Description
Technical field
The present invention relates to a kind of structure material fields, and in particular to a kind of heat-insulated corrosion resistant lacquer.
Background technique
With the development of society, the raising of people's lives, green building becomes the development trend that building end is come.True stone
A kind of decorative effect of Qi Zuowei exactly likes granite and marmorean biomimetic material, more and more by real estate developer and indoor and outdoor
Designer uses as exterior coating.In modern high-grade decorating outer wall of building, lacquer and traditional tiling and cladding
The advantages of stone is compared, and lacquer is convenient to construct, and cost is relatively low, safe and non-toxic, naturally generous, durable, good decorating effect,
Favor by client.It is base-material that lacquer, which is by one or more synthetic resin emulsions, and a small amount of coalescing agent conduct is added
Binding material is quantitatively adding dispersing agent, defoaming agent, fungicide, more function using the natural colour sand of different gradation or artificial sand as aggregate
Can auxiliary agent, a series of auxiliary agents such as thickener, add a kind of decorative effect that quantitative deionized water is prepared exactly like marble,
The high-quality of the stone materials such as granite, high performance building coating.Lacquer is to form pattern and match volume, reaches sufficiently high
Hardness, and assign a kind of coating of coating lithotome color.Lotion used in lacquer must have good water resistance, bonding
Intensity and resistance to ag(e)ing also want alkali resistance with super strength, Calcium ion stability, dilution steady
Qualitative and freeze-thaw stability.Lacquer have fire prevention, waterproof, anti-soda acid, anti-pollution, nontoxic, tasteless, bonding force is strong, forever
The features such as colour-fast, can effectively stop extraneous adverse circumstances and corrode building, extends the service life of building;Meanwhile true stone
Non-whitening is painted, hardness is high, has protective effect to wall, and harmonious in colour, naturally simple, luxurious elegance is high-end and atmospheric to wait decoration
Effect.Lacquer is very widely used, its decorative effect is more suitable for moulding various designs than stone material comparable to stone material.
Lacquer can be used as exterior wall and embossment, the abnormal shape wall decoration such as beam column;It applies also for doing exterior wall mural painting;In addition to this, may be used also
For interior decoration, Scenic Spots, sacred Buddhist site etc..In recent years, being surging forward in construction market with lacquer, it is special
It is not to have accounted within 2013 the 30% of entire exterior coating in decoration of exterior wall, closely has 1/5th to use very in new building
Mineral varnish and multicolor finish.Lacquer is exactly high with its fidelity, and stone texture is strong, and decorative strong, use is safe, makes
With a series of superior functions and quality-high and inexpensive stone imitation material decorative effects such as service life length, have become Outside Wall Coating for Decorating
In one of leading material.But there are summer easy after tacks for lacquer on the market, are irradiated by ultraviolet light and are easily turned yellow, stain resistant is not
Enough, the problems such as service life is shorter.One of them in lacquer formula the reason is that need to disperse using to a certain amount of dispersing agent
Agent is usually while having lipophilic and hydrophilic interfacial agent, dispersible to be insoluble in the inorganic, organic pigment of liquid
Solid particle, while the sedimentation and cohesion of solid particle can also be prevented, to form stable suspension.However, making when dispersing agent
When dosage is larger, foam may be generated in paint mixture, needs to be added further amounts of defoaming agent and is defoamed, so that formula
While the increased costs of preparation, the property of paint product such as color, viscosity, mixed stability character state etc. also will affect
Matter.Therefore, it is still necessary to which formula is further improved.
