The waterproof coiled material not only retains the special softness, elongation and resilience of the rubber, but also retains higher tensile strength at break of LLDPE, has good softness, straightness and flatness, has performance index in excess of the national standard and related standards of the Ministry of Railways, has excellent aging resistance, physical performance and processability and has low production cost.
Description
Technical field
The present invention relates to a kind of waterproof product that contains linear low density polyethylene, be specially a kind of waterproof roll that contains linear low density polyethylene and preparation method thereof.
Background technology
At present each manufacturer special-purpose N class (no composite bed coiled material) of bridge, L class (two-sided compound nonwoven cloth) type waterproof roll of producing adopts high-pressure polyethylene or linear low density polyethylene to come modified chlorinated polyethylene to do the waterproof roll matrix basically.Though the prescription of each manufacturer, technology difference all exist very big defective; (1) if be the main body with high-pressure polyethylene or linear low density polyethylene, though each item mechanical property can reach the related standards of the Ministry of Railways,, the pliability of product, planeness, rebound resilience do not reach the requirement of construction far away.Because bridge construction special-purpose water-proof coiled material has certain particular requirement to its pliability, planeness and rebound resilience, otherwise just be difficult to make the comprehensive cement based bonding of waterproof roll to be one with bridge floor.A lot of producers are therefore defective and can't normally use and returned goods; (2) if be the main body with chlorinatedpolyethylene (CPE); The pliability of product, planeness, rebound resilience are all relatively good; But its mechanical performance index then differs greatly, particularly breaking tenacity can only be about 90N/cm/1.5mm (related standards of the Ministry of Railways is >=160N/cm/1.5mm-1.8mm); (3) if these two kinds of materials of high-pressure polyethylene and chlorinatedpolyethylene are homogeneous phase, equity, its mechanical property and pliability, planeness, rebound resilience are then all defective.In addition, also have part producer to use TPR SBS or thermoplastic elastomer TPE etc. to be material of main part at present, though various performance index can both reach requirement, formulation cost is too high, can not adapt to the running of present market economy.Do not see the report of ethene-octene copolymer (POE) successful application up to now as yet at bridge construction special-purpose water-proof coiled material.
Summary of the invention
The present invention adopts high-pressure polyethylene to come modified chlorinated polyethylene to do the waterproof roll matrix in order to solve the special-purpose two types of waterproof rolls of existing bridge construction basically, can't satisfy product each item performance index fully.If adopting TPR SBS or thermoplastic elastomer TPE is material of main part, cause the too high problem of formulation cost, a kind of modified chlorinated polyethylene waterproof roll and preparation method thereof is provided.
The present invention adopts following technical scheme to realize: a kind of waterproof product that contains linear low density polyethylene, process by the raw material of following parts by weight: 110～130 parts of ethene-octene copolymers, 70～90 parts of chlorinatedpolyethylenees; 140～180 parts of linear low density polyethylenes are filled 70～190 parts of tougheners, 65～80 parts in softening softening agent; 2～4 parts of phenolic antioxidants; 2～4 parts of thermo-stabilizers, 2～4 parts of lubricants, 1.5～2.5 parts of photostabilizers; Described phenolic antioxidant is that 50% phenols primary antioxidant 1010 and 50% phenols auxiliary antioxidant 168 are processed by weight ratio, and described thermo-stabilizer is that 50% dibasic lead phosphite and 50% lead sulfate tribasic are processed by weight ratio.
Described filling toughener is treated carbonates or colloid lime carbonate; Described softening softening agent is any one in DOP, clorafin, imitative hydrogen oil or the NO; Described lubricant is Triple Pressed Stearic Acid or particle paraffin; Described photostabilizer is UV light absorber UV327 or UV531; Octene content is 30-50wt% in said ethene-octene copolymer, and cl content is 25-45wt% in the chlorinatedpolyethylene.。
In the above-mentioned prescription; Ethene-octene copolymer (POE) is that U.S. DOW chemical company is the thermoplastic elastomer of narrow relative molecular mass of having of catalyzer and short-chain branch distribution uniformly with the metallocene; This elastomeric salient features that has a rubbery is very outstanding, and the performance index aspect a lot of have surpassed common elastomerics.Why POE has excellent performance, can realize extruding at a high speed relevant with following characteristics: flexible chain coiled structure of (1) octene and crystalline ethylene chain make it have excellent toughness and have good processibility again as the physical crosslinking point; (2) relative molecular mass narrowly distributing, good with compatible polyolefin property, have preferable flowability; (3) do not have unsaturated double-bond, excellent weather resistance and hard is in other elastomerics; (4) stronger shearing sensibility and melt strength can be realized extruding at a high speed, improves output; (5) good flowability can be improved the dispersion effect of stopping composition, also can improve the weld mark strength of goods simultaneously.The singularity of POE molecular structure has been given its excellent mechanical property, rheological property and anti-ultraviolet property.Ethene-octene copolymer (POE) is to have combined rubber and a kind of material of plastics advantage; Its plastics at high temperature are can mobile mutually; Then play the effect of physical crosslinking point at normal temperatures, this physical crosslinking is hot reversible, so it both can use the working method moulding of thermoplastics; It has the elasticity of rubber again in awide temperature range, the present invention first with ethene-octene copolymer (POE) successful application on bridge construction special-purpose water-proof coiled material.
Chlorinatedpolyethylene (CPE) is the chloride polyolefine of being processed through chlorination by Vilaterm; It is the armorphous chloride saturated elastomerics of a kind of line style; Difference according to chlorinity can be divided into soft plastic (chlorinity is less than 25%), elastomerics (chlorinity 25%～45%) and rigid plastics (chlorinity 45%～70%), because the introducing of chlorine atom makes primary structure be prone to cause that the factor of chemical degradation and thermal destruction disappears; Thereby make it have good weathering resistance, flame resistivity and resistance to low temperature; The present invention quotes chlorinatedpolyethylene in design, except above-mentioned factor, also have the adhesion problem that important factor is exactly N class waterproof roll and cement matrix sticker; Because chlorinatedpolyethylene is a kind of polar macromolecular material that has; Superior with the adhesive property of common bond, and the adhesive property of POE, LLDPE and common bond is poor, is difficult to bonding.Prove that through test of many times the present invention preferably is advisable at 35% chlorinatedpolyethylene with chlorinity.
