Problems solved by technology

Asphalt waterproofing membrane is a rollable sheet waterproof material made by dipping asphalt on the base tire and then spreading powder or flake isolation material on the surface; the construction of self-adhesive waterproofing membrane does not need to use open flames. An environment-friendly waterproof material, which is widely used in waterproofing projects of various civil and industrial buildings. Ordinary self-adhesive membranes do not have the performance of heat insulation and cannot be used outside. When exposed to the sun, the internal temperature of the membrane exceeds the ambient temperature. 20°C, it is very easy to age, hollow and crust. The current method is to apply a protective layer after the construction is completed, and the protective layer will cause difficulties in later maintenance. If there is a leak point, it is necessary to shovel off the protective layer first and then deal with waterproofing layer, the maintenance time is long and the maintenance cost is very high, and on some special roofs, such as metal roofs, roofs that cannot bear weight, etc., it is not suitable for cement protective layers. Poor, and it must be heated by an open flame for construction; while ordinary adhesives have poor bonding effect on difficult-to-bond polyolefin materials, and their high temperature resistance is not strong

Embodiment Construction

[0020] The self-adhesive waterproof membrane of the present invention is prepared from the following components by weight:

[0021] Asphalt 4000kg, rubber oil 1200kg, styrene-based thermoplastic elastomer 400kg, styrene-butadiene rubber 200kg, tire rubber powder 1350kg, talcum powder 2850kg, polyester tire 200g.

[0022] The first step: melt the asphalt first, then weigh and measure it, and take 4000kg;

[0023] The second part: Then weigh 1200kg of rubber oil, 400kg of styrene-based thermoplastic elastomer, 200kg of styrene-butadiene rubber, 1350kg of tire rubber powder, and 2850kg of talcum powder, and then grind and stir the weighed materials with molten asphalt, and finally get SBS mixture, and then inspect the SBS mixture obtained by stirring;

[0024] Step 3: Unroll the polyester tire at the same time, and then store the polyester tire;

[0025] Step 4: Then dry the polyester tire, and then prepreg the polyester tire;

[0026] The fifth step: coating the SBS mixture o...

Abstract

The invention discloses a formula of a self-adhesive waterproof coiled material. The formula comprises asphalt, rubber oil, a styrene thermoplastic elastomer, butadiene styrene rubber, tire rubber powder, talcum powder, a polyester tire, 4000 kg of asphalt, 1200 kg of rubber oil, 400 kg of a styrene-series thermoplastic elastomer, 200 kg of butadiene styrene rubber, 1350 kg of tire rubber powder,2850 kg of talcum powder and 200 g of a polyester tire. The invention relates to a self-adhesive waterproof coiled material and a production process thereof, and belongs to the field of building materials. In the material, the rubber oil has the characteristics of improving the elasticity, the flexibility, the processability and the mixing property of rubber; the viscosity, rigidity, softening temperature and cohesion bonding strength of the material can be strictly controlled and changed by the styrene thermoplastic elastomer; and talcum powder has excellent physical and chemical characteristics of lubricity, fire resistance, acid resistance, insulativity, high melting point, inactive chemical property, good covering power, softness, good gloss, strong adsorption capacity and the lik. Inconclusion, the construction of the waterproof roll is facilitated, and meanwhile the bonding effect and the high-temperature resistance of the waterproof roll are improved.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a self-adhesive waterproof coiled material and a production process 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, as an engineering basis There is no leakage connection with the building. It is the first barrier for waterproofing the whole project and plays a vital role in the whole project. According to the different carcass, it can be divided into non-carcass coils and carcass coils. Waterproof membrane requires good water resistance, stability to temperature changes, certain mechanical strength, elongation and fracture resistance, certain flexibility and aging resistance, etc. Waterproof membrane is a kind of rollable Sheet-shaped waterproof material is one of the impor...
