Description
Technical field
The present invention relates to a kind of resinoid bond and preparation method thereof more particularly to a kind of hating for rock wool heat-preservation material
Water type fluosilicic modified phenolic resin adhesive and preparation method thereof.
Background technique
Mineral fibrous material, such as rock wool and mineral wool are the inorfil systems manufactured with raw materials such as stone material, ore and clinkers
Product.Such material has excellent insulation, sound absorption and fire protecting performance, and raw material are easy to get, cheap, civilian or industrial build
Heat-insulated and acoustic material is widely used as in building.The preparation method of such fibrous mineral material generally includes following step: first
Inorganic raw material is melted, and by centrifugation, the filament shape mineral fibres of dispersion is made in fused raw material by the methods of blowing, later will
Organic resin binder-impregnated is collected and used to the fiber, solidifies binder at high temperature, and fiber bonder adhesive is become block
Body shape material obtains final mineral fiber product through modes such as excision formings.The excellent sound deadener/insulator of mineral fibrous material
Its very high porosity can be derived from.In the structure of such material, inorfil is intertwine with each other, and mutual by binder
It bonds and forms reticular structure, filled in the cavity of reticular structure by air.These closings or semi-enclosed gas cavity are difficult to
Mutual convection current, and the gas coefficient of heat conduction is extremely low, so that such block materials have good heat-insulating capability, but mineral fibres sheet
It is prepared as materials such as stone material, slags, is essentially all kinds of metal/non-metal hopcalites, substance of this kind is due to table
The presence of face hydroxyl usually all has certain hydrophily.Therefore, after mineral fibrous material is installed and contacts atmosphere, in atmosphere
Steam be formed by liquid water under temperature change and will progress into mineral fibres bulk inner, the semiclosed sky of fill part
Chamber, so that the thermal insulation property of material is decreased obviously.Meanwhile the moisture in mineral fibrous material also results in fibrillar meshwork structure and breaks
It is bad, promote resin degradation, cooperating microorganisms, and destroy the adjacent construction material of mineral fibres.
Currently, the prior art for producing hydrophobic mineral fiber product is to be infiltrated using organic silicon emulsion to mineral fibres
Or sprinkling processing.The method complex steps, productivity is low, and organic silicon emulsion is expensive, so that goods cost rises significantly.
In addition, such hydrophobic layer by physical absorption, is often lost totally, far within the 1-2 year under practical service environment
Less than the life cycle of mineral fiber product.And the reactive hydrophobic agents ingredient of foreign vendor's exploitation at present is with silane coupling agent
Based on, although service life is longer, the price is very expensive, it is difficult to which a large amount of additions use in production.
Chinese patent CN200780045875.1 describes a kind of phenolic resin binder for mineral fibres, feature
It is lower for phenol in the binder and formaldehyde monomers content.Compared with traditional technology, the patent is in rear addition step using single
Ethanol amine is substituted in traditional technology for controlling the urea of content of formaldehyde, leads to the resistance to of rock wool to avoid the thermal decomposition of Lauxite
High-temperature behavior reduces.But phenolic resin adhesive provided by the patent does not have hydrophobic character, if you need to produce waterproof article also
It needs to carry out cumbersome aftertreatment technology.
Chinese patent CN201410603042.4 provides a kind of production method of hydrophobic ore-rock cotton, so-called using its
" hydrophobic liquid " is used as binder, so that product be made to have hydrophobicity.Being somebody's turn to do " hydrophobic liquid " is the common phenolic aldehyde as needed for production rock wool
A certain proportion of hydrophober SILRES BS 1042 is added in resin (to be consulted, for the polysiloxanes of Wacker Chemical Co., Ltd's production
Water-based emulsion), methylcellulose and polyacrylamide solution are formulated, in the curing process, the polysiloxanes in lotion
Particle is adhered to mineral fiber surfaces, provides certain hydrophobicity performance.But additional lotion needs to deploy in production, can only use
With the additional good a few species phenolic resin of emulsion compatibility, modulated " hydrophobic liquid " needs matching while using, and for
Existing rock wool production line also needs addition equipment.In addition, the polysiloxane particle mixed by mechanical stirring with phenolic resin is in reality
It can gradually fall off in the use environment of border, so that product waterproof performance quickly reduces.
Chinese patent CN201410004823.1 describes a kind of lignin rock wool phenolic aldehyde that can provide product waterproof property
Resinoid bond is stirred after being polymerize by lignin phenol formaldehyde resin with dust laying oil and hydrophober.The hydrophobic
Agent is silane resin acceptor kh-550 (3-aminopropyltriethoxysilane).Although certain journey can be provided using silane coupling agent
More long-term hydrophobicity on degree, extends the service life of product, but KH-550 is expensive, and in alkaline aqueous media
Gradually hydrolytic condensation is understood, so that the binder can not store substantially.
(Liu Chenxu, Yan Luting, Liping Wang wait research [J] novel building material of rock wool surface waterproofing coating to research paper
Material, 2013 (6): 45-47.) it describes using methane-siliconic acid sodium water solution sprinkling finished product rock wool material to provide hydrophobicity performance
Method.But this method can only make rock wool surface portion have hydrophobicity, and technique is cumbersome, and productivity is low, raw material sodium methyl silicate
Dosage causes cost to rise significantly very much greatly, and the current stage is also difficult to apply in actual production.
The poor compatibility between phenolic resin and organosilicon moisture repellent exists in the prior art, cannot store, make for a long time
With restricted, and the combination between organosilicon moisture repellent and rock wool heat-preservation material is poor.
Summary of the invention
Problem to be solved: for the above-mentioned deficiency of the prior art, the object of the present invention is to provide one kind to be used for rock wool
The hydrophobic type fluosilicic modified phenolic resin adhesive of thermal insulation material, the mineral fibres system handled using the aqueous resinous binders
Product have good hydrophobic character without processing, can prevent thermal insulation property decline, service life reduction caused by absorbing water as product etc.
Adverse effect, is more suitable for using under high humility high temperature difference environment.
