Embodiment 1

[0026] A waterproof coiled material, comprising a first waterproof layer, a base layer is bonded to the lower part of the first waterproof layer, and a second waterproof layer is bonded to the lower part of the base layer.

[0027] Specifically, the first waterproof layer and the second waterproof layer are made of the same mixed material.

[0028] Specifically, the thickness of the first waterproof layer is 4 mm, the thickness of the base layer is 1 mm, and the thickness of the second waterproof layer is 1 mm.

[0029] A preparation method of a waterproof coiled material, specifically according to the following steps:

[0030] S1: Preparation of modified asphalt. Coal tar pitch is heated to 250°C in a heating furnace, and then put into the oxidation tower for oxidation treatment. Before oxidation treatment in the oxidation tower, diatomite powder is put into the oxidation tower. The diatomite is made of Raymond mill Grinding with a powder machine to obtain diatomite powder w...

Abstract

The invention discloses a waterproof coiled material and a preparation method thereof. The waterproof coiled material comprises a first waterproof layer, a matrix-base layer is adhered to the lower part of the first waterproof layer, and a second waterproof layer is adhered to the lower part of the matrix-base layer. Common pitch is subjected to oxidation production to get modified by adding diatomite, meanwhile, waste rubber is adopted to be a ductile material of the waterproof coiled material, not only is the production cost lowered, but also the rubber waste difficult to dispose is reused.In addition, the certain proportion of chlorinated polyethylene flame retardant material is added into the waterproof coiled material, and thus the waterproof coiled material has the very good flame retarding effect.

Description

technical field [0001] The invention belongs to the technical field of waterproof materials, and in particular relates to a waterproof coiled material and a preparation method thereof. Background technique [0002] Waterproof membrane is mainly used in building walls, roofs, tunnels, roads, landfills, etc., to resist external rainwater and groundwater leakage, a flexible building material product that can be rolled into rolls. [0003] The existing waterproof membrane products generally do not have flame retardant effect, so when used in some special occasions, if a fire occurs, it may cause certain obstacles to fire protection; at the same time, the existing waterproof membranes often use new materials to maintain their ductility. make the cost increase. Contents of the invention [0004] The object of the present invention is to provide a waterproof coiled material and a preparation method thereof, so as to solve the problems raised in the above-mentioned background tec...
