Description
Technical field
The present invention relates to a kind of waterproof roll, be specially all better modified chlorinated polyethylene waterproof roll of a kind of ageing-resistant performance, physical property and processing characteristics 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 polyethylene from high pressure process 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 based on polyethylene from high pressure process or linear low density polyethylene, though every mechanical property can reach the related standards of the Ministry of Railways,, the pliability of product, planeness, resilience do not reach the requirement of construction far away.Because bridge engineering special-purpose water-proof coiled material has certain specific (special) requirements to its pliability, planeness and resilience, otherwise waterproof roll is comprehensive is bonded as one with cement based bridge floor with regard to being difficult to make.A lot of producers are therefore defective and can't normally use and be returned goods; (2) if based on haloflex (CPE), the pliability of product, planeness, resilience are all relatively good, but its mechanical performance index then differs greatly, particularly breaking strength 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 polyethylene from high pressure process and haloflex are homogeneous phase, equity, its mechanical property and pliability, planeness, resilience are then all defective.In addition, also have part producer to be material of main part with thermoplastic elastomer SBS or thermoplastic elastomer (TPE) TPE etc. at present, though various performance indications 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 ethylene-octene copolymer (POE) successful application up to now as yet at bridge engineering special-purpose water-proof coiled material.
Summary of the invention
The present invention adopts polyethylene from high pressure process to come modified chlorinated polyethylene to do the waterproof roll matrix in order to solve the special-purpose two class waterproof rolls of existing bridge engineering basically, can't satisfy the every performance indications of product fully.If adopting thermoplastic elastomer SBS or thermoplastic elastomer (TPE) 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 modified chlorinated polyethylene waterproof roll, raw material by following parts by weight is made: 85～120 parts of ethylene-octene copolymers, 10～100 parts of haloflexes, 20～180 parts of linear low density polyethylenes are filled 10～200 parts of reinforcing agents, 6～90 parts in softening plasticizing agent, 0.5～4 part of phenolic antioxidant, 0.5～4 part of heat stabilizer, 0.2～4 part of sliding agent, 0.5～2.5 part of light stabilizer; Described phenolic antioxidant is that 50% phenols primary antioxidant 1010 and 50% phenols auxiliary antioxidant 168 are made by weight ratio, and described heat stabilizer is that 50% dibasic lead phosphite and 50% lead sulfate tribasic are made by weight ratio.
Described filling reinforcing agent is calcium carbonate activated or colloid calcium carbonate; Described softening plasticizing agent is any one in dioctyl phthalate, chlorinated paraffin wax or the naphthenic oil; Described sliding agent is stearic acid or particle paraffin; Described light stabilizer is ultra-violet absorber UV327 or UV531; The chlorinty of described haloflex is 25-45%.
In the above-mentioned prescription, ethylene-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 main performance that has a rubbery is very outstanding, and the performance indications aspect a lot of have surpassed common elastic body.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 processability again as the physical crosslinking point; (2) relative molecular mass narrowly distributing, good with compatible polyolefin, have preferable flowability; (3) do not have the two keys of insatiable hunger, excellent weather resistance and hard is in other elastic body; (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 inserts, also can improve the weld mark strength of goods simultaneously.The particularity of POE molecular structure has been given its excellent mechanical property, rheological property and anti-ultraviolet property.Ethylene-octene copolymer (POE) is to combine rubber and a kind of material of plastics advantage, its plastics at high temperature can flow mutually, then play the effect of physical crosslinking point at normal temperatures, this physical crosslinking is that heat is reversible, therefore it both can use the processing method moulding of thermoplastic, it has the elasticity of rubber again in wider temperature range, the present invention first with ethylene-octene copolymer (POE) successful application on bridge engineering special-purpose water-proof coiled material.
Haloflex (CPE) is the chloride polyolefin of being made through chlorination by polyethylene, it is the armorphous chloride saturated elastic body of a kind of line style, difference according to chlorinty can be divided into soft plastic (chlorinty is less than 25%), elastic body (chlorinty 25%～45%) and rigid plastics (chlorinty 45%～70%), because the introducing of chlorine atom, make two keys in the original structure and cladodification place etc. cause that easily the factor of chemical degradation and thermal degradation disappears, thereby make it have good against weather, flame resistance and resistance to low temperature, the present invention quotes haloflex in design, except above-mentioned factor, also has the adhesion problem that key factor is exactly N class waterproof roll and cement matrix cementing agent, because haloflex is a kind of macromolecular material that has polarity, superior with the adhesive property of common bond, and POE, the adhesive property of 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% haloflex with chlorinty.
Because above-mentioned two type of elastomeric bodies are added certain softening agent, its hot strength is had a greatly reduced quality do not reach the designing requirement of product far away, even add suitable reinforcing filler, though intensity has some improvement, but a certain distance is still arranged with the designing requirement of waterproof roll, and elongation rate also can descend by straight line, in order both to reach the designing requirement of product performance index, consider the formulation cost of product again, the applicant is through test of many times and summary of experience, on prescription, added linear low density polyethylene (LLDPE) as the plastics phase, lose under the little situation at elongation rate through test, its hot strength is greatly improved, fracture tensile strength 〉=the 18MPa of N class waterproof roll, elongation at break 〉=900%, the fracture tensile strength 〉=200N/cm/1.5mm of the two-sided compound nonwoven cloth waterproof coiled material of L class, elongation at break 〉=800%, all other indexs are all above the related standards of the national standard and the Ministry of Railways, and the component design cost of product also significantly descends.
For the further prescription of optimizing this product, the index of enhancing product performance, the present invention has also added following raw material, and the effect of filling reinforcing agent is the intensity of increase product partly and the formulation cost of reduction product; The main effect of softening plasticizing agent is the flexibility that increases product; The main effect of phenolic antioxidant is to improve product heat resistanceheat resistant, ageing resistace in use, prolongs the application life of waterproof roll; The effect of heat stabilizer mainly is the thermal decomposition that prevents or stop haloflex to cause owing to high temperature in process; The main effect of sliding agent is to prevent high polymer in the process of converted products, and the high temperature that excessively produces owing to friction decomposes high polymer; The main effect of light stabilizer is to prevent owing to the width of cloth of light is penetrated the high polymer decomposition that causes.
