Description

Polyethylene polypropylene polymer membranes
Technical field
The invention belongs to construction material and petrochemical technology field, and in particular to polyethylene polypropylene polymer membranes.
Background technology
Polyethylene polypropylene fiber waterproof coiled material belongs to synthetic polymeric waterproofing material series, it except having synthesis macromolecule completely Outside all advantages of coiled material, the characteristics of its own is most prominent, be the net structure on its surface, and it is unique to make it have oneself Performance -- it is cementitious.Because macromolecule composite sheet material can be directly bonded with cement, therefore in the construction process from basic unit The influence of moisture content, as long as can construct without bright water.This is not available for other waterproof rolls.Due to macromolecule composite sheet material Mark face is coarse, friction coefficient is big, in hydraulic engineering in application, can directly 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 linear low density polyethylene (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 friction coefficient 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 energy force difference 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 overflowing 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 are significant deficiency, engineering leakage case caused by " nonstandard " material especially inferior is too numerous to enumerate, becomes domestic construction in face 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 inevitably can be subject to sunlight, drench with rain, ozone etc. is influenced, cause material occur aging, Decompose, water resistance declines；With good thermal aging property, be conducive to extend the service life of waterproof roll, more preferably Ground plays its water resistance.
The content of the invention
Present invention aims at polyethylene polypropylene polymer membranes is provided, there is good thermal aging property.
Polyethylene polypropylene polymer membranes of the present invention, is made of the component of following parts by weight：
92.0-95.0 parts of linear low density polyethylene resin, 0.5-1.5 parts of phthalocyanine blue, 0.1-0.5 parts of dispersant, activity 5.0-8.0 parts of agent；
The activator is obtained by following preparation method：
1. Steam explosion treatment：The Siraitia grosvenorii residue that water was extracted, is put into the processing of steam blasting tank；
2. high-shear homogenizing machine is handled：The pure water of the weight such as 1. material that step is obtained, addition, passes through high shear homogeneous Machine processing, activator is obtained after dry.
Of the present invention to be put into the processing of steam blasting tank, preferably burst pressure 3.0-3.5Mpa, the dwell time maintains 150-200s。
High-shear homogenizing machine processing of the present invention, preferred linear velocity 30-40m/s, time 3-5min.
Drying of the present invention, is preferably dried to moisture below 5%.
Dispersant of the present invention, preferred surfactant Span 85.
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 at the same time In, by roll pressed, non-woven fabrics and resin film hot pressing are combined into one, 155-165 DEG C of temperature, forms waterproof roll.
Compared with prior art, the present invention has the following advantages：
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 be got 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 polyethylene raw material of filler fictitious hosts costliness.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 can be also influenced at the same time, it is particularly artificial weathering aging index.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, into after crossing 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 plant fiber 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 plant fiber in residue, accomplished, to waste utilization, to kill two birds with one stone.
