Problems solved by technology

Under the high temperature exposure, the waterproof membrane absorbs heat and causes the temperature in the house to rise, making people uncomfortable, and some waterproof membranes are not tightly bonded to the cement base, causing rainwater to leak. Leakage does not matter and it costs

preparation example Construction

[0033] The second aspect of the present invention provides a method for preparing a high-performance stretch-resistant nano-modified strong cross membrane, comprising the following steps:

[0034] (1) Preparation of zirconium modified phosphogypsum;

[0035] (2) Preparation of ethyl chloride cured product;

[0036] (3) Preparation of asphalt-based cross-membrane;

[0037] (4) Uniformly couple zirconium-modified phosphogypsum on the surface of the rubber to obtain a self-adhesive layer. Stir the ethyl chloride cured product evenly and then press it into a film and couple it on the asphalt base to obtain a waterproof layer. Use rubber as the film layer Perform compression to obtain high-performance anti-stretch nano-modified strong cross-membrane;

[0038] Preferably, in the step (1): the phosphogypsum is ground in a ball mill for 30 minutes and then taken out, and the phosphogypsum powder is obtained through a 0.075 mm sieve, and the powder and calcium oxide are mixed and for...

Abstract

The invention discloses a high-performance tensile nano-modified strong cross membrane and a preparation method thereof. The high-performance tensile nano-modified strong cross membrane comprises zirconium-modified phosphogypsum, a chloroethane cured product, a mercury nitrate solution, a sodium chloride electrolyte, a tackifier, a softener, a coupling agent and rubber. The surface of the zirconium-modified phosphogypsum has a large number of binding sites, so that the adhesion between the cross membrane and a cement base is enhanced, water permeation is prevented, the zirconium-modified phosphogypsum has hygroscopicity, the density is increased after water absorption saturation, permeation of water molecules is prevented, moisture is evaporated after drying, the density is recovered, and the durability is improved. Chloroethane is hydrolyzed to release heat to evaporate moisture and prevent the moisture from damaging the cross membrane, reaction is performed in the reverse direction after moisture evaporation, a large amount of heat is absorbed, heat on a house is taken away, and the inside of the house is cool. When the cross membrane is on fire, mercurous chloride reacts with diluted hydrochloric acid to generate a mercurous chloride film to cover a fire point, mercury ions absorb heat while oxygen is isolated, the temperature is reduced to be lower than the fire point to extinguish fire, and a fire disaster is prevented.

Description

technical field [0001] The invention relates to the technical field of waterproof coiled materials, in particular to a high-performance stretch-resistant nano-modified strong cross membrane and a preparation method thereof. Background technique [0002] In addition to the surface water we usually use and see on the earth, there are also different types of water such as atmospheric water and groundwater. All kinds of buildings are in contact with these different types of water and will be damaged to varying degrees. Hygroscopic, capillary , Erosion, freezing and thawing will bring harm to the building, not only will affect the use of the building locally, but may even shorten the service life of the building in general. Under the high temperature exposure, the waterproof membrane absorbs heat and causes the temperature in the house to rise, making people uncomfortable, and some waterproof membranes are not tightly bonded to the cement base, causing rainwater to leak. Leakage ...
