The invention discloses the puncture resistance water-proof sheet and preparing method, comprising 75-85 parts low density polyethylene, 5-10 parts thermoplastic elastomer SBS, 2-8 parts color masterbatch, 2-5 parts auxiliary agent and 5-10 parts filling agent. The invention uses extrusion forming method. The sheet has advantages of good water-proof property, antiseep, weatherability, high hot strength, low linear expansion, big frictional factor, large temperature range, long life and low cost. The invention can be used in underground, road, harbour, and culverts.
Description
Technical field
The invention belongs to the water-proof material preparation field, relate to a kind of enhancing piercing resistant flashing (being called for short LECB) and preparation method thereof.
Background technology
The main raw material(s) that is used to make waterproof sheet has modified rubber and single synthetic resins, as polyolefin resines such as polyvinyl chloride, polyethylene, waterproof roll with above material preparation, its elasticity is little, elongation is low, tensile strength is low, weather resistance, lower temperature resistance are poor, has caused the water leakage extreme difference of coiled material.And leakage of building is the Universal Problems on puzzlement building circle, and relevant departments such as the portion of nation-building in recent years, each province and city capital construction commission have put into effect various rules, regulation.Each R﹠D institution has also developed many waterproof materials, but can not stop leakage problems fully all the time.Existing water-proof material adopts modifying asphalt and thermoplastic elastomer SBS's blend to make waterproof roll mostly, owing to rerum natura, structural distortion, the construction of water-proof material and protect reasons such as improper, still can not prevent the seepage of buildings.
Summary of the invention
The shortcoming that the objective of the invention is to overcome prior art provides a kind of piercing resistant flashing and preparation method thereof with not enough.
Technical scheme of the present invention is as follows:
Enhancing piercing resistant flashing of the present invention is made up of following materials based on weight:
75～85 parts of linear low density polyethylenes
5～10 parts of thermoplastic elastomer SBSs
2～8 parts of colour batches
1～5 part of auxiliary agent
5～10 parts of weighting agents
Wherein said SBS is the styrene-butadiene-styrene terpolymer, and its proportion of composing is that S/B is 30/70～50/50 (weight).
Auxiliary agent of the present invention comprises photostabilizer, oxidation inhibitor or lubricant or the like.
Described photostabilizer comprises UV light absorber UV531;
Described oxidation inhibitor comprises antioxidant 1010;
Described lubricant comprises stearic acid, Zinic stearas;
Described weighting agent is: lightweight or heavy treated carbonates.
Described colorant comprises that shades of colour is as black, red, yellow or green or the like.
Colour batch of the present invention contains linear low density polyethylene, white oil and colorant, and its composition and proportioning are as follows: 15～25 parts in 35～65 parts of linear low density polyethylenes, 25～65 parts of white oils and colorant.
The preparation method of enhancing piercing resistant flashing of the present invention (being called for short LECB), be to put above-mentioned all raw materials into high-speed mixer by prescription requirement metering to mix, the material that mixes is added in the forcing machine hopper, enter in the extruder barrel, rack-style die lip of heating and become the fused sheet, enter tri-roll press machine again and roll into certain thickness thin slice,, draw through tractor through cutting off into the sheet of certain width, be cut into the volume of certain-length, make the enhancing piercing resistant flashing.
The inventor has scrutinized present construction technology, adopt modifying asphalt and thermoplastic elastic body styrene-butadiene-styrene terpolymer (SBS) blend to make waterproof roll, exist following shortcoming: 1, waterproof roll is made in modifying asphalt and thermoplastic elastomer SBS's blend, tensile strength is low, elongation is little, poor performance.Break easily when 2, waterproof roll is made in laying modifying asphalt and thermoplastic elastomer SBS's blend.3, poor performance such as the waterproof of this waterproof roll, antiseep, weathering resistance.4, scurry water behind the laying water-proof coiled material easily, scurry the water source that is difficult for finding to scurry water behind the water.
In order to solve this long-term indeterminable difficult problem, the present invention makes waterproof roll to the modifying asphalt of present use and thermoplastic elastomer SBS's blend and analyzes, and especially the forming method of choices of raw materials, Formula Design and enhancing piercing resistant flashing and moulding process are soundd out and studied.Selecting linear low density polyethylene, thermoplastic elastomer SBS, auxiliary agent and colour batch etc. for use is raw material, roll into certain thickness thin slice through extruding with tri-roll press machine, through cutting off into the sheet of certain width, draw the volume that is cut into certain-length through tractor, just made the LECB waterproof sheet.
The present invention has carried out a series of experiments and has comprised in the selecting for use of material, Formula Design: (1), the fixing consumption of colour batch, auxiliary agent and weighting agent, and select for use HDPE, LDPE, EVA and LLDPE raw material to carry out extrusion calendaring experiment, test performance data respectively.(2), fixedly raw material, colour batch and weighting agent, the kind and the consumption that change auxiliary agent carry out extrusion calendaring experiment, test performance data.(3), in order to reduce cost, the present invention adopts the kind and the consumption that change weighting agent to carry out extrusion calendaring experiment, test performance data.Obtain the prescription of cost performance the best.
The present invention strengthens the characteristics of piercing resistant flashing (be called for short LECB): have good puncture resistance, waterproof, antiseep, weathering resistance, high tensile, low linear expansion, frictional coefficient is big, distortion adaptability is strong, thermal adaptation wide ranges, easy to use, many good mixed economies, technical performance index such as the life-span long, easily construction and cost be low.
