Embodiment 1

[0010] Waterproof roof adhesive is composed of the following raw materials in weight percentage: 65% asphalt, 25% coal tar, 3% waste polystyrene foam, 5.5% quicklime, and 1.5% sawdust. When preparing, firstly, the waste polystyrene foam is crushed into particles Then put coal tar in the container, heat to 650°C, then add asphalt, stir evenly and continue to heat up to 750°C, after the asphalt dissolves, cool down to 400°C, then add waste polystyrene foam, quicklime and The sawdust is stirred evenly and cooled into a paste to obtain the waterproof roof adhesive of the present invention. When in use, reheat it to about 500°C to melt it.

Embodiment 2

[0012] The waterproof roof adhesive is composed of the following raw materials in weight percentage: 75% of asphalt, 15% of coal tar, 6% of waste polystyrene foam, 3.5% of quicklime, and 0.5% of sawdust. When preparing, firstly, the waste polystyrene foam is crushed into particles Then put coal tar in the container, heat to 700°C, then add asphalt, stir evenly and continue to heat up to 750°C, after the asphalt dissolves, cool down to 500°C, then add waste polystyrene foam, quicklime and The sawdust is stirred evenly and cooled into a paste to obtain the waterproof roof adhesive of the present invention. When in use, reheat it to about 500°C to melt it.

Embodiment 3

[0014] Waterproof roof glue is composed of the following raw materials in weight percentage: 70% of asphalt, 20% of coal tar, 5% of waste polystyrene foam, 4% of quicklime, and 1% of sawdust. When preparing, firstly, the waste polystyrene foam is crushed into particles Then put coal tar in the container, heat to 680°C, then add asphalt, stir evenly and continue to heat up to 750°C, after the asphalt dissolves, cool down to 450°C, then add waste polystyrene foam, quicklime and The sawdust is stirred evenly and cooled into a paste to obtain the waterproof roof adhesive of the present invention. When in use, reheat it to about 500°C to melt it.

Abstract

The invention relates to a building waterproof material, in particular to a waterproof roof adhesive, which aims to solve the problems in prior roof waterproof material of poor weatherability, easy bubbling and peeling, and poor permeability and air permeability, comprising asphalt, coal tar, waste polystyrene foam, lime and sawdust. Firstly, the waste polystyrene foam is ground to particles; secondly, the coal tar is added into a vessel and heated to 650 to 700 degrees; and the asphalt is added into the vessel, and then the former mixture is agitated homogeneously and keep on warming up to 750 degrees, after the asphalt is dissolved, the mixture is cooled to 400 to 500 degrees; at last, waste polystyrene foam, lime and sawdust are added into mixture successively, the mixture is agitated homogeneously and cooled to a paste shape, and then the finished product is obtained. The building waterproof material has the advantages that: the building waterproof material integrates the advantages of waterproof, heat preservation and heat insulation and has admirable waterproof and heat preservation effect, good weatherability, no fluid and cracks, high adhesive strength; meanwhile, the material meet the national specified standard; more importantly, the aim of waste reuse, pollution treatment, environment protection and cost saving are realized by using the waste polystyrene foam.

Description

technical field [0001] The invention relates to a waterproof material for construction, in particular to a waterproof roof glue. Background technique [0002] At present, construction projects mostly use waterproof coiled materials for anti-seepage, especially roof waterproof and plugging treatment, and asphalt felt is more commonly used, and asphalt felt is easy to flow when it is heated in summer, and it is easy to be brittle in winter when it is low temperature. , so it is easy to leak and the waterproof life is short. With the continuous development of technology in this field, some new materials have appeared in building waterproof engineering, such as various modified asphalt waterproof materials such as rubber-asphalt roof waterproof materials, elastic asphalt, neoprene latex asphalt, etc., due to the properties of these materials. It is determined that asphalt and polymers do not have the ability to penetrate the roof structure layer. After construction, the waterpr...
