Abstract
The invention discloses an integrally-enhanced gypsum board. The gypsum board comprises a body and enhanced material net layers arranged in the body uniformly. The ingredients of the body comprise, by weight, 100 parts of gypsum powder, with a fineness of 750-1000 meshes, which is a mixture of hemihydrate gypsum and dihydrate gypsum at a weight ratio of 8:1-1:2, 5-10 parts of plant fiber after cellulose degradation, with a length of 5-30 mm and a linear density of 10-20 dtex, 100-150 parts of fly ash with a fineness of 1000-1200 meshes, 0.5-1 part of coupling agents, 5-7 parts of adhesives, 1-2 parts of sodium sulfate and 40-60 parts of water. Plant fiber and enhanced material net layers are employed to enhance the gypsum board, the intensity of the gypsum board is raised effectively, therefore, the quality of the gypsum board is raised, and the production difficulty and the technology difficulty are reduced. In addition, the production cost of the gypsum board is lowered, and the enterprise benefit is raised.
Description
Technical field
The present invention relates to a kind of material of construction, particularly a kind of overall enhanced plasterboard.
Background technology
In recent years, along with the variation of buildings and the raising of environmental protection and energy saving requirement, society has also proposed the various required requirements that conform to the performance of building materials with building.Plasterboard is widely used with inorganic building material as the interior decoration of low price, good flame resistance, by market and widely recognition and acceptance of owner.For plasterboard, product strength, hold the market competitiveness that the factors such as nail ability and cost are restricting plasterboard.For this reason, filamentary material can be sneaked in gypsum product as strongthener usually, to having improved the intensity of plasterboard.
It is desirable and effective adopting the method for fiber reinforcement gypsum.But, in the Practical manufacturing operation, high through separating fine fiber volume, make a large amount of like this fibers larger with the difficulty that other starting material and who mix.In the process that is mixed, fiber is wound around in slurries, has affected to a great extent the mobility of slurries and the effect that is mixed, thereby makes the quality product heterogeneity of plasterboard, and batch quality stability of product is not high.In order to guarantee the processibility of plasterboard, can only in slurry, add a small amount of fiber.Be about 0.1-2%, be no more than at most 3%, thereby make plasterboard not reach expected effect in intensity and the improvement of holding the nail ability, affect quality, production cost and the market competitiveness of plasterboard.
Summary of the invention
For addressing the above problem, the invention discloses a kind of overall enhanced plasterboard, adopt vegetable fibre and strongthener stratum reticulare reinforced plasterboard, effectively improved the intensity of plasterboard, thereby improved the quality of plasterboard, reduce production difficulty and technology difficulty, also reduced the production cost of plasterboard simultaneously, improved the performance of enterprises.
Overall enhanced plasterboard disclosed by the invention comprises body and evenly is arranged on intrinsic strongthener stratum reticulare, the composition weight part of body is: 100 parts of terra albas, the terra alba fineness is the 750-1000 order, the semi-hydrated gypsum that terra alba is mass ratio 8:1-1:2 and dihydrate gypsum mixture; 5-10 part is through separating fine vegetable fibre, and plant fiber length is 5-30mm, and linear density is 10-20dtex; 100-150 part flyash, the fineness of flyash is the 1000-1200 order; 0.5-1 part couplant; 5-7 part cakingagent; 1-2 part sodium sulfate; 40-60 part water.Overall enhanced plasterboard disclosed by the invention, adopt vegetable fibre and strongthener stratum reticulare reinforced plasterboard, effectively improved the intensity of plasterboard, thereby improved the quality of plasterboard, adopted couplant to improve the be mixed degree of vegetable fibre in slurry, reduced the difficulty that is mixed, thereby production difficulty and technology difficulty have effectively been reduced, guarantee the quality homogeneity of cylinder batch products, also reduced the production cost of plasterboard simultaneously, improved the performance of enterprises.
A kind of improvement of overall enhanced plasterboard disclosed by the invention, vegetable fibre is for adopting liming to soak 18-36 hour and dried fiber.This improvement adopts the liming immersion treatment by vegetable fibre, oxidation-resistance and the antiseptic power of vegetable fibre have effectively been improved, improved the intensity of the fiber of plant simultaneously, and then extended the life-span of vegetable fibre in the plasterboard, and then the work-ing life of having improved gypsum board products, reduced the maintenance cost in the plasterboard use procedure.
Another improvement of overall enhanced plasterboard disclosed by the invention, couplant is silicane or titanium class or titanate ester.The couplant that this improvement adopts has strengthened vegetable fibre strongthener and other raw-material surperficial affinity effectively, thereby has effectively improved the intensity of gypsum board products, thereby has effectively improved the quality product of plasterboard.
Another improvement of overall enhanced plasterboard disclosed by the invention, couplant is vinyltrimethoxy silane or γ-glycidyl propyl trimethoxy silicane or sec.-propyl three titanic acid ester or sec.-propyl three isostearoyl base titanic acid ester or sec.-propyl three decoyl titanic acid ester.
Another of overall enhanced plasterboard disclosed by the invention improved, and cakingagent is higher alcohols or water-soluble polymer class or has the emulsion class of hydrophilic radical.The cakingagent that this improvement adopts, improved the surface bonding ability between each starting material of plasterboard, improved the adhesive effect between each material of plasterboard, effectively strengthened the bonding strength between each material of plasterboard, improved the intensity of the bonding quality of gypsum board products and plate body and held the nail ability, be convenient to the installation that is applied to of plasterboard, improved the market competitiveness of gypsum board products.
Another of overall enhanced plasterboard disclosed by the invention improved, and cakingagent is acrylic acid or the like or moisture or emulsion system vinyl-based or phenol or urea aldehydes or epoxies or starch based or melamine class.
Overall enhanced plasterboard disclosed by the invention, adopt vegetable fibre and strongthener stratum reticulare reinforced plasterboard, effectively improved the intensity of plasterboard, thereby improved the quality of plasterboard, adopted couplant to improve the be mixed degree of vegetable fibre in slurry, reduced the difficulty that is mixed, thereby production difficulty and technology difficulty have effectively been reduced, guarantee the quality homogeneity of cylinder batch products, also reduced the production cost of plasterboard simultaneously, improved the performance of enterprises.Simultaneously, adopt couplant effectively to strengthen vegetable fibre strongthener and other raw-material surperficial affinity, thereby effectively improved the intensity of gypsum board products, thereby effectively improved the quality product of plasterboard.In addition, adopt cakingagent to replace gypsum itself to want cohesive material as group, effectively improved the surface bonding ability between each starting material of plasterboard, improved the adhesive effect between each material of plasterboard, effectively strengthened the bonding strength between each material of plasterboard, improved the intensity of the bonding quality of gypsum board products and plate body and held the nail ability, be convenient to plasterboard be applied to install, improved the market competitiveness of gypsum board products.
