Description
Technical field
The present invention relates to waterproof roll technical field, specifically the special-purpose L type of a kind of rubber plastic blend high-speed rail bridge waterproof roll and preparation method thereof.
Background technology
Bridge construction Special waterproof coiled material that at present each manufacturer produces, adopts high-pressure polyethylene to come modified chlorinated polyethylene to do waterproof roll matrix substantially.Although the formula of each manufacturer, technique difference, but all exist very large defect: (1) is if take high-pressure polyethylene as main body, although every mechanical property can reach the related standards of the Ministry of Railways, but the pliability of product, planeness, rebound resilience do not reach the requirement of construction far away, because bridge construction Special waterproof coiled material has certain particular requirement to its pliability, planeness and rebound resilience, otherwise with regard to being difficult to make, waterproof roll is comprehensive is bonded as one with cement based bridge floor, and a lot of producers cannot normally be used and be returned goods because this is defective; (2) if take chlorinatedpolyethylene (CPE), be main body, the pliability of product, planeness, rebound resilience are all relatively good, but its mechanical performance index differs greatly, particularly breaking tenacity can only be in 90N/cm/1.5mm left and right (related standards of the Ministry of Railways is >=160N/cm/1.5mm); (3) if this bi-material is homogeneous phase, equity, its mechanical property and pliability, planeness, rebound resilience are all defective; (4) if be material of main part with thermoplastic elastomer TPE etc., although various performance index can reach requirement, formulation cost is too high, can not adapt to the running of present market economy.Applicant finds to adopt thermoplastic elastomer to chlorinatedpolyethylene and linear low density polyethylene modification through research, not only property indices is superior, the more important thing is that formulation cost relatively uses other thermoplastic elastomer or the rubber at least will low 1/3rd left and right, if so just can win more wide market, and up to now, also there is not yet divinyl-styrene block copolymer (SBS) successful application at the report of bridge construction Special waterproof coiled material.
Summary of the invention
The object of the invention is in order to solve above-mentioned problems of the prior art, and all better novel bridge engineering Special waterproof coiled materials of a kind of ageing-resistant performance, physicals and processing characteristics, the specifically special-purpose L type of a kind of rubber plastic blend high-speed rail bridge waterproof roll and preparation method thereof be provided.The present invention is that to take thermoplastic elastomer divinyl-benzene second block alkene copolymer (SBS) and chlorinatedpolyethylene (CPE) be rubber phase, linear low density polyethylene (LLDPE) is plastics phase, add appropriate softening agent, fill toughener and various subsidiary material, the bridge Special waterproof coiled material of the L type that is matrix through blending extrusion.
The present invention is achieved by the following technical solutions:
The special-purpose L type of a high-speed rail bridge waterproof roll, is made by the raw material of following parts by weight: 100 parts of butadiene-styrene block copolymers, chlorinatedpolyethylene 20-60 part, linear low density polyethylene 20-180 part, filling toughener 30-200 part, softening softening agent 60-150 part, phenolic antioxidant 0.5-4 part, thermo-stabilizer 0.5-4 part, lubricant 0.2-4 part, photostabilizer 0.5-2.5 part.
Waterproof roll of the present invention is butadiene-styrene block copolymer for Bian (SBS), these two kinds of thermoplastic elastomers (elastomerics) of chlorinatedpolyethylene (CPE) and linear low density polyethylene (LLDPE) blend, and be aided with suitable filling enhancing modified and other subsidiary material, obtain the performance of product and the novel bridge Special waterproof coiled material that cost is taken into account.
