Abstract
The invention discloses a water repellent, a preparation method therefor and an exterior wall thermal-insulation material. The water repellent comprises the following components in parts by weight: 55-65 parts of polysiloxane, 0-5 parts of alkyl triethoxysilane, 0-5 parts of a C12-13 iso-tridecanol polyoxyethylene emulsifier, 0.1 part of a mildew preventive, 0.5 part of a defoaming agent and 24.4-44.4 parts of deionized water. The invention provides an organic water repellent with high cost performance, which is suitable for thermal-insulation rock wool, mineral wool and perlite; the GB/T25975-2010 requirements are completely met by adding the water repellent which accounts for 0.1-0.5% of the dry weight of the treated materials; and the long-term hydrophobic property is met.
Description
Technical field
The application belongs to building material technical field, particularly relates to a kind of hydrophober and preparation method thereof, external-wall heat-insulation material.
Background technology
Building exterior wall heat preserving system is the key link of building energy conservation.Traditional lagging material, owing to employing material inflammable in a large number, result in numerous fire, loses very large.Accomplish that outer wall heat preservation system is really fire-retardant, the inorganic non-combustible materials such as rock wool must be used to do lagging material, but these inorganic materials very easily moisture absorption, after the moisture absorption, heat-insulating property sharply declines, and gains in weight, and causes exterior wall heat-preserving system deformation and failure.
Summary of the invention
The object of the present invention is to provide a kind of hydrophober and preparation method thereof, external-wall heat-insulation material, to overcome the problems of the prior art.
For achieving the above object, the invention provides following technical scheme:
The embodiment of the present application discloses a kind of hydrophober, comprises polysiloxane 55-65 part, alkyl triethoxysilane 0-5 part, C12-13 isomery alcohol polyoxy second rare emulsifying agent 0-5 part, mould inhibitor 0.1 part, defoamer 0.5 part and deionized water 24.4-44.4 part by weight.
Correspondingly, disclosed herein as well is a kind of preparation method of hydrophober, by polysiloxane and alkyl triethoxysilane mixing, emulsifying agent is added after mixing, cut into paste simultaneously, measure particle diameter and the water-soluble of paste, after qualified, add deionized water, mould inhibitor and defoamer are added simultaneously, obtain target product.
Disclosed herein as well is a kind of external-wall heat-insulation material, comprise described hydrophober.
Preferably, in above-mentioned external-wall heat-insulation material, the dry weight of described hydrophober is 0.1 ~ 0.5%.
Preferably, in above-mentioned external-wall heat-insulation material, this external-wall heat-insulation material is OF 6142 rock mineral wool, glass or pearlstone.
Compared with prior art, the invention has the advantages that: the invention provides the organosilicon moisture repellent that can meet heat preservation rock, mineral wool and perlite that a kind of cost performance is high, the hydrophober adding 0.1 ~ 0.5% of process material dry weight meets GB/T25975-2010 requirement completely, meets long-term hydrophobicity performance simultaneously.
Embodiment
The present invention is described further by the following example: according to following embodiment, the present invention may be better understood.But those skilled in the art will readily understand, concrete material ratio, processing condition and result thereof described by embodiment only for illustration of the present invention, and should can not limit the present invention described in detail in claims yet.
Present embodiment discloses a kind of OF 6142 rock mineral wool, glass or pearlstone hydrophober: comprise polysiloxane 55-65 part, alkyl triethoxysilane 0-5 part, C12-13 isomery alcohol polyoxy second rare emulsifying agent 0-5 part, mould inhibitor 0.1 part, defoamer 0.5 part and deionized water 24.4-44.4 part.
Its preparation method comprises: after polysiloxane and alkyl triethoxysilane mixing, add emulsifying agent after mixing, within 15 ~ 30 minutes, becomes paste with high-shear simultaneously.Survey particle diameter and the water-soluble of paste, deionized water is added after qualified, mould inhibitor and defoamer are added simultaneously, the oyster white liquid obtained has excellent hydrophobic nature on rock wool, glass, note during interpolation testing with phenolic compatible, namely order of addition detects, and inappropriate order of addition will cause floss to produce, the hydrophobic nature of adding 0.1 ~ 0.5% of process material dry weight meets GB/T25975-2010 requirement completely, meets long-term hydrophobicity performance simultaneously.
Adopt GB/T 10299-2011 experimental technique to test above-mentioned hydrophober, measuring its hydrophobic rate is 99.7%.
Finally, also it should be noted that, term " comprises ", " comprising " or its any other variant are intended to contain comprising of nonexcludability, thus make to comprise the process of a series of key element, method, article or equipment and not only comprise those key elements, but also comprise other key elements clearly do not listed, or also comprise by the intrinsic key element of this process, method, article or equipment.
