Description

One kind overlays waterproof roll and preparation method thereof
Technical field
The present invention relates to chemical material fields for building, and in particular to one kind overlays waterproof roll and preparation method thereof.
Background technology
With the acceleration of urbanization process, road traffic congestion phenomenon is also more serious, and limited land resource has been difficult to More populations and construction, development activities are accommodated, the underground space becomes available region.Then, it is empty to develop and utilize underground Between resource become numerous urban developments at present and in the future inevitable choice.At present have been directed to underpass, undergrond street, market, Subway and parking lot etc..But many project is put into practice, and is found aging or drawing crack of base's strain cracking to waterproof layer, is anti- The great disease evil that water layer failure leaks.The cracking of substrate concrete or mortar levelling layer can not avoid, after cracking Stretching is generated to waterproof layer, when waterproof layer and base are firmly bonded complete, waterproof layer is easier by drawing crack, bond it is incomplete, then Channeling water easily occurs.Current many waterproof materials, such as Chinese patent CN101694114A, CN1900207 etc. are dripped using modified Green class adhesive.Such adhesive is easily locally generating stress fatigue, to resisting the scarce capacity of base's strain cracking, moist base Face cannot paste, and binding agent is asynchronous with coiled material bulk properties, overlap and easily disengage.It is poor that waterproof roll is punctured self-healing ability, no The requirement of engineering waterproofing layer function is adapted to completely, and therefore, it is necessary to develop a kind of new material, these of adaptation engineering function will It asks.
Invention content
In view of the deficiencies of the prior art, the invention reside in propose it is a kind of it is improved overlay waterproof roll, material water resistant is oozed Saturating ability is good, and intensity is big, and elongation is big, has good workability.
To achieve the above object, the technical solution adopted in the present invention is：
One kind overlays waterproof roll, and including base material, self-adhesive layer and separation layer, wherein base material is polyethylene kind base material, self-adhesion Layer is hot-fusible pressure-sensitive adhesive, and separation layer uses isolation film or sprinkles special special sand and is made.
Preparation method is：
1) proportioning machine automatic blending
2) it is molded using screw rod heating extruding
3) unit is shaped to coiled material sizing using six roll-in light
4) automatic measuring thickness machine measures coil thickness
5) tempering shaping, natural cooling are heated
6) in one layer of hot-fusible pressure-sensitive adhesive of substrate surface even application
7) one layer of isolation film is covered on hot-fusible pressure-sensitive adhesive or spreads one layer of special sand
8) automatic winding is packed.
Specifically, polyethylene base material is made of high density polyethylene (HDPE) and high-density polyethylene modified dose；Its middle-high density gathers Ethylene selects HDPE-L501, modifying agent selection thermoplastic elastomer (TPE) and thermoplastic resin.
Specifically, by weight, polyethylene base material is mainly made of following components：
40~70 parts of high density polyethylene (HDPE)
35~65 parts of linear low density polyethylene
20~50 parts of thermoplastic elastomer (TPE).
Specifically, thermotropic pressure sensitive glue is SBS, at least two in SEB, SSIS.
Specifically, six roll-in light sizing unit is arranged using S rows in step 3), each roll temperature independence temperature control, from high to low It controls and is：75℃→75℃→60℃→45℃→35℃→35℃.
The beneficial effects of the invention are as follows：
(1) present invention is sanded the high-end automation equipment of integration using extrusion moulding and gluing, greatly improves production efficiency Rejection rate is reduced, and according to manufacturing technique requirent, accomplished that technic index is stringent, accurate, and operate, technological parameter letter is set It is single；
(2) there is good chemical-resistance, water-tolerant, freeze thawing resistance and acid-alkali-corrosive-resisting, and tough coating The erosion of various water environments can be resisted；
(3) intensity of coiled material is high, and elongation percentage is big, small by temperature Change contraction, and high resilience, adapts to base course crack and rolls up Material does not crack；It has good workability, easy construction, reliable, safety are environmentally safe, and open fire is used especially suitable for not allowing The place of construction.
