Description
Technical field
The present invention relates to paint field, and in particular to a kind of reaction film-forming inorganic dry powder paint for inner wall decoration and its
Production method.
Background technology
With society and the development and progress of modern science and technology, people increasingly pay close attention to shadow of the living environment for health
Ring.It is more and more high for the cry of the low emission even zero-emission of indoor coating VOC (VOC).All buildings
Coating is all made up of three parts：Film forming matter, filler and auxiliary agent.Film forming matter plays a part of bonding agent, and its function is shape
Into continuous or quasi-continuous film；Filling packing plays wear-resisting, scratch resistance in film forming matter, reduces the effect such as cost；Auxiliary agent is then
Play some performances of adjusting coating（Such as rheological characteristic, mildew resistance）Effect.Now widely used interior wall coating is emulsion paint, nothing
By which kind of emulsion paint using high molecular synthetic resin as film forming matter, low VOC indexs are extremely difficult to.In the market also has some low
The VOC even naval stores of Diamond Search, but it is all expensive.In addition, emulsion paint is suspended liquid system, solid content is mostly left 50%
The right side, remaining is water or other solvents.Therefore, the cost of transportation of at least half has been used to carry the water or molten finally to be vapored away
Agent.Inorganic dry powder painting can overcome above-mentioned deficiency.Lime and its derivative（Sierozem power, calcium hydroxide powder）It is about earliest
Inorganic dry powder painting, its film forming mechanism is the carbonization by lime, haves the shortcomings that ash is serious, has essentially dropped out application field.
In recent years under the urging of environmental requirement, occur in that inorganic dry powder painting develops upsurge, there is many documents and patent to disclose.Summarize
Come, developing inorganic dry powder painting substantially there are three class thin film-forming methods：1. using organic redisperse rubber powder as main film forming substance, such as
CN2009101933522.Such an approach achieves no longer carrying water or solvent, but for reduction VOC without too many constructive work
With；2. using the hydraulicity such as portland cement inorganic coagulation material as film forming matter, such as CN2013104093689.This method
Diamond Search can be realized while cost of transportation is saved, but hydrated cementitious, setting time are shorter, and coating must make immediately after mixing and stirring
With, it is impossible to place.3. film forming matter, such as CN2011104466990 are used as using alkali silicate and curing agent.This method
Principle is that alkali silicate forms indissoluble silicate colloid so as to film forming with curing agent chemically reactive, due in aqueous
The reaction speed of alkali silicate and curing agent is very fast, therefore thickening just occurs in work progress, and workability is poor.Such as
The slow coating of fruit speed of application even lumps failure.In addition to above-mentioned three basic forms of it, be more 1. with combination 2., 3.,
Such as CN2006100366259, CN2014108540807, CN2014108540760 etc..This combination reduces organic tree
Fat addition, the VOC of coating is also decreased, but can not be referred to as really purely inorganic coating, and its VOC value still relies on tree
The quality of fat.
