Abstract
The invention discloses a fiber-modified gypsum-based composite material which is characterized by comprising the following components by mass ratio: 100 parts of beta-hemihydrate gypsum, 0.1-5 parts of high-efficiency water reducing agent, 0.05-3 parts of retarder, 0.1-5 parts of polyvinyl alcohol fiber and 40-65 parts of water. The polyvinyl alcohol fiber is short chopped fiber and has the length of 5-30mm and the good diameter of 6-70mum. The polyvinyl alcohol fiber is uniformly and disorderly distributed in the gypsum-based composite material, thus the strength and the toughness of all parts of the product can be greatly improved. The composite material disclosed by the invention has the characteristics of low cost, low power consumption, high strength and environment friendliness and can be used as the decorative material and the non-load-bearing building material.
Description
Technical field
The invention belongs to gypseous material of construction, relate to a kind of gypsum based composite of fibre modification.Particularly suitable is made the architectural decoration plastering, also can be made into building block as the non-lbearing wall material in the construction work.
Background technology
Fiber-reinforced modified gypsum product has characteristics such as high-decoration, environmental protection, fire prevention, has the good market requirement.But; What fiber reinforcement gypsum product of the prior art mainly adopted is that spun glass, terra alba, water reducer, retardant and water are that major ingredient makes; For example: CN101284722A discloses a kind of glass fiber reinforced gypsum product and method of manufacture thereof, utilizes fiberglass gridding cloth to strengthen, though strengthened the intensity and the toughness of gypsum product on the whole; But tomography partly occurred at the gypsum that does not contain glass layer, the intensity of this part gypsum and toughness are not improved.CN101851081A discloses the method for another kind of glass fiber reinforced gypsum product, and what difference was usefulness is unordered being dispersed in the product of broken glass fiber of 1-3cm, but need form a complete production network device.What this method adopted is that the α high strength gypsum is done raw material, can promote intensity, but it is general to promote effect, and technology is complicated, and cost is higher.Therefore, effectively solve each several part intensity and toughness in the gypsum product, promote the intensity of gypsum product and to combine with manufacturing cost be a problem that waits to solve significantly.
Summary of the invention
The object of the invention is intended to overcome deficiency of the prior art, and a kind of gypsum based composite with fibre modification that energy consumption is low, cost is low, environmental pressure is good, intensity is high is provided.
The gypsum based composite of fibre modification of the present invention is that β semi-hydrated gypsum, admixture and fiber etc. that market is buied are prepared the material with certain energy-conserving and environment-protective performance behind the mixing in proportion; Be a kind of good architectural decoration plastering, also can be made into building block non-lbearing wall material in construction work and well used.
Content of the present invention is: a kind of gypsum based composite of fibre modification is characterized in that: composition and quality proportioning comprise: beta-type semi-hydrated gypsum 100 mass parts, high efficiency water reducing agent 0.1～5 mass parts, retardant 0.05～3 mass parts, vinylon 0.1～5 mass parts and water 40～65 mass parts.
In the content of the present invention: said beta-type semi-hydrated gypsum can be that the plaster of paris is or/and various chemical gypsum; Be commercially available product, do not have other particular requirements.
The radioactivity of described beta-type semi-hydrated gypsum need through detect, in strict conformity with the requirement of GB6566.
In the content of the present invention: described vinylon is a chopped strand; Staple length is 5mm～30mm; Diameter is 6～70 μ m preferably, and products production enterprise has: technical fiber Manufacturing Co., Ltd etc. should be built in rich imperial special fibre ltd of Chengdu point stone basalt fibre technology ltd, Changzhou, Chongqing.
In the content of the present invention: described high efficiency water reducing agent is the water reducer good to gypsum flexibility, comprises one or both the mixture in the naphthalene water reducer (products production enterprise has: wooden building materials ltd of company only, Chongqing City three etc. is created in Anyang dicyclo auxiliary agent Ltd, Guangzhou), poly carboxylic acid series water reducer (there are Shanxi Keteng Environmental Protection Technology Co., Ltd., Nanjing in manufacturing enterprise with friendly building materials Science and Technology Ltd., Sichuan Qi Hui Science and Technology Ltd. etc.).
In the content of the present invention: said retardant is protein calcium sulphate retarder (products production enterprise has: Chongqing De Hui chemical industry Ltd, Suzhou City make the country prosperous chemical building material ltd, Shijiazhuang City snail building materials Ltd etc.).
The preparation method of the gypsum based composite that the present invention is fiber-reinforced modified is: take by weighing beta-type semi-hydrated gypsum, vinylon, high efficiency water reducing agent, retardant and water according to aforementioned proportion earlier; Phosphogypsum, vinylon, high efficiency water reducing agent and retardant are added stirrer to be stirred about 40s～60s in advance; Then the water that weighs up is added and stir 120～180s, become mould and vibratory compaction after having stirred immediately, the gypsum based composite product of tieing up enhancing modified is promptly processed in the demoulding afterwards of waiting to condense.According to real needs, can product prepn be become building block or sheet material.
Compared with prior art, the present invention has following characteristics and beneficial effect:
(1) adopt the present invention, the gypsum of use can be that the plaster of paris is or/and various chemical gypsum (wherein chemical gypsum need meet radioactivity standard); Because gypsum is the main raw material of matrix material of the present invention, as using chemical gypsum, effectively utilization not only can reduce pollution to environment, improves the ecological environment, prevents the wasting of resources, increase economic efficiency, and has good social benefit;
(2) vinylon that uses in the fiber reinforcement gypsum product provided by the invention, because employing is chopped strand, fiber is unordered being dispersed in the gypsum product evenly, can effectively avoid the fault-layer-phenomenon of gypsum product to occur, and obtains the overall enhanced effect; Compare with glass fiber reinforced gypsum material of the prior art; Though short glass fiber can have certain reinforced effects on the whole; But unsatisfactory, generally can promote intensity is about 10%～40%, and the lifting intensity of vinylon can reach 50%～120% among the present invention; Promoted intensity greatly; The chemicalstability that reaches such effect and mainly be vinylon by force, do not absorb water, antiacid alkali ability is strong, and has high elastic coefficient and tensile strength, and is better with the flexibility of gypsum in gypsum base material;
(3) vinylon that uses among the present invention because of it has lightweight and heat-insulating property, joins the apparent density and raising heat-insulating property, the heat preservation energy-saving performance of reinforced composite that can reduce material in the gypsum base material;
(4) product of the present invention all can be produced under low temperature, normal pressure, and production unit is simple, and technology is simple; Processing condition are easy to control; Starting material are easy to get, and product performance are good, realize industrial scale production easily; Have characteristics such as energy consumption is low, cost is low, environmental pressure is good, product strength height, practical.
