Abstract
A water-proof coiled material for water-proof engineerings such as railway, highway, culvert and dam contains such components (wt. portions) as ethylene-vinyl acetate resin (30-80), low-density linear polyethylene (10-60) and charge (6-10) and is made up through mixing, extruding, calendering, thermally treating and cutting. Its advantages include low cost, long service life, excellent ageing and low temp resistances, service temp at -35-+120 deg.C, more than 600% of elongation coefficient and tension strength and high anti-leakage nature.
Description
The present invention relates to a kind of waterproof roll that waterproofing works such as subway road, culvert, Ba Chi are used that is used for.
The present invention in the past, the main raw material(s) that is used to make waterproof roll has modifying asphalt, modified rubber and single synthetic resins, as polyvinyl chloride etc., 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.
It is good to the purpose of this invention is to provide a kind of good springiness, tensile strength height, lower temperature resistance, ageing resistance, the dawn storing is simple, a kind of waterproof roll of easy construction, this waterproof roll should be able to also can be realized firm waterproof action under complex environments such as construction, vibration, distortion.
The object of the present invention is achieved like this:
Prepare according to raw-material component and parts by weight, at first take by weighing ethene-vinyl acetate between to for plastic 30-80, linear low density polyethylene resin 10-60, Synergist S-421 95 6-10.
In the Synergist S-421 95, contain modifying asphalt, anti-aging agent, softening agent, forming its weight part overall control is 6-10; Can also add thermo-stabilizer.
In the Synergist S-421 95, the weight part total amount that adds an amount of required pigment and other component of Synergist S-421 95 as required is 6-10.
Above-mentioned raw materials is dropped in the mixing tank simultaneously, under normal temperature batch mixing 15-25 minute, through two sections forcing machines, extrude required amount of resin, roll into desired thickness through rolling press again, after the constant temperature thermal treatment, cut required width, length, curling packing forms.
The present invention is a kind of novel waterproof roll, adopts ethene-vinyl acetate resin material, and coiled material has higher lower temperature resistance, outstanding ageing resistance, elasticity.Processibility, dyeability are preferably arranged simultaneously, the fusion good with Synergist S-421 95.Adopt linear low density polyethylene, make coiled material that superior mechanical strength be arranged, environmental stress crack resistance, heat-resisting, cold-resistant.Add Synergist S-421 95, the physical and mechanical properties of coiled material is improved, particularly tensile strength increases, the water leakage raising, and safe in utilization, cost is low, and the dawn storing is simple, easy construction.
The rerum natura result specification size of coiled material of the present invention is as follows:
Tensile strength: be not less than 15-20Mpa;
Extension at break degree (%): be not less than 600;
Low-temperature bending :-35 ℃ of flawlesses;
Permeability resistance: do not have infiltration;
Binding property under the shearing condition (N/mm): be not less than 5
Coiled material thickness, width mm:0.65-2.0,2000-2100.
Provide specific embodiment below:
