A Production Method Of Stone Paint Made By Granite Cutting Waste Materials Of Dawu Country

There is evitable produce a lot of waste rock slag by the processing of stone,by stockpiling rock slag waste of resources and land,so recycling waste stone is more and more concerned.This article mainly discusses about the production method of stone paint made by granite cutting waste materials of Dawu country.Stone paint is a kind of composite dispersion suspended coating.It comprises of different colors,size and shape of the granular which are incompatible with dispersed medium.It usually contains two or more of the color particles,and can form a variety of color patterns.In this paper,according to the basic formula and production method of the stone paint,respectively to examine the optimum ratio of the gelling agent and the crosslinking agent in the stone paint,ratio of stone waste and quartz sand in colored particle system.The effect of various additives on the performance of the stone paint was tested.In addition,the synergistic effect of different crosslinking agents was also analyzed.In the end,studying the effect of production method on stability,and the stone paint which can meet the requirements was prepared.By using the basic formula of the stone paint as the experimental base,choose crosslinking agent and gelling agent of the experiment,inorganic salt as crosslinking agent,cellulose ether as gelling agent.The best ratio of crosslinking agent and sizing agent is 2.5: 2.2,the ratio of stone waste and color quartz sand is 4: 1.In the time the additives in the stone paint have certain influence on the performance of the coating,the best dosage of emulsion is 25% of the quality of the stone paint,the defoamer is 0.5%,the tackifier is 0.3% of the stone coating system,and the bentonite solution is 1.5%.In 200 g stone paint,the quality of the crosslinking agent was 2.5g,the flocculant of Fe Cl3 and Al Cl3 as 1: 4 was used as the crosslinking agent in the stone paint.The synergistic effect of blending flocculant can enhance the protective effect of the colored particles,to solve the alkali resistance of stone coating problem,and solve the problem ofFe Cl3 dyeing.The best production method of stone paint is mixing time 60 seconds and shear rate550 revolutions per minute.The high shear rate and mixing time will cause the additives in the coating system to be distributed,which leads to the decrease of the stability of the stone paint,on the contrary,the dispersion of colored particles is not uniform.The stain resistance of stone paint is the best use of dilution ratio of 1: 2 ludox A.That the imitation stone paint coating according to the national standard routine performance testing can achieve the quality indicators.
