Abstract
The present invention provides a waterproof agent which is prepared from 1 to 4% of sodium hydroxide, 3 to 8% of ethanol, 2.5 to 3.5 % of monomethyl trichlorosilane and water as the rest. The present invention is non-volatile and non-burning liquid, and has strong permeability and good ventilation property. When the waterproof agent is used in construction, the waterproof agent is sprayed on an area of a building by a low-pressure sprayer, and the area needs to be treated by a waterproof method. The present invention has the advantages of good waterproof effect, long service life and low cost.
Description
What the present invention relates to is a kind of water-proof material.
On the roof of buildings, position such as toilet all will carry out WATER REPELLENT.Used water-proof material mainly is pitch, linkrusta etc. now.To make the position layering asphalt and the malthoid ply of paper of WATER REPELLENT during construction at needs.Difficulty of construction is big, and the labour intensity height pollutes easily, and the work-ing life of waterproof layer is short.In order to address this problem, also there are some new waterproof paints to occur.These waterproof paints also are to be coated in the surface that needs waterproof, will need the building surface of waterproof to cover by water-proof material, reach the waterproof purpose.After situations such as waterproof layer is aging, breakage took place, its waterproof effect will reduce or disappear.Therefore its waterproof effect is still undesirable, and work-ing life is shorter, and cost is higher.
The object of the present invention is to provide a kind of good water-proof effect, long service life, the water-resisting agent that cost is low.
The object of the present invention is achieved like this: it is that the water of sodium hydroxide 1-4%, ethanol 3-8%, monomethyl trichlorosilane 2.5-3.5% and surplus is formed by weight ratio.
Water-resisting agent of the present invention has following characteristics: it is a kind of non-volatile, incombustible liquid, has stronger perviousness.Adopting low-pressure sprayer to be sprayed at the zone that need carry out WATER REPELLENT during construction gets final product.Be sprayed onto the surface of buildings when this water-resisting agent after, can arrive interior surface 10-20mm by rapid permeability, alkaline matter inner with it produces the dehydrated crosslinking reaction, portion expands rapidly within it, the capillary channel that stays when the micropore of resultant energy obstruction and oversite concrete, sand-cement slurry, masonry inside and water evaporates, thus improve its degree of compactness, resistance to compression, tensile strength, and can compensate sand-cement slurry and concrete contraction, increase expansion and contraction, thereby produce waterproof, impervious effect efficiently.Blow and beat on buildings when rainwater, rainwater can be globule shape and trickle naturally, and it is not saturating to drip.Simultaneously have air permeability and good again, moisture can outwards distribute without barrier, can avoid because of moisture-induced expansion, play drum, be full of cracks, distortion, weathering, reaches the purpose of lifelong waterproof.Functions such as that product of the present invention also has concurrently is early strong, diminishing, corrosion resistant, freeze proof, anti-wiping, wear-resisting, high temperature resistant, anti-aging, the degree of compactness that can increase goods, toughness expansion and contraction.Can be widely used in waterproofing works such as roofing, flooring, metope, toilet, boiled water room, tank, water tower, vault, subway, tunnel, cement highway, airstrip, hydro project, bridge, harbour, sewage work, agriculture channel, ceramic tile seam.Also can be used for ancient building, historical relic, archives, martyrs' park etc. and locate anticorrosion, guarantor's look.Can also be as the hydrophober of some lagging material.
For example the present invention is done more detailed description below: get raw material ready by weight the ratio that is the water of sodium hydroxide 1-4%, ethanol 3-8%, monomethyl trichlorosilane 2.5-3.5% and surplus, sodium hydroxide, ethanol, monomethyl trichlorosilane are dissolved into make product of the present invention in the water.
Get raw material ready by weight the ratio that is the water of sodium hydroxide 3%, ethanol 6%, monomethyl trichlorosilane 3% and surplus, sodium hydroxide, ethanol, monomethyl trichlorosilane are dissolved into make product of the present invention in the water.
Get raw material ready by weight the ratio that is the water of sodium hydroxide 2%, ethanol 5%, monomethyl trichlorosilane 3% and surplus, sodium hydroxide, ethanol, monomethyl trichlorosilane are dissolved into make product of the present invention in the water.
Sodium hydroxide in above-mentioned each example adds with the form of sheet alkali.
