Description
Technical field
The present invention relates to a kind of PVC polymer membranes, belong to architectural waterproof material technical field.
Background technology
Polyvinyl chloride, English abbreviation PVC (Polyvinyl chloride) are vinyl chloride monomer (vinyl chloride
Monomer, abbreviation VCM) in initiators such as peroxide, azo-compounds；Or Raolical polymerizable is pressed under light, heat effect
The polymer that mechanism is polymerized.Ryuron and vinyl chloride copolymer system are referred to as vinyl chloride resin.PVC is amorphous
The white powder of structure, the degree of branching is smaller, relative density 1.4 or so, 77-90 DEG C of glass transition temperature, and 170 DEG C or so start point
Solution, it is poor to the stability of light and heat, in 100 DEG C or more or through a long time exposure in sunshine, it will decompose and generate hydrogen chloride, go forward side by side
One step autocatalysis decompose, cause to change colour, physical mechanical property also declines rapidly, must be added in practical applications stabilizer with
Improve the stability to light and heat.
Industrial PVC molecular weight generally in 50,000~110,000 ranges, have larger polydispersity, molecular weight with
The reduction of polymerization temperature and increase；Without definite melting point, 80-85 DEG C starts to soften, and 130 DEG C become viscoelastic state, and 160~180 DEG C are opened
Beginning is changed into viscous state；There are preferable mechanical performance, tensile strength 60MPa or so, 5~10kJ/m2 of impact strength；Have excellent
Dielectric properties.PVC was once the maximum general-purpose plastics of yield in the world, in architectural engineering PVC waterproof roll roofing,
It is used widely lower room etc..
However in the prior art, plasticizer used in the dispensing of polyvinylchloride waterproof roll, filler, lubricant,
The defects such as the match ratios such as antiaging agent are unreasonable, loss of properties on aging, and elasticity is not flexible enough, and elongation at break is low, directly affect
Waterproof service life.
Invention content
The purpose of the present invention is to provide a kind of PVC polymer membranes, energy overcome the deficiencies in the prior art improves volume
The service life of material increases the flexibility of coiled material, elongation percentage, corrosion-resistant, acid-proof alkaline.
The purpose of the present invention is achieved through the following technical solutions：A kind of PVC polymer membranes, it is by following
The material of parts by weight forms：10-20 parts of polyvinyl chloride, 5-10 parts of oxidic polyethylene, 5-10 parts of polyethylene, powdered whiting 20-
40 parts, 5-10 parts of stearic acid, 2-5 parts of stabilizer, 3-7 parts of barium sulfate, 15-30 parts of technical white oil, 0.5-2 parts of filler material, defoaming
0.1-0.5 parts of powder；
Above-mentioned material is put into blender, is uniformly mixed, inside elevator to micro- material machine, is heated up to 120-
190 DEG C, it is cooled to 70-90 DEG C after being come out by molding machine, until forming extruder goes out sheet material, traction is rolled up to crimping machine at waterproof
Material.
The stabilizer is zinc stearate.
The granular size of the powdered whiting is 400-1000 mesh.
The present invention is to allow polyvinyl chloride to be changed into viscous state in the environment of 120-190 DEG C and be equipped with other stabilizers, is used
In enhancing its heat resistance, flexibility, ductility is good, easily molded, less brittle, nontoxic and pollution-free, and service life is long, corrosion-resistant, has
Very strong adhesive effect.
Oxidic polyethylene has good thermal stability, and high-temperature volatile is low, and to filler, the dispersibility of pigment is splendid, i.e.,
There is extremely excellent external lubricity, and there is stronger internal lubrication to act on, also there is coupled action, improves the production effect of plastic processing
Rate reduces production cost；Polyethylene has excellent resistance to low temperature, the erosion of acid and alkali-resistance；Powdered whiting is produced for increasing
The filler of product reduces production cost, is ideal filler material；Stearic acid is PVC heat stabilizer, has good lubricity, heat steady
It is set for using, helps that the coking during heating, defence is prevented to be placed in finished product discoloration caused in sulfide cruelly；Zinc stearate
As stabilizer, inhibit initial coloring and lubricity good, no sulfide staining；Barium sulfate has high fillibility, low abrasion, pole
The fineness of good glossiness and particle so that protected in sheet material exposure for a long time, increase colour stability；Technical white oil has
There is mixed lubrication effect.
The waterproof roll that the present invention obtains, Testing index are as follows：
| Serial number | Project | Index |
| 1 | Tensile strength Mpa | 12.9 |
| 2 | Elongation at break % is greater than or equal to | 356 |
| 3 | Heat treatment size changing rate % is greater than or equal to | 2.1 |
| 4 | Low-temperature bending is flexible | - 35 degree flawlesses |
The beneficial effects of the present invention are：By being equipped with multiple auxiliary materials, this hair using PVC material as major ingredient in pyroreaction
Bright flexibility is good, and elongation percentage is high, and corrosion-resistant, acid and alkali-resistance improves the service life of coiled material.
