[0004] 1. It is well known that asphalt itself is a cold and brittle material with heat flow, so modified asphalt adhesives have poor high and low temperature resistance, which brings troubles to construction in summer and winter;
[0005] 2. The surface of the coil is not treated, and the feet are sticky, so workers cannot bind steel bars on the surface of the coil;
[0006] 3. There is no protective layer on the surface of the coiled material. If the construction period is delayed, under the action of ultraviolet rays and wind and rain, the bonding effect will be lost and the product will be scrapped;
[0007] 4. The bonding and peeling strength of the modified asphalt adhesive is low;
[0011] However, the existing hot-melt pressure-sensitive adhesives have the following deficiencies: 1. The most common ones are insufficient high and low temperature resistance, poor water resistance, and many defective products; And the influence of humidity changes in the morning and evening, the bonding fastness cannot be guaranteed; 3. The low temperature will significantly reduce the adhesive force of the hot-melt pressure-sensitive adhesive, and the coil cannot be constructed; 4. The weather resistance is not enough, and UV resistance is also an important indicator. Considering the aging phenomenon caused by sunlight exposure during construction; 5, and there is no hot-melt pressure-sensitive adhesive with flame-retardant properties in the prior art

Abstract
The invention relates to flame-retardant hot-melt pressure-sensitive adhesive and a preparation method thereof. The pressure-sensitive adhesive is a product developed for the waterproof industry. The flame-retardant hot-melt pressure-sensitive adhesive comprises the following raw materials in percent by weight according to a formula: 20-35% of a thermoplastic elastomer, 0-5% of amorphous polyolefin, 5-10% of polyisobutylene, 25-40% of first tackifying resin, 5-10% of second tackifying resin, 10-20% of a plasticizer, 0.1-1% of a coupling agent, 0.1-1% of an ultraviolet absorber, 0.1-1% of an antioxidant and 5-10% of a flame retardant. The flame-retardant hot-melt pressure-sensitive adhesive provided by the invention not only has excellent ultraviolet aging resistance, heat aging resistance and low temperature bending resistance and has proper cohesion, release force and Initial adhesion, but also has flame retardance and can perfectly overcome the defect that the conventional pre-laid waterproof roll can be constructed only above 0 DEG C.
Description
technical field [0001] The invention relates to a flame-retardant hot-melt pressure-sensitive adhesive, its preparation method and application. Background technique [0002] With the acceleration of urbanization, limited land resources have been difficult to accommodate more population and construction and development activities. Therefore, the development and utilization of underground space resources has become an inevitable choice for the current and future development of many cities. At present, the utilization of underground space has involved: underground commercial facilities, underground parking lot stations, underground reservoirs, subways, comprehensive pipe corridors, etc. However, the impact of water channeling, leakage and settlement in underground waterproofing projects is still a major problem that plagues waterproofing experts and users. How to provide direct full-bonded waterproofing protection for structural concrete is extremely challenging. [0003] At...
