Description

High-polymer self-adhesion waterproof coiled material of pre-spread and preparation method thereof
Technical field
The invention belongs to chemical material field for building, and in particular to the high-polymer self-adhesion waterproof coiled material and its system of pre-spread Preparation Method.
Background technology
Adhesive waterproof coil is a kind of very promising waterproof material.Self-adhesive coiled material has that impermeability is good, The features such as low-temperature tenderness strong adaptability, anti-deformation and self-healing property are good, waterproof effect is good, and without heating, cold construction, Directly paving is viscous, both improves efficiency of construction, eliminates disaster hidden-trouble again, receives construction, design and the height of construction unit and praises Reputation.
But for current self-adhered polymer modified bitumen waterproofing membrane, its heat resistance is not high, and hot weather construction occurs Many problems, 70 DEG C are can reach in the sun lower coiled material surface temperature of being exposed to the sun, now coiled material fusing softens, and has trickling trend；And Barrier film is difficult to open, and influences efficiency of construction.National Specification heat resistant requirements are 70 DEG C of fricton-tight tricklings, are rarely had in industry Tack coiled material of the heat resistance more than 70 DEG C.
The content of the invention
, should the technical problem to be solved in the present invention is to provide high-polymer self-adhesion waterproof coiled material of pre-spread and preparation method thereof Coiled material service life is grown, high temperature resistant, is adapted to high temperature region to use.
Technical scheme provided by the invention is to provide the high-polymer self-adhesion waterproof coiled material of pre-spread, with Chopped Strand Mat or polyester felt For reinforcement, reinforcement applied atop modified asphalt layer, mineral grain layer is covered in modified asphalt layer upper surface, is coated below reinforcement Thermoplastic polyolefin layer；
Modified pitch compound layer is arranged between upper covering layer and intermediate matrix layer；The modified pitch compound layer is by following The raw material composition of parts by weight：50~62 parts of pitch, 8~10 parts of efflorescence regnerated rubber powder, 15~25 parts of shoddy, linear low density gather 1.5~2.5 parts of ethene.
The thickness of each layer is respectively：Increase body thickness is 1.0~2.0mm, 1.0~2.0mm of mineral grain layer, thermoplastic poly 0.6~1.5mm of olefin layer, 0.5~1.0mm of modified pitch compound layer.
The preparation method of the modified pitch sizing material is：Now by asphalt heating to 200~220 DEG C, used oil stirring is added Uniform decrease in temperature adds efflorescence regnerated rubber powder to 180~190 DEG C, is warming up to 240~250 DEG C, adds shoddy, and insulation is stirred 2~3h is mixed, linear low density polyethylene is added and continues 0.5~1h of stirring, produce modified pitch sizing material.
The pitch is that asphalt and natural lake asphalt compound, and natural lake asphalt accounts for the 50~100% of pitch total amount.
The needle penetration of asphalt is 80~60, and softening point is 48~55 DEG C, and the content of asphalitine is 15~18%.
The softening point of the natural lake asphalt is 95~110 DEG C, contains 33~38% porous mineral matter, natural lake asphalt The content of studies on asphaltene is 38~43%.
Present invention also offers the preparation method of above-mentioned self-adhered polymer modified bitumen waterproofing membrane, and each layer hot pressing is answered Close, be cooled and shaped, produce.
Compared with prior art, the invention has the advantages that：
1) waterproof roll of the invention, the lake asphalt nitrogen content that weatherability modified pitch used uses is high, and molecular weight is big, Paraffin content is low, and the features such as mineral matter containing active porous shape, assigning asphalt felt has excellent weatherability, stable performance Property, with the adhesiveness of mineral pellet and excellent fire resistance.
2) on the basis of guaranteed price is constant, it is fast to significantly improve current asphalt felt aging speed, mineral pellet It is easy to fall off, the problems such as service life is short.
3) liquid is good by the compatibility of pitch and modifying agent to have good creep properties, self-healing property and cementability, in temperature Spend for 150 DEG C when, show good workability, good completely viscous effect can be formed with basic unit, improves efficiency of construction, Gaseous volatilization pollution on the environment under high temperature is reduced, while also reduces the safety wind that construction action under high temperature is brought Danger.
