Abstract
The invention discloses a reinforced plasterboard and a preparation method thereof. The plasterboard comprises a plaster base material layer, and a three-dimensional reinforced fiber fabric embedded into the plaster base material layer, wherein the three-dimensional reinforced fiber fabric consists of an upper layer, an intermediate layer and a lower layer; the upper layer and the lower layer are meshed plate fiber layers; the intermediate layer refers to an 8-shaped fiber framework; and the upper and lower ends of the 8-shaped fiber framework are respectively connected with the plate fiber layers on the upper and lower layers. The three-dimensional reinforced fiber fabric serves as a product reinforcement material, and three-dimensional directional enhancement of glass fibers is structurally realized, so that the plate structure is uniform in stress. Compared with gridding cloth layout or short fiber injection and pouring and other processes, the method has the advantages that the breaking strength and compressive strength are greatly improved, and a mechanical guarantee is provided for production of large-specification/size plates. The preparation method disclosed by the invention is simple in process, and the obtained product is good in performance.
Description
Technical field
The present invention relates to building materials field, and in particular to a kind of reinforced plasterboard and preparation method thereof.
Background technology
In recent years, plasterboard with its light weight, do not fire, there is " breathing " function and enjoy the favor of user, extensively
House inner wall decoration is applied to, and existing interior wall panel strength is relatively low, sheet material is broken in transportation, installs back wall
It is easy to crack etc., make troubles to construction；Also result in huge loss simultaneously.
Although prior art is present to add fiber to strengthen plasterboard, as its fiber lays irrational asking
Topic, the mechanical strength of plasterboard still can not meet the requirement of many use occasions.
The occupation mode of the fiber of prior art is divided into three kinds of chopped fiber, fibrofelt and grid cloth.Chopped fiber is mixed into into stone
Enhanced mode is realized in cream dispensing, due to being limited by existing mixing procedure, chopped fiber is difficult to be uniformly blended into gypsum dispensing
Problem, the phenomenon for causing intensity distribution uneven is obvious.Staple fiber batt is bonded in gypsum board core surface energy suitably to change
The intensity of kind plasterboard, but this adhesive structure can not make staple fiber batt play real reinforcement function, therefore for plasterboard
Improved strength it is extremely limited.Fibrous mesh cloth strengthens, due to being limited by fibrous mesh cloth production technology, so fiber is close
The distribution consistency degree of degree and reinforcement is difficult to reach preferable degree.
Therefore, the intensity realized by plasterboard is improved again, just need to can be expected to obtain new breakthrough from new direction
Mouthful.Applicant Jing researchs draw：In actual use, the Strength Failure of plasterboard is mainly manifested in cracking and ruptures, and
Fracture is frequently experienced at cracking.The effective measures for ftractureing are avoided to be to avoid the stress concentration of plasterboard as far as possible and to the greatest extent may be used
Can uniform plasterboard intensity distribution, in said internal stress refers to that plasterboard is produced during manufacturing process or use
Stress, intensity distribution are the distributions along the length and width direction of plasterboard.
Further, current plasterboard adopts the natural gypsum mostly for main body, and the limits throughput of the natural gypsum, the place of production
Also there is significant limitation, cause the production area of plasterboard general all away from consumption area, necessarily cause the increasing of production cost
Plus, and with the increase of demand so that exhaustion is spread unchecked and is faced in natural gypsum exploitation of mineral resources, therefore, need badly and seek another kind
Material is replacing the natural gypsum.
Also known as flue gas desulfurization gypsum, sulphur gypsum or FGD gypsum, main component, as the natural gypsum, is two to desulfurated plaster
H 2 O calcium sulphate CaSO4·2H2O, content >=93%.Desulfurated plaster is titanium dioxide of the industrial enterprise of coal-fired or oil in flue gas is administered
Industry by-product gypsum obtained from after sulphur, the meaning of its processing and utilization are very great.It not only effectively promotes national environmental protection
The further development of recycling economy, and the yield of ore cream is also greatly reduced, protect resource.And desulfurated plaster
Some performances are such as：Anti- folding, resistance to compression etc., the much excellent natural gypsum, therefore be a kind of best substitute of the natural gypsum.But due to de-
Defect in the performance such as sulphur gypsum has that water content is larger, mark that thick water consumption is big, grain composition is poor, Qinshui, unit weight are big, during use
Needs are adjusted correspondingly, therefore desulfurated plaster is not also applied very well at present.Current most desulfurated plaster is also
It is, using accumulation, landfill method process, serious pollution to be caused to soil, underground water and atmospheric environment.
Therefore if plasterboard can be produced using desulfurated plaster, then the yield of the natural gypsum can be greatly decreased, be conducive to
Energy saving, Economization on land, and break a new path for the waste disposal after means of flue gas desulfurization of power plant, advantageously reduce the row of sulfur dioxide
High-volume, environmental protection.
Further, top grade club or house fitting-up do ornament materials using plank at present, high-end, air to highlight
Decorative effect, but it is the common easy moisture absorption of plank, mouldy, house ornamentation effect can be affected.In addition, plank easy firing, once there is fire, after
Really hardly imaginable, the life for giving people brings great potential safety hazard.Therefore people are more likely to use with fire-proof function
Plasterboard, but the gypsum board surface texture of existing inner wall decoration is single, it is impossible to the demand of people is met well, it is especially former
Wooden wood texture, due to its decorative effect it is noble the advantages of, be constantly subjected to the favor of people, if therefore can be in gypsum board surface mould
Intend the natural texture in log surface and then can preferably cater to consumer demand.
Further, domestic existing household building thing interior wall plasterboard, due to technical reason, the resistance to water of its surface layer,
Alkali resistance and weatherability are not enough, easy scratch, deformation and difficult cleaning and maintenance, especially easily in surface attachment Staphylococcus aureus
Harmful mushroom such as bacterium produces stink, contaminated air, affects attractive in appearance.And generally color paint coating is adopted for coloring in the wall body decoration stage
Agent, the organic matter volatilized in these coating（Formaldehyde, benzene homologues etc.）It is lasting and slow indoors, seriously threaten the body of people
Body health.Therefore how to reduce indoor VOC（VOC）Content, building Green Home has become contemporary mankind's quarter
One of slow important task is not allowed.
