Abstract
The present invention relates to water-repellent coiled material and a producing method thereof. The surface layer (1) and the bottom layer (2) of the coiled material are non-woven fabric, and the middle layer (3) of the coiled material is powdery waterproof material; the water-repellent coiled material is manufactured by means of needling processes, and the surface layer (1) and the bottom layer (2) are tightly connected by needling fiber; the powdery waterproof material in the middle layer (3) is thoroughly stiffened by the needling fiber. The present invention has the advantages of simple production process, reliable seepage prevention, water prevention and damp prevention, fine durability, long service life, low price, convenient construction, etc. The water-repellent coiled material can be widely used for occasions of engineering of seepage prevention, water prevention and damp prevention for buildings, and the water-repellent coiled material has great implementation value, social benefit and economic benefit.
Description
The present invention relates to a kind of water repellent coiled material and production method thereof, the water repellent coiled material of producing with this method is applicable to the occasion of building antiseepage waterproof and moistureproof engineering as waterproof material.
Before the present invention made, the building water-proof material mainly contained four classes: 1. waterproofing agent is a main component with the alumite plumping agent mainly, mixes and makes waterproof mortar and water-proof concrete; 2. coating mainly contains asphaltic base, rubber-based and resin-based water-repellent paint; 3. coiled material mainly contains asphaltic base, rubber-based and resin-based waterproof roll, and what generally use is the asphaltic base waterproof roll; 4. pulverulent material, promptly hydrophobe mainly contains fatty acid calcium type and organosilicon type; Especially coiled material and hydrophobe, in the coiled material, as asphalt felt is two sides with pitch dip-coating body paper, form at this two sides spreading talcum powder or mica sheet then, be mainly used in roof waterproof engineering and other antiseepage, the occasion of moistureproof engineering, this coiled material percentage elongation is low, poor durability, service life is short, and construction is complicated, and for example EPDM rubber waterproof rolling material, based on ethylene propylene diene rubber, mix an amount of vulcanizing agent, promoter, softening agent and stuffing are through banburying, extrusion molding, sulfuration and branch coil packing form, and are mainly used in the occasion of roof waterproof engineering, this coiled material excellent performance, good endurance, long service life, but cost an arm and a leg; Hydrophobe has two classes, one class is the organosilyl hydrophobe of core outsourcing with flyash, another kind of is the hydrophobe of core outsourcing fatty acid calcium with calcium hydroxide or calcium carbonate, be mainly used in the occasion of roof waterproof engineering and other antiseepage, moistureproof engineering, such pulverulent material good endurance, long service life, low price, but pulverulent material construction trouble.
Task of the present invention is the shortcoming that overcomes prior art, provides that a kind of production technology is simple, the water repellent coiled material and the production method thereof of waterproof and dampproof reliable, the good endurance of antiseepage, low price, easy construction.
Water repellent coiled material, its main material is a chemical fibre, glass, mineral wool, the bondedfibre fabric of rock wool and plant cotton and powdery waterproof material hydrophobe, hydrophobe has two classes, one class is the organosilyl hydrophobe of core outsourcing with flyash, another kind of is the hydrophobe of core outsourcing fatty acid calcium with calcium hydroxide or calcium carbonate, this water repellent coiled material is by surface layer (1), bottom (2), middle level (3) constitutes, surface layer (1) and bottom (2) are chemical fibre, glass, mineral wool, the bondedfibre fabric of rock wool and plant cotton, the bondedfibre fabric mass area ratio of surface layer (1) and bottom (2) be 50-700 gram/square metre, the middle level (3) that is provided with between surface layer (1) and the bottom (2) be the powdery waterproof material hydrophobe, the hydrophobe mass area ratio of this middle level (3) be 1000-10000 restrain/square metre.Be tiled in the powdery waterproof material hydrophobe on the bondedfibre fabric of bottom (2) through the batcher even feeding, the powdery waterproof material hydrophobe is middle level (3), bondedfibre fabric with surface layer (1) is tiled on the middle level (3) again, by needing machine surface layer (1), middle level (3), bottom (2) are carried out composite acupuncture, composite acupuncture density is 10-1000 pin/square centimeter, surface layer (1) and bottom (2) are closely linked by needling fiber, middle level (3) waterproof material hydrophobe is by the abundant reinforcement of needling fiber, repair through periphery again, constitute the good water repellent coiled material of globality.
Water repellent coiled material of the present invention and production method thereof, compared with prior art, antiseepage is waterproof and dampproof reliable, good endurance, long service life, low price overlap easy to be reliably, and easy construction has broad application prospects and the significant social economic benefit.
Fig. 1 is the structural representation of water repellent coiled material.
1-surface layer wherein, the 2-bottom, the 3-middle level, surface layer (1) and bottom (2) they are the bondedfibre fabric of chemical fibre, glass, mineral wool, rock wool and plant cotton, middle level (3) are the powdery waterproof material hydrophobe by the abundant reinforcement of needling fiber.
As shown in Figure 1, water repellent coiled material of the present invention and production method thereof, embodiment is: the water repellent coiled material main material is polyster fibre bondedfibre fabric and powdery waterproof material hydrophobe, hydrophobe is for being the hydrophobe of core outsourcing calcium stearate with the precipitated calcium carbonate, this water repellent coiled material is by surface layer (1), bottom (2), middle level (3) constitutes, surface layer (1) and bottom (2) are the polyster fibre bondedfibre fabric, the polyster fibre bondedfibre fabric mass area ratio of surface layer (1) and bottom (2) be 250 the gram/square metre, the middle level (3) that is provided with between surface layer (1) and the bottom (2) is for being the hydrophobe of core outsourcing calcium stearate with the precipitated calcium carbonate, the hydrophobe mass area ratio in this middle level (3) be 5000 the gram/square metre, be tiled in this powdery waterproof material hydrophobe on the polyster fibre bondedfibre fabric of bottom (2) through the batcher even feeding, this hydrophobe is middle level (3), polyster fibre bondedfibre fabric with surface layer (1) is tiled on the middle level (3) again, by needing machine with surface layer (1), middle level (3), bottom (2) carries out composite acupuncture, composite acupuncture density is 100 pin/square centimeters, surface layer (1) and bottom (2) are closely linked by the acupuncture polyster fibre, middle level (3) waterproof material hydrophobe is by the abundant reinforcement of acupuncture polyster fibre, handle through periphery, constitute whole good water repellent coiled material, can be widely used in roofing, the occasion of building antiseepage waterproof such as ground and moistureproof engineering, it is simple to have production technology, antiseepage is waterproof and dampproof reliable, good endurance, long service life, low price, advantages such as easy construction have bigger implementary value.
