite that improves rupture strength, cost of production reduces greatly but compared with prior art,, save the energy, met current country-driven low-carbon economy policy, had obvious improvement.
Description of drawings
Fig. 1 is the section front view of ceiling decoration gypsum plank of the present invention.
Among the figure: the last mask ply of paper of 1-, 2-glass layer, 3-slip sandwich layer, mask ply of paper under the 4-.
The specific embodiment
Further specify technical scheme of the present invention below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, ceiling decoration Thistle board of the present invention is a four-layer structure, be followed successively by mask ply of paper 1, glass layer 2, slip sandwich layer 3 and following mask ply of paper 4 from top to bottom, thereby form one-sided enhancing Thistle board, meet the requirement that Thistle board uses as suspended ceiling decoration material.
Processing method is: at first mask paper paper bowl place increases a short glass fiber injection apparatus on existing gypsum board production line, in the process of producing Thistle board, after gypsum slip core enters forming machine with following mask ply of paper 4 (before the mask paper of just also not compound upper strata), utilize injection apparatus on slip sandwich layer 3, to spray short glass fiber layer 2, compound with last mask ply of paper 1 subsequently, carry out moulding oven dry etc. again, just be processed into one-sided glass and strengthened Thistle board.
During use, will go up again that mask ply of paper 1 applies or pad pasting is handled, cut into given size, and promptly can be made into glass and strengthen the Paper-faced gyp suspended ceiling decorative plate.
