Problems solved by technology

However, because SBS thermoplastic elastomer contains more unsaturated bonds, these unsaturated bonds will cause SBS to decompose at about 170-180 ° C, so the peel strength of the coil will be greatly reduced in an environment with too high temperature; in addition The oil leakage phenomenon of SBS is relatively serious, the low temperature flexibility is poor, and it is easy to lose adhesion quickly, so the aging resistance is poor and the peel strength is low

Embodiment 1

[0034] Non-bituminous pressure-sensitive self-adhesives consist of the following components:

[0035]

[0036] Wherein, the antioxidant is the B225 type antioxidant produced by BASF; the coloring agent is the coloring agent for the coil rubber material produced by BASF, because the coloring agent is only used to adjust the color of the rubber material, it is known to those skilled in the art to select different colors Colorants will produce different coloring effects, so I won't repeat them here.

[0037] Non-bituminous self-adhesive membranes made from non-bituminous pressure-sensitive self-adhesives.

Embodiment 2 5

[0039] The difference from Example 1 is that the addition amount of each component of the non-bitumen pressure-sensitive self-adhesive adhesive and the addition amount of polybutene are different. The components of Examples 1 to 5 and the performance tests of the non-bitumen self-adhesive coil The results are shown in Table 1.

Abstract

The invention discloses non-asphaltic pressure-sensitive self-adhesive glue which comprises, by weight, 70-120 parts of SEPS (styrene ethylene / propylene styrene block copolymer) thermoplastic elastomer, 60-75 parts of first polybutylene with the molecular weight lower than 1000, 18-24 parts of second polybutylene with the molecular weight of 1000-3000, 10-13 parts of high molecular weight polybutylene, 55-70 parts of naphthenic oil, 150-230 parts of C5 petroleum resin, 4-10 parts of polymer modifiers, 72-100 parts of fillers, 1.7-5 parts of antioxidants and 2-5 parts of coloring agents. A waterproof roll material prepared from the non-asphaltic pressure-sensitive self-adhesive glue has good thermal aging resistance and high peeling strength.

Description

technical field [0001] The invention relates to the production field of waterproof coiled material for construction, more specifically, it relates to a non-bitumen pressure-sensitive self-adhesive adhesive and a waterproof coiled material made from it. Background technique [0002] Traditional waterproof membranes generally use modified asphalt as the main material, and the performance of modified asphalt directly affects the performance of the membrane. Asphalt waterproofing membrane has good hydrophobicity, cohesion and ductility, and is cheap, so it is widely used. However, due to the poor saturation of asphalt itself, the temperature stability of asphalt waterproofing membrane is poor, it is easy to crack in winter, easy to flow in summer, and its strength is low. In addition, there are harmful substances such as pyridine and phenol in asphalt, which have a strong smell during use. Therefore, more and more users tend to use non-bituminous waterproofing membranes. [0...
