Description
Technical field
The invention belongs to construction material and petrochemical technology field, and in particular to a kind of polyethylene polypropylene macromolecule waterproof volume
Material.
Background technology
Polyethylene polypropylene fiber waterproof coiled material belongs to synthetic polymeric waterproofing material series, and it except having synthesis macromolecule completely
Outside all advantages of coiled material, the characteristics of its own is most prominent, it is the network structure on its surface, it is unique makes it have oneself
Performance -- it is cementitious.Because macromolecule composite sheet material can be directly bonded with cement, therefore not by basic unit in work progress
The influence of moisture content, as long as can be constructed without bright water.This is not available for other waterproof rolls.Due to macromolecule composite sheet material
Mark face is coarse, coefficient of friction is big, when hydraulic engineering is applied, directly can be embedded in sand, has enough stability.Due to
Macromolecule composite sheet material can with cement material in process of setting it is directly be bonded, therefore can directly design the structure in cement material
In.
Polyethylene polypropylene fiber waterproof coiled material has construction features：1st, three layers structure, surface enhanced.2nd, sandwich layer -- main water barrier
Branch is employed than LLDPE (LLDPE) of the degree compared with high (macromolecule side chain is more), it is its extensibility, impermeability, soft
Soft, puncture resistance, resistance to low temperature are preferable.3rd, surface is polypropylene fibre (terylene) non-woven fabrics, by compound with sandwich layer, is solved
The big deficiency of polyethylene linear expansion coefficient.The roughness of product surface is added, improves the coefficient of friction of product, and makes Combined roll
The bonding problem of material is addressed, and is realized cementitious.
Polyethylene polypropylene fiber waterproof coiled material product has the advantage that：Cementitious, cold construction, homogenieity is good, and seam conveniently may be used
Overlapped using cement, polyurethane adhesive seam, sweat soldering, cover fillet seam.Ageing-resistant (thering is protection to construct), easily construction, to basic unit
Water content requirement is low, and adaptation engineering project deformation ability is strong, and construction quality fraction is high.
The inferior position that polyethylene polypropylene fiber waterproof coiled material product has：Because of the relatively thin puncture-resistant ability of product, the small complicated base of elasticity
Layer bad adaptability (relative to film), heat resistance are slightly worse (relative to rigid waterproofing).
For a long time, polyethylene polypropylene fiber waterproof coiled material is promoted into a kind of omnipotent waterproof material, roofing, balcony, balcony,
Basement, kitchen and bath, pond etc. can be used, because its is cheap, technique is simple, so being overflowed in construction market.But
Be, this kind of product no matter from the water resistance of material, durability, adapt to basic unit deformability, or the reliability side of construction application
All there is significant deficiency in face, engineering leakage case caused by " nonstandard " material especially inferior is too numerous to enumerate, turns into domestic construction
One of the main reason for engineering leakage rate is high.
According to relevant regulations, polyethylene polypropylene fiber composite sheet, which does not reach certain standard, must not be and be used for grade of setting up defences
It is required that house building roofing engineering and underground waterproof engineering.But reporter visits have been found that on the spot, although regular waterproof
Engineering company is all SBS modified asphalt waterproof coiled materials, but still have part waterproofer in roofing construction and basement construction
Cheng companies are also using polyethylene polypropylene fiber waterproof coiled material for the expense of saving, reduction quantities.
During use, waterproof roll unavoidably can by sunlight, drench with rain, ozone etc. is influenceed, cause material occur aging,
Decompose, water resistance declines；With good thermal aging property, be advantageous to extend the service life of waterproof roll, more preferably
Ground plays its water resistance.
The content of the invention
Present invention aims at a kind of polyethylene polypropylene polymer membranes is provided, there is good hot air aging
Energy.

Dispersant of the present invention, preferred surfactant Span 85.
A kind of polyethylene polypropylene polymer membranes of the present invention, is prepared by the following preparation method：
1) batch mixing：By linear low density polyethylene resin, dispersant, phthalocyanine blue, that activating agent is put into container for stirring is uniform；
2) once heat melts vertical compression：The material being stirred is added in screw extruder, by screw extruder melting extrusion
Resin film, 155-165 DEG C of temperature；
3) second heat melts vertical compression：While extruded resin film, non-woven fabric from both sides is introduced into a counter extensioin roll simultaneously
In, by roll pressed, non-woven fabrics and resin film hot pressing are combined into one, 155-165 DEG C of temperature, form waterproof roll.
Compared with prior art, the present invention has advantages below：
1st, during waterproof roll use, contacted for a long time with strong basicity construction materials such as cement, thus, it is ensured that good
Water resistance, the alkali stability of waterproof roll will necessarily get well.In the prior art, in order to improve the alkaline-resisting stabilization of waterproof roll
Property, some producers are in coiled material production process, to reduce production cost, added into core raw material inorganic based on calcium carbonate
The expensive polyethylene raw material of filler fictitious hosts.However, research shows, although the addition of calcium carbonate can improve to a certain extent
The tensile strength of composite sheet, but the ageing properties of polythene material, particularly artificial weathering aging index can be also influenceed simultaneously.This
Invention can effectively improve the hot air aging index of waterproof roll by increasing activator in being formulated in waterproof roll.
2nd, activator of the invention derives from the residue of plant extracts, many plant extracts, after entering water extraction, one
As be as offal treatment, it is and of the invention, especially choose the plant residue after water extraction, it is residual compared to the plant after alcohol extracting
Slag, water extraction after plant residue in string enrich, day of the present invention by Steam explosion treatment, high-shear homogenizing machine at
Reason, can make full use of vegetation water extract after string in residue, accomplished, to twice laid, to kill two birds with one stone.
