Abstract
The invention relates to a water-based environmentally-friendly latex paint for interior walls, which comprises the following components in percentage by weight: 20-30% of water, 0.8-2% of dispersant, 0.2-3% of thickening agent, 0.2-1% of wetting agent, 0.2-0.8% of defoamer, 35-40% of pigment, 30-40% of film forming matter, 0.15-0.2% of pH value regulator and 0.02-0.05% of sterilization mildewcide. The invention is free of APEO, contains ultralow content of VOC, and is innoxious and harmless, thereby being a water-based environmentally-friendly latex paint for interior walls, which meets the strict environmental requirements indeed.
Description
Technical field
The present invention relates to a kind of inner wall of building coating, be specifically related to a kind of water-based environmentally-friendly latex paint for interior walls.
Background technology
The purifying ecological environment prevents the infringement of obnoxious flavour, is protection human survival and healthy fundamental prerequisite.But the deterioration of living environment, the generation of a large amount of obnoxious flavoures, people's healthy and quality of life in serious threat.Along with improving constantly of people's living standard, " green consumption " is rooted in the hearts of the people.Aspect domestic environment, people no longer only pay attention to attractive in appearance and fashion, more emphasize health environment-friendly.Along with the growing interest of people to environment protection and self health, home environment healthization has become development today trend.
There is the building coating manufacture that exceedes 5,000,000 tons every year in China, and country has put into effect the content of solvent and soluble heavy metal in the multinomial limits of harmful substances standard coating products such as GB18581 successively at the building decoration articles for use relevant conscientiously with the people's livelihood.The environmental protection bull's eye sign authentication of China has also proposed strict restriction to volatile organic matter VOC.
APEO (polyoxyethylene nonylphenol ether compounds) and VOC are familiar with by people day by day to the hazardness of human and environment, and be subjected to paying attention to widely, as comprising among the APEO that polyoxyethylene nonylphenol ether (NPEO) accounts for 80-85%, polyoxyethylene octylphenol ether (OPEO) accounts for more than 15%, and dodecyl phenol polyethenoxy ether (DPEO) and binonylphenol Soxylat A 25-7 (DNPEO) respectively account for 1%.World's alkylphenol polyoxyethylene (APEO) yearly consumption is 8.8 hundred million pounds, wherein is polyoxyethylene nonylphenol ether (NPEO) more than 80%.Because APEO endangers by extensive studies and demonstration the environment potential.
APEO contains carcinogenic substance NPEO9-10, the toxicity of NPEO9-10: LD50=1600mg/Kg; ECO50 to water flea is 42mg/L; ECO50 to algae is 50mg/L, shows NPEO to Mammals and hydrobiological toxicity and carcinogenic, and is simultaneously similar to other non-ionic surfactants.Biological degradation rate is 0%-9% only, and degradation property is slow; Simultaneously, it also has similar female hormone effect, and the normal hormone secretion of harmful to human causes human body to produce " female effect " and distortion, severe impairment human reproductive system.Different policies has been taked to APEO in countries in the world at present, and U.S., Australia and some developing countries are still producing and using APEO.A lot of countries are also arranged, comprise that Britain, Germany, Switzerland, Denmark and Japan etc. have all formulated the rules that restriction APEO produces and uses in succession.European Union completely forbids the product that use contains APEO after being specified on January in 2005 17.Believe in the near future, have the ranks that more country (comprising China) adds European Union, completely forbid coating industry and use the product that contains APEO.In the face of the forbidding of APEO, at first we should be paid attention to, and adopt some effective means then to stop to produce and use the auxiliary agent that contains APEO, and the key that addresses this problem is to seek suitable tensio-active agent effectively to substitute APEO.
Tradition filmogen such as pure-acrylic emulsion, benzene emulsion etc. must add tensio-active agent such as APEO and serve as the emulsifying agent of stabilising system, and also can use APEO class tensio-active agent for the emulsification hydrophobic granule in conventional adjuvants such as the defoamer in synthetic.
We must face except APEO (polyoxyethylene nonylphenol ether compounds), because most of aqueous latex paint adds the various auxiliary agents that contain volatile organic matter compound (VOC) in process of production, after application since volatilization also can cause infringement to health of human body.Experiment shows, when the VOC in the room reached finite concentration, people can feel headache, feel sick, vomiting, weak etc., can have a convulsion, go into a coma when serious, and can hurt people's liver, kidney, brain and neural system, cause serious consequences such as hypomnesis.Therefore, American-European countries has all worked out strict standard to the VOC content in the emulsion paint.It reduced to 75g/L the U.S.'s 1113 rules and regulations building flat paint in 2007, reduced to 30g/L to 2011, the Chinese government has has also formulateeed and implemented comparatively strict limit standard in 2008, " limits of harmful substances in the indoor decorating material interior wall coating " regulation always must not surpass 120g/L, and the aqueous inner wall paint environmental labelling product authentication requesting specified standards of the up-to-date issue of State Environmental Protection Administration is≤80g/L.Therefore, how to reduce the problem that objectionable impuritiess such as the VOC of coating and APEO, development environment-friendly type " green coating " have become domestic coatings industry growing interest as far as possible.
Summary of the invention:
The purpose of this invention is to provide a kind of water-based environmentally-friendly latex paint for interior walls, it does not contain APEO, its VOC content approaches zero, has reduced the harm to environment and human body.
The object of the present invention is achieved like this: a kind of water-based environmentally-friendly latex paint for interior walls, and this water-based environmentally-friendly latex paint for interior walls component and content (percentage meter by weight) are as follows:
