Abstract
The invention relates to a waterproof material, in particular to an acid rain resistant CPE waterproof coiled material. The material solves the waterproof problem of buildings in an acid rain environment. The material is prepared from raw materials with the following proportions by weight: 50-70 percent of chlorinated polyethylene, 15-25 percent of light calcium carbonate, 7-12 percent of silicondioxide, 2-6 percent of talcum powder and 4-7 percent of carbon black. The relative change rate of tensile strength is -5 percent in vertical direction and -4 percent in horizontal direction and the relative change rate of elongation at break is +2 percent in vertical direction and +2 percent in horizontal direction. Compared with domestic similar products, the coiled material has the advantages of high strength, corrosion resistance, acid-base resistance, high and low temperature resistance, environmental protection, no pollution, convenience for construction, wide application range and the like.
Description
Technical field
The present invention relates to a kind of waterproofing materials, be specially a kind of acid rain resistant CPE waterproof coiled material.
Background technology
Waterproof is one of critical function of all kinds of buildings.So in building operations, will take corresponding waterproof technique to guarantee the water resistance of building.So the quality of waterproofing materials quality is directly determining the waterproof effect of building.The problem of China's building trade waterproof existence at present is many, and the leakage of buildings problem is quite serious.Especially recently because industrial development is rapid, and atmosphere pollution is serious, certain areas acid rain occurs more and more frequent.Acid rain has caused serious corrosion to facilities such as building, bridges, and traditional waterproof measure is difficult to address this is that fully.The domestic leading material that is directly used in waterproofing course more than 80% is a waterproof roll at present, and general waterproof roll all is asphalt felt, asphalt modification coiled material, macromolecule coiled material etc.Though these materials can improve the water resistance of building, for the area that acid rain occurs, this material still is corroded very soon, can not finish water-proof impervious task well.
Summary of the invention
The present invention provides a kind of acid rain resistant CPE waterproof coiled material for the waterproof problem that solves building under the acid rain environment.
The present invention is realized by following technical scheme, and a kind of acid rain resistant CPE waterproof coiled material is to be made by the raw material of following weight ratio example: haloflex 50-70%, precipitated calcium carbonate 15-25%, silica 7-12%, French chalk 2-6%, carbon black 4-7%.
Above material gets final product according to the explained hereafter of plastics or rubber, mediates through too high stirring, and plasticate and extrude, the calendering press polish, cooling, volume series of steps such as drives and can finish.
The present invention adopts the high-efficiency taper prepared in twin-screw extruder to become in its anti-change-blood corrosivity of moral waterproof roll acid solution to handle the relative change rate to dwindle greatly.Tensile strength relative change rate vertically-5%, laterally-4%, the elongation at break relative change rate vertically+2%, laterally+2%..With domestic like product relatively, have the intensity height, corrosion-resistant, acid and alkali-resistance, high-low temperature resistant, environment friendly and pollution-free, easy construction, advantage such as the scope of application is wide.The relative change rate all dwindles in 8% because of its resistance to chemical attack acid treatment, and product improves application life greatly, can effectively solve China Central China, south China, and southwest, a large amount of acid rain phenomenons that occur in East China and ground such as coastal are to the corrosion harmfulness of building.Simultaneously, this product also has the heat reflection function, can play the heat-insulation and heat-preservation effect.For decoration of exterior wall, not only play impermeabilisation, protection against the tide, the effect of mildew-resistant can also be played the effect of beautifying the environment.
The specific embodiment
Embodiment 1, and a kind of acid rain resistant CPE waterproof coiled material is to be made by the raw material of following weight ratio example: haloflex 50%, precipitated calcium carbonate 25%, silica 7%, French chalk 6%, carbon black 4%.
Produce and adopt the high-efficiency taper double screw extruder, introduce microcomputer control system, can science accurately control technological temperature, the roller rotating speed makes the presentation quality of product reach optimum efficiency, has improved product physical and mechanical property index simultaneously greatly.Overcome the coiled material that device fabrication in the past goes out problems such as bubble, scar, cavity have been arranged.
Embodiment 2, and a kind of acid rain resistant CPE waterproof coiled material is to be made by the raw material of following weight ratio example: haloflex 70%, precipitated calcium carbonate 15%, silica 1 2%, French chalk 2%, carbon black 7%.
Embodiment 3, and a kind of acid rain resistant CPE waterproof coiled material is to be made by the raw material of following weight ratio example: haloflex 60%, precipitated calcium carbonate 20%, silica 1 0%, French chalk 5%, carbon black 5%.
