Abstract
The present invention relates to a laminated roll waterproof material for covering roof of building and is characterized by that on the upper and lower surfaces of waterproof layer there are reinfrocing layers, the water proof layer is made of amixed material composed of ethylene-vinyl acetate copolymer and carbon black; the reinforcing layer is made of polypropylene non-woven fabric. It possesses the advantages of good low temp. flexibility, high tensile strength and low prodn. cost.
Description
The present invention relates to a kind of waterproof roll that covers the building roof, exactly is a kind of sandwich-type waterproof roll.
At present, a kind of by waterproofing course and be compound in sandwich-type waterproof roll that the enhancement Layer on this waterproofing course upper and lower surface constitutes and in building field, obtained more and more widely application, its waterproofing course is mainly made with elastomeric material, haloflex material, and surperficial enhancement Layer is mainly made with glass fabric, polyethylene filament nonwoven; The major defect that this sandwich-type waterproof roll exists is: flexible relatively poor when 1, using under low temperature (below the 20 ℃) condition, and fracture easily; 2, the coiled material of rubber waterproof layer, its waterproofing course thicker (mainly being), thereby manufacturing cost height in order to improve its resistance to tension; The coiled material of oxidic polyethylene waterproofing course, hot strength is low.
The objective of the invention is that a kind of low temperature flexibility is good, hot strength is high, the sandwich-type waterproof roll of low cost of manufacture for people provide.
The object of the present invention is achieved like this, it comprises waterproofing course and is compound in enhancement Layer on this waterproofing course upper and lower surface, be characterized in that the material of manufacturing of this waterproofing course mainly is made up of ethylene-vinyl acetate copolymer 2-5 part (parts by weight), each component of carbon black 0.5-1 part (parts by weight); The material of manufacturing of this enhancement Layer is a nonwoven polypropylene fabric.
Compared with the prior art have the following advantages after the present invention realizes: 1, under-30 ℃ of cryogenic conditions, use flawless and also relatively gentleer, so low temperature flexibility is good; 2, hot strength can reach 11.8Mpa, far above hot strength (3-5) Mpa of prior art, so good mechanical property; 3, cost of the present invention only is 8.7 yuan/m
2, be lower than the cost (10-15 unit/m of prior art
2), so low cost of manufacture.
Following table is seen for details to the testing result that the present invention makes in joint building material product inspection point, Anshan.

Below embodiments of the invention are done explanation in further detail.
1, equipment is prepared
Implement the present invention and need get all the following various production equipment ready:
(1), high-speed mixer model GHL-100
(2), extruder model SB90-160
(3), coated production line one cover
This coated production line design voluntarily, make it comprise following each principal organ successively, this each mechanism is lateral arrangement successively:
The A of mechanism: by being positioned on the frame, and constitute by three motor-driven cylinders of upper, middle and lower position distribution;
The B of mechanism: be positioned at a pair of motor-driven electric heating pressure roller on the frame;
The C of mechanism a: electrothermostat;
The D of mechanism: be positioned at a pair of motor-driven electric heating pressure roller on the frame;
The E of mechanism: be positioned at a motor-driven cylinder on the frame.
2, get the raw materials ready
(1), gets ethylene-vinyl acetate copolymer 20-50kg respectively; Carbon black 5-10kg, plasticizing agent 1-2kg; Antioxidant 0.05-0.1kg; Standby.
(2), it is some, standby to get nonwoven polypropylene fabric.
3, the base-material that is mixed
To go up crust and be equipped with in the various raw material input high-speed mixers, and machine, and mix at normal temperature condition and stirred 5-7 minute, standby.
4, extrude waterproofing course
The base-material that mixes after stirring is added in the extruder, control the machine mouth temperature of this extruder, make it to keep 190 ℃, open extruder, extrude out film shape waterproofing course.
5, compound:
Discharge the nonwoven polypropylene fabric on upper and lower two cylinders that place the A of mechanism simultaneously, and release places the waterproofing course (film) on the cylinder of the A of mechanism middle part, waterproofing course is fed two polypropylene fibre not to be had between the anti-cloth, form interlayer, again this interlayer end is introduced between two pressure rollers of the B of mechanism, start the coated production line, make the interlayer after a roll-in, the C of mechanism constant temperature is handled and the D of mechanism roll-in once more again, afterwards, is wrapped on the cylinder of the E of mechanism.
In this compound working procedure, the roller temperature of maintaining body B is that 110 ℃, the temperature of the C of mechanism are that 110 ℃, the roller temperature of the D of mechanism are 120 ℃ respectively, so, can make finished product.
After the present invention realized, it was not only applicable to the waterproof construction of common flat roof deck, more is applicable to the waterproof construction under the basement wet environment, has the range of application of broad.
When using the present invention to carry out waterproof construction, adopt the cold process construction method, thus easy construction, safety, the production efficiency height, also pollution-free to environment simultaneously, thereby be a kind of more satisfactory waterproof roll.
