Problems solved by technology

[0003] After the existing waterproof membrane is used for a long time, the flame-retardant asphalt on the surface will crack and fall off due to external reasons. At this time, the flame-retardant and waterproof performance of the conventional waterproof membrane cannot be guaranteed. Therefore, in order to further ensure waterproof For the actual use of the coil, the flame retardant and waterproof properties of the tire base need higher requirements to meet the practical application

Abstract

The invention discloses a flame-retardant SBS modified asphalt waterproofing membrane and a preparation method thereof. During preparation, polyester felt is used as the base, flame-retardant asphalt is coated on both sides, and the waterproofing membrane is obtained after the film is applied and dried; In this plan, in order to improve the flame retardant performance of the waterproof membrane, this application introduces decabromodiphenyl ethane and antimony oxide with a mass ratio of 1:1 during the preparation of flame retardant asphalt. Antimony works synergistically to improve the flame retardant properties of waterproof membranes. The waterproofing membrane prepared by this application not only has excellent waterproofing performance, but also has excellent flame retardant properties; and when the waterproofing membrane is actually used, when the outer layer of asphalt material falls off and breaks due to external force, the waterproofing membrane still has relatively excellent properties. Excellent flame retardant and waterproof performance, long service life and high practicality.

Description

Technical field [0001] The invention relates to the technical field of waterproofing membranes, specifically a flame-retardant SBS modified asphalt waterproofing membrane and a preparation method thereof. Background technique [0002] Asphalt waterproofing membrane refers to a rolled material made of asphalt material, tire material and anti-adhesive material spread on the surface. It is also called linoleum. Asphalt waterproofing membrane refers to tire-mounted membranes and tireless membranes; any rolled material made of thick paper or glass fiber cloth, asbestos cloth, cotton and linen fabrics and other tire materials impregnated with petroleum asphalt is called tire-mounted membrane ; Mix asbestos, rubber powder, etc. into asphalt materials, and the roll-shaped material made by rolling is called roll-pressed roll material, that is, tireless roll material. [0003] After long-term use of existing waterproofing membranes, the flame-retardant asphalt on the surface will cra...
