Abstract

The invention discloses a flame-retardant hot-melt pressure-sensitive adhesive and a preparation method thereof. The flame-retardant hot-melt pressure-sensitive adhesive is prepared from the following components in parts by weight: 20-40 parts of a thermoplastic elastomer, 2-4 parts of a halogen-free flame retardant, 1-2 parts of an antioxidant, 5-10 parts of amorphous polyolefin, 20-30 parts of polyolefin resin, 4-6 parts of polyisobutene, 1-2 parts of plasticizer, 1-3 parts of a bio-emulsifier, 50-60 parts of tackifying resin and 3-5 parts of an ultraviolet light absorber. The flame-retardant hot-melt pressure-sensitive adhesive has excellent ultraviolet aging resistance and heat aging resistance as well as good low-temperature bending resistance, has proper cohesive force, stripping force and initial adhesion and has flame retardance; and the defect that a traditional pre-laid waterproof roll can only be constructed above 0 DEG C can be completely avoided.

Description

technical field [0001] The invention relates to the field of adhesives, in particular to a flame-retardant hot-melt pressure-sensitive adhesive and a preparation method thereof. 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 e...
