Description

A kind of modified asphalt waterproof coiled material
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 start to change in waterproof material configuration aspects, progressively to modification The waterproof material development such as Colophonium, self-adhesion, synthesis macromolecular material.At present, Overseas New waterproof material has accounted for the total market size More than 90%, product quality, function, life-span have reached a higher level.And China's waterproofing work was since 70 years last century Since generation starts to apply asphalt felt, asphalt waterproof material becomes the leading products of buildings waterproof always, accounts for market in the recent period The 70% about of total amount, high polymer waterproof material only accounts for 10% about, and other are water-repellent paint and other waterproof materials.Polyethylene third Synthetic fibre composite of water-proof coiled material is a kind of relatively popular waterproof material, but polyethylene polypropylene fiber composite sheet currently on the market There are still many problems, such as poor waterproof properties, the problems such as tensile property is low, environment protecting is undesirable, construction is loaded down with trivial details.
Elastomer modified asphalt waterproof roll (sbs) technology that Current Domestic produces is mature on the whole, but still suffers from a lot Problem, because, in blending process, dosage is not accurate, temperature controlled unstability in oxidizing process, matching method is excessively old The a series of reason such as old, leads to unstable product quality, there is aging resistance, oxidation resistance is poor, elongation percentage is low, short life Defect.
Content of the invention
It is an object of the invention to provide a kind of modified asphalt waterproof coiled material, to solve common polymer membranes stretching Performance is low, environment protecting is poor, the problems such as modified asphalt waterproof roll short life.
A kind of modified asphalt waterproof coiled material that the present invention provides is achieved through the following technical solutions:
A kind of modified asphalt waterproof coiled material, including modified pitch, Polypropylene, pe film, described modified pitch is by weight Meter is by Colophonium 40-50 part, high density polyethylene (HDPE) 20-30 part, sbs rubber 15-30 part, stabilizer 0.2-2 part, antioxidant 0.5-1 Part, light stabilizer 0.1-2 part and the synthesis of filler 10-20 part.
Described stabilizer is one in vinyl trichlorosilane, VTES and vinyltrimethoxy silane Plant or multiple and sulfur compositionss.
Described antioxidant is Butylated hydroxyanisole (bha), dibenzylatiooluene (bht), propylgallate (pg), one or more in tert-butyl hydroquinone (tbhq).
Described light stabilizer is two or three compositions of benzophenone, benzotriazole and hindered amine (hal), Ke Yiqi To the be beyond one's reach optimum efficiency of single light stabilizer.
Described filler is one or more in Calcium Carbonate and powdered carbon, and mesh granularity is higher than 700 mesh.
The synthetic method of described modified pitch comprises the following steps:
1. Colophonium is heated to 170-180 DEG C to be quantitatively adding in blending tank a later, opens when reaching blending tank material position 25% Dynamic agitator, adds the high density polyethylene (HDPE) measuring and sbs rubber；
2., after mix homogeneously, it is pumped in blending tank b after colloid mill grinds, adds the stabilizer measuring, antioxygen Agent, light stabilizer and filler, after stirring 30min, are pumped to after colloid mill grinds and deliver to mixing in blending tank b again, so instead Multiple four finished product modified pitch；
In building-up process, blending tank a, b temperature is maintained at 190-200 DEG C, and blending tank a agitator speed controls in 10- 20rpm, blending tank b agitator speed controls in 10-15rpm.
Described polymer-modified asphalt waterproof roll synthetic method step: modified pitch is added in screw extruder, warp Cross screw extruder extrusion carcass, while being extruded into carcass, Polypropylene introduced a counter extensioin roll from both sides simultaneously, By roll pressed, Polypropylene is combined into one with carcass hot pressing, cooling down, finally enclose pe film on surface again, formed Waterproof roll.
The invention has the benefit that
First, high density polyethylene (HDPE) and sbs rubber is added can to significantly improve high-temperature behavior and the low temperature ductility of waterproof roll, Add filler can effectively make up density contrast inside, and it be dispersed in Colophonium to be more beneficial for modifying agent using melt blending, Improve the storage stability of modified pitch system；
2nd, the present invention has higher elongation at break, has good stability, ageing resistance, water proofing property, resistance toization simultaneously The property learned, weatherability and preferable mechanical strength, less linear expansion coefficient etc., make application range of products wide；
3rd, production process of the present invention is easy easily operates, and practicality is high.
