Problems solved by technology

PVC has many advantages such as good mechanical and physical properties, good thermal deformation performance, good bonding force with self-adhesive adhesive, good elasticity, cold resistance, flame retardancy, wear resistance, chemical corrosion resistance and low leakage of gas and water vapor. Why is PVC not popular What about using as a base material? This is because when using PVC material as the base material, due to the migration of the plasticizer DOP, the base material will soon become hardened, brittle, and turtle-like, resulting in poor waterproof performance, so it cannot be directly used as self-adhesive waterproof The base material of the coil

Embodiment 1

[0027] A base material of self-adhesive waterproof membrane, which is a sheet made of modified PVC material, composed of loose PVC, polyester plasticizer, modifier, filler, stabilizer, lubricant, anti-aging agent and appropriate amount of pigments.

[0028] Specifically: Loose PVC is SG-5 PVC with a degree of polymerization of 1000. The modifier is nitrile rubber. The filler is activated calcium carbonate. The stabilizer is fatty acid salt containing barium and / or lead, and the lubricant is stearic acid material. Antiaging agents are UV absorbers and antioxidants.

[0029] Calculated in parts by weight, the raw material formula of the substrate in the present embodiment is:

[0030] SG-5 type PVC 100;

[0031] Polyester plasticizer 30;

[0032] NBR 5;

[0033] Activated calcium carbonate 5;

[0034] Stabilizer 2;

[0035] Stearic acid 0.2;

[0036] UV absorber 0.2;

[0037] Antioxidant 0.3;

[0038] Just the right amount of pigment.

Embodiment 2

[0040] The base material of this embodiment self-adhesive waterproof roll material, the difference compared with embodiment 1 is that the raw material formula of base material is (calculated by weight):

[0041] SG-5 type PVC 100;

[0042] Polyester plasticizer 80;

[0043] NBR 15;

[0044] Activated calcium carbonate 20;

[0045] Stabilizer 3;

[0046] Stearic acid 0.8;

[0047] UV absorber 0.8;

[0048] Antioxidants 1.2;

[0049] Just the right amount of pigment.

Embodiment 3

[0051] The raw material formula of the base material of the self-adhesive waterproof roll material of the present embodiment is (calculated in parts by weight):

[0052] SG-5 type PVC 100;

[0053] Polyester plasticizer 55;

[0054] NBR 10;

[0055] Active Calcium Carbonate 10;

[0056] Stabilizer 2.5;

[0057] Stearic acid 0.5;

[0058] UV absorber 0.5;

[0059] Antioxidant 0.8.

[0060] An improved self-adhesive waterproof membrane can be made by using the above-mentioned base material: a creeping rubber asphalt self-adhesive adhesive layer and a silicon-coated anti-adhesive isolation film layer are compounded on one or both sides of the base material from the inside to the outside.

[0061] The present invention is embodied in the following aspects to the rationale of PVC modification:

[0062] 1. PVC resin has excellent mechanical and physical properties. After adding an appropriate amount of plasticizer to PVC, the original rigid body can be changed into a flexible...

Abstract

The invention discloses the base material and self-adhering water-proofing coiled material made with the base material. The base material is made by the modified PVC material, comprising PVC, polyester plasticity agent, modifier, filling agent, stabilizer, lubricating agent and antiaging agent. On the surface of base material add creep rubber bitumen self-adhering layer and non-stick coating to get self-adhering water-proofing coiled material. The self-adhering water-proofing coiled material has good physical-mechanical properties, thermal distortion property, elasticity, cold-resistant, flame-proof, abrasion-proof and resistance to chemical attack; it also has low volatility and long life.

Description

technical field [0001] The invention relates to the field of building waterproof materials, in particular to a self-adhesive waterproof roll material made from the base material of the waterproof roll material with single-sided or double-side self-adhesive adhesive. Background technique [0002] At present, the existing waterproof rolls with single-sided or double-sided self-adhesive (and isolation layer), the base material (or tire material, which is a sheet) generally uses polyester felt or PE film material, not PVC. PVC has many advantages such as good mechanical and physical properties, good thermal deformation performance, good bonding force with self-adhesive adhesive, good elasticity, cold resistance, flame retardancy, wear resistance, chemical corrosion resistance and low leakage of gas and water vapor. Why is PVC not popular? What about using as a base material? This is because when PVC material is used as the base material, due to the migration of the plasticizer...
