Description
Technical field
The present invention relates to waterproof building material field, specifically a kind of modified asphalt waterproof coiled material.
Background technology
From the seventies, World Developed Countries starts to change in waterproof material configuration aspects, progressively to waterproof material development such as modified pitch, self-adhesion, synthesized polymer materials.At present, Overseas New waterproof material has accounted for more than 90% of the total market size, and product quality, function, life-span have reached a higher level.And China's waterproofing work is since the seventies in last century starts to apply asphalt felt, asphalt waterproof material becomes the leading products of buildings waterproof always, account for about 70% of the total market size in the recent period, high polymer waterproof material only accounts for about 10%, and other are water-repellent paint and other waterproof materials.Polyethylene polypropylene fiber composite sheet is the more welcome waterproof material of one, but existing polyethylene polypropylene fiber composite sheet commercially still also exists many problems, as poor in water resistance, tensile property is low, environment protecting is undesirable, the problem such as loaded down with trivial details of constructing.
Elastomer modified asphalt waterproof roll (SBS) technology that Current Domestic is produced is mature on the whole, but still there is a lot of problem, due in blending process, dosage is accurate not, temperature controlled unstability in oxidizing process, the a series of reasons such as matching method is too outmoded, cause unstable product quality, there is anti-aging, that oxidation resistance is poor, percentage elongation is low, the life-span is short defect.
Summary of the invention
The object of the present invention is to provide a kind of modified asphalt waterproof coiled material, to solve the problems such as common polymer membranes tensile property is low, environment protecting is poor, and the modified asphalt waterproof roll life-span is short.
A kind of modified asphalt waterproof coiled material provided by the invention is achieved through the following technical solutions:
A kind of modified asphalt waterproof coiled material, comprise modified pitch, Polypropylene, PE film, described modified pitch is counted by weight and is synthesized by pitch 40-50 part, high density polyethylene (HDPE) 20-30 part, SBS rubber 15-30 part, stabilizing agent 0.2-2 part, antioxidant 0.5-1 part, light stabilizer 0.1-2 part and filler 10-20 part.
Described stabilizing agent is the composition of one or more and sulphur in vinyl trichlorosilane, VTES and vinyltrimethoxy silane.
Described antioxidant be in butylated hydroxy anisole (BHA), dibutyl hydroxy toluene (BHT), n-propyl gallate (PG), TBHQ (TBHQ) one or more.
Described light stabilizer is benzophenone, BTA and add two or three composition of hindered amine (HAL), can play optimum efficiency that single light stabilizer is beyond one's reach.
Described filler be in calcium carbonate and powdered carbon one or more, order granularity is higher than 700 orders.
The synthetic method of described modified pitch comprises the following steps:
1. asphalt heating is quantitatively joined in blending tank A to 170-180 DEG C later, start agitator when reaching blending tank material level 25%, add the high density polyethylene (HDPE) and SBS rubber that measure;
2. after mixing, be pumped in blending tank B after colloid mill grinding, add the stabilizing agent, antioxidant, light stabilizer and the filler that measure, after stirring 30min, again deliver to mixing in blending tank B after being pumped to colloid mill grinding, quadruplication like this obtains finished product asphaltum;
In building-up process, blending tank A, B temperature remains on 190-200 DEG C, and blending tank A agitator speed controls at 10-20rpm, and blending tank B agitator speed controls at 10-15rpm.
Described polymer-modified asphalt waterproof roll synthetic method step: modified pitch is added in screw extruder, carcass is extruded through screw extruder, while being extruded into carcass, Polypropylene is introduced a counter extensioin roll from both sides simultaneously, by roll pressed, Polypropylene and carcass hot pressing are combined into one, cooling down, finally enclose PE film on surface again, form waterproof roll.
The beneficial effect that the present invention has:
One, high-temperature behavior and low temperature ductility that high density polyethylene (HDPE) and SBS rubber can significantly improve waterproof roll is added, add filler and can effectively make up density contrast inside, and it is dispersed in pitch to adopt melt blending to be more conducive to modifier, improve the storage stability of modified pitch system;
Two, the present invention has higher elongation at break, has good stability, ageing resistance, water proofing property, chemical resistance, weatherability and good mechanical strength, less linear expansion coefficient etc. simultaneously, makes application range of products wide;
Three, the easy easy operation of production process of the present invention, practicality is high.