The English name of butadiene-styrene block copolymer of the present invention: thermoplastic elastomer SBS, SBS is the segmented copolymer of vinylbenzene and divinyl, claims again thermoplasticity butadiene-styrene block copolymer or thermoplastic styrene butadiene rubber.Different according to synthetic method, SBS has linear structure and hub-and-spoke configuration, and SBS is white or micro-yellow Round Porous bar or disc particle, relative density 0.92～0.95, SBS has good tensile strength, elasticity and electrical property, and tension set is little, it is good to subdue with rebound resilience, and surface friction is large.Because main chain contains two keys, cause SBS ageing resistance poor, under the oxidizing condition of high temperature air, butadiene block can be cross-linked, thereby the hardness of making and viscosity increase (so in formula, adding the auxiliary materials such as antioxidant).After SBS is heated, material can flow, easily machine-shaping.After cool to room temperature, polystyrene segment is gathered into vitreous state microcell, polybutadiene segments has been played to the effect of physical crosslinking point, thereby makes bill of material reveal the characteristic of rubber, is therefore referred to as " thermoplastic elastomer ".SBS has two phase structure: polyhutadiene phase---external phase, polystyrene phase---disperse phase.
Divinyl-styrene block copolymer (thermoplastic elastomer) is a kind of material that combines rubber and plastics advantage, its plastics at high temperature can flow mutually, play at normal temperatures the effect of physical crosslinking point, this physical crosslinking is that heat is reversible, therefore it both can use the working method moulding of thermoplastics, and it has again the elasticity of rubber in wide temperature range.
Chlorinatedpolyethylene is the chloride polyolefine of being made through chlorination by polyethylene, be called for short CPE, it is the armorphous chloride saturated elastomerics of a kind of line style, according to the difference of chlorinity, can be divided into soft plastic (chlorinity is less than 25%), elastomerics (chlorinity 25%～45%) and rigid plastics (chlorinity 45%～70%), introducing due to chlorine atom, make two keys in primary structure and cladodification place etc. easily cause that the factor of chemical degradation and thermal destruction disappears, thereby make it there is good weathering resistance, flame resistivity and resistance to low temperature.The present invention quotes a small amount of chlorinatedpolyethylene in design, except above-mentioned factor, also have an important factor be exactly because of chlorinatedpolyethylene be a kind of superior with the macromolecular material of polarity and the adhesive property of common bond, and the adhesive property of butadiene-styrene block copolymer (SBS), linear low density polyethylene (LLDPE) and common bond is just difficult to bonding, generally select chlorinity to be advisable at the chlorinatedpolyethylene of 35% left and right.
Because this elastomerics of two types (SBS and CPE) is added certain softening softening agent, its tensile strength is had a greatly reduced quality, do not reach the design requirements of product far away, even if add suitable filling toughener, although having some improvement, intensity still has a certain distance with the design requirements of product, and elongation also can decline by straight line, in order to reach the design requirements of product performance index, consider again the formulation cost of product, the linear low density polyethylene (the waste and old pellet of the good high-pressure polyethylene of Performance Ratio also can replace linear low density polyethylene by a part) that we have used some amount in proportioning loses little in the situation that at elongation through test, its tensile strength is greatly improved, fracture tensile strength >=the 200N/cm/1.5mm of waterproof roll of the present invention, tensile yield >=800%, all other indexs are all over the related standards of national standard and the Ministry of Railways, and the component design cost of product also significantly declines.
Further, described filling toughener is 400 object activated Calcium carbonates or colloid calcium carbonate, and its Main Function is the formulation cost that increases the intensity of product and reduce product; Described softening softening agent is naphthenic oil, and its Main Function is the flexibility that increases product; The secondary irgasfos 168 of the phenols primary antioxidant 1010 that described phenolic antioxidant is 1:1 by weight ratio and phenols is made, and its Main Function is thermo oxidative aging; Dibasic lead phosphite and lead sulfate tribasic that described thermo-stabilizer is 1:1 by weight ratio are made, and its effect is mainly the thermolysis that prevents or stop chlorinatedpolyethylene to cause due to high temperature in the course of processing; Described lubricant is two kinds of a kind of or arbitrary proportion in stearic acid, whiteruss, and its Main Function is to prevent that superpolymer is in the process of converted products, and the high temperature excessively producing due to friction makes superpolymer decomposition; Described photostabilizer is ultraviolet absorbent UV-531, and its Main Function is to prevent because the width of light is penetrated the superpolymer decomposition causing.
