Abstract
The invented waterproof composite coiled material is prepared up by utilizing the good cohesiveness of nonwoven cloth and the water proof property of the modified plastics, which is made up by adding specific additives to the polypropylene, polyvinyl or polyvinyl-chloride. The modified plastics features good resistance to ageing, antioxidizing, low temp. resisting and large strength. The advantages of the water-proof coiled material are long service life, strong resistance for corrosion, extensive raw material and cheap price.
Description
The present invention relates to waterproof material, refer to a kind of nonwoven cloth and modified plastics composite of water-proof coiled material especially
Existing waterproof material is generally roofing sheet, rubber coiled material, polypropylene fibre polyethylene etc., and wherein some is as malthoid, and its intensity is low, and service life is short, and water resistance is poor; Rubber and for example in addition, its cost height, the anti-ability of wearing; Polypropylene fibre polyethylene coiled material for another example, its raw material are single be not easy to obtain and performance not ideal enough
The objective of the invention is to for solving its intensity of existing material low, service life is short, water resistance is poor, problems such as cost height and raw material are single, provide all good waterproof roll such as a kind of its service life, weatherability, corrosion resistance, water resistance, promptly a kind of nonwoven cloth and modified plastics composite of water-proof coiled material.
The used material of the present invention is that chemical fibre does not have anti-cloth and modified plastics and makes it compoundly become one wherein that the nonwoven fabric of synthetic fibre layer is can be bonding with cement (basic structure) better as the surface layer role by the heating and pressurizing method, the modified plastics layer plays waterproof action, is basic unit as watertight composition
Chemical fibre does not have anti-cloth as surface layer, and it on the one hand can be mutually bonding with the cement (being structure trunk) of basic structure, and it can be gained in strength on the other hand; As its serviceability of the modified plastics that has added other auxiliary agent, fine as anti-aging, anti-oxidant, intensity, cryogenic property etc., it can play good waterproof action as basic unit
Accompanying drawing 1, Fig. 2 represent the compound and two-sided two kinds of compound structural representations of single face, and wherein A represents surface layer, and B represents basic unit.
Basic unit of the present invention and surface layer can use multiple material. Wherein as the nothing of surface layer Spinning cloth can be polyethylene, polypropylene fibre, terylene, eyeball synthetic fibre etc.; Modified plastics as basic unit can To be modified poly ethylene, modified polyvinyl chloride, modified polypropene etc.
Surface layer of the present invention is as using nonwoven polypropylene fabric, and basic unit can use modified poly ethylene Modified polypropene makes surface layer and basic unit increase bonding force, adds anti-aging in the modified plastics Agent, antioxidant etc. improve the ageing resistance of basic unit, and increase service life; Add Activated Calcium carbonate makes its mechanical strength of basic unit obtain increasing and cost.
Surface layer of the present invention is made base with polyethylene or polypropylene when using terylene, cyanogen synthetic fibre During layer, add the PUR modification, increase the adhesive power of surface layer and basic unit, wherein processing Temperature does not reduce with surface layer intensity and basic unit reaches viscous state, makes basic unit under pressure Fully bondingly firmly be as the criterion.
In addition, its product trade mark of employed various raw materials and performance are respectively among the present invention:
1. linear low density polyethylene (LLDPE): the trade mark has 7042,7068, grand celebration production; Caking property is good, but at heating melt viscosity height during film forming, base material and surface layer adhesion strength are poor if addition is little, if addition is big, then current of electric is big during film forming
2. polyethylene from high pressure process (HDPE): the trade mark has 18D, 18G, grand celebration production; Polyethylene (PE): the trade mark has 1C7A, 1F7B, and Beijing Yanshan Petrochemical is produced, and its film extrusion is good, and intermolecular frictional property is little, but adhesive property is poor.
3. polypropylene (PP): grand celebration, the Liao Dynastyization, Shanghai produce.Itself and base material, polypropylene non-woven fabric affinity are good, and mechanical strength is good, but the flow temperature height.
4. hot melt adhesive (EVA): adhesive property is good, and hot melting temperature is low, but the cost of material height, Shanghai Chemical Plant produces.
5. antioxidant, ultraviolet (UV) resistant agent, age resister, all on sale its in domestic market can improve the service life of plastics, but costs an arm and a leg.
6. calcium carbonate, market is on sale.It can reduce cost, and increases the strong worker of machinery, and the material weather resistance descends but addition is crossed at most, and adhesive property also descends.
Because the performance of above raw material and modifier has determined have certain proportion relation can guarantee that product of the present invention has best performance between the amount of each component
Be example with the polypropylene non-woven fabric specifically, the proportioning between the each component is:
Component title content (parts by weight are represented)
LLDPE 50-80
HDPE (18D or 1C7A, 1F7B) 20-50
PP 10-50
CaCO
3 1-10
EVA 1-10
Antioxidant 0.1-1
Age resister 0.1-1
Ultraviolet (UV) resistant agent 0.1-1
Wherein, antioxidant can be N, N '-diphenyl-para-phenylene diamine etc.
In addition, age resister can be four-pentaerythritol resin and zinc oxide etc.
Once more, ultraviolet (UV) resistant agent can be a 2-dihydroxy benaophenonel etc.
After above-mentioned raw materials is extruded into plastic film, be combined into waterproof, anti-corrosion coiled material with this plastic film and nonwoven fabric hot pressing again, wherein hot pressing compound tense response parameter is:
Temperature: 100-145 ℃, pressure: 0.01～0.4MP
Nonwoven cloth and modified plastics composite of water-proof coiled material of the present invention, long service life, corrosion resistance, water resistance, weatherability all are better than existing waterproof roll, and its raw material supply abundance, and be cheap.
