Description

Hydrophober and preparation method thereof
Technical field
The present invention relates to a kind of hydrophober and preparation method thereof.
Background technology
Hydrophober is external wall waterproof special-purpose water-proof agent, and it is mainly used in ceramic tile external wall waterproof(Spraying), toilet, kitchen, the ceramic tile such as balcony seam waterproof, concrete wall surface, ceramic tile, stone material, timber, cement surface and road surface waterproof, especially ancient building repair(Temple, church, the site of ancient culture remains of state guarantee)Application there is antiacid alkali, ageing-resistant, anti-carbonization, the accumulation of salt in the surface soil, protection against the tide, mould proof etc..
Hydrophober can be by 1:5 or 1:10 ratios being watered, building surface is sprayed on sprayer, building can be rapidly permeated into, form invisible permanent waterproof layer, played an important role in external wall waterproof, after tile bonding is finished, by hydrophober, it is sprayed on ceramic tile seam and ceramics, completes the lifelong waterproof of exterior wall.
Hydrophober changes traditional external wall waterproof method, from the structure of building material, solve exterior wall leakage root problem, make mortar, concrete voids fine and close, improve resistance to compression, tensile strength, simultaneously form permanent water-resistant film in building surface, warming plate and metope bonding part is not expanded, it is indeformable, do not fall off, can effectively extend Building life cycle.
Building exterior wall heat preserving system is the key link of building energy conservation.Traditional insulation material result in numerous fire due to having used a large amount of inflammable materials, lose very big.Outer wall heat preservation system to be accomplished is really fire-retardant, it is necessary to do insulation material using the inorganic incombustible material such as rock wool, but these inorganic material easily moisture absorption, after the moisture absorption, heat-insulating property drastically declines, and increases weight, causes exterior wall heat-preserving system deformation and fails.
The content of the invention
It is an object of the invention to solve the deficiency that above-mentioned prior art is present, there is provided good hydrophober of a kind of water resistance and preparation method thereof.
The present invention is achieved by the following technical solutions:
Hydrophober is prepared from by the raw material of following weight:Calcium carbonate 32-38 parts, stearic acid 20-26 parts, tetraethyl orthosilicate 8-16 parts, isopropanol 40-46 parts, acetic acid 28-34 parts, alkyl triethoxysilane 14-18 parts, polysiloxanes 27-33 parts, compound emulsifying agent 14-22 parts.
Preferably, hydrophober is prepared from by the raw material of following weight:32 parts of calcium carbonate, 23 parts of stearic acid, 16 parts of tetraethyl orthosilicate, 40 parts of isopropanol, 31 parts of acetic acid, 18 parts of alkyl triethoxysilane, 27 parts of polysiloxanes, 18 parts of compound emulsifying agent.
The compound emulsifying agent is made up of emulsifying agent A and emulsifying agent B;At least one of the emulsifying agent A in sorbitan trioleate, polyoxyethylene~polyoxypropylene block copolymers ether, AEO or Span60;At least one of the emulsifying agent B in polyethylene glycol oxide sorbitan monostearate, APES or polyethylene glycol oxide sorbitan monooleate.
Disclosed herein as well is a kind of preparation method of hydrophober, its concrete preparation process is as follows:By calcium carbonate, stearic acid, tetraethyl orthosilicate, isopropanol mixing, compound emulsifying agent is added after being well mixed, cut into paste simultaneously, the particle diameter and water-soluble of measurement paste, deionized water is added after qualified, simultaneously acetic acid, alkyl triethoxysilane, polysiloxanes are added, target product is obtained.
The hydrophober, there is provided what a kind of cost performance was high disclosure satisfy that the organosilicon moisture repellent of heat preservation rock, mineral wool and perlite, addition processes the hydrophober of the 0.3~0.5% of material dry weight and fully meets GB/T25975-2010 Require, while meeting long-term hydrophobicity performance.
