Description
Technical field
The invention belongs to paint field, be specifically related to a kind of ecological Degradable environment protection coating.
Background technology
Coating is lived closely bound up product as with people, is related to everyone physical and mental health, for coating the most all in contact.The murder by poisoning of coating is mainly manifested in: 1, glycol ether and esters solvent coating thereof directly have lethality effect to human body, if Long Term Contact, serious meeting causes blood, lymph impaired, and reproductive system is caused significant damage by more serious meeting.2, amino paint, abnormal smells from the patient is pungent, and the health hazard to human body is big；Should there be good ventilation equipment construction site, and painter should wear glasses, glove, mask etc., it is to avoid contact skin and suction coating cloud.No Open Flames in job site.3, major part anticorrosive paint can possess the coating that specific function, such as boats and ships use, and the noxious substance that need to add such as heavy metal class is used for killing Sargassum, and Long Term Contact is big to human health damage.4, the coating of band solvent toluene, irritant to skin, mucosa, central nervous system there is is anesthetic action；Environment there is is serious harm, air, water environment and water source can be polluted.
And 3-6 month after coating uses the most also is the period being easiest to be detrimental to health.VOC VOC, benzene, formaldehyde, heavy metal (lead, hydrargyrum etc.) etc. are mainly had according to the nuisance contained by expert introduction, coating and putty thereof；Wherein, benzene and benzene homologues are major pollutants.These VOCs reach certain peak value the burst size of 3-6 month, cause serious harm health.It is reported, benzene is defined as carcinogen by World Health Organization (WHO), can cause cancer, hematopathy etc..Expert reminds, and in addition to the pollution in construction is very important, the harm after moving in can not be despised.
Summary of the invention
Present invention aims to the deficiencies in the prior art, it is provided that a kind of ecological Degradable environment protection coating.This coating, by adding nanometer titanium dioxide, carbide, foaming agent, attapulgite and diatom ooze raw material, has reached quadruple ecology and has degraded effect, had environmental protection, the feature of safety.
For achieving the above object, the present invention adopts the following technical scheme that
A kind of ecological Degradable environment protection coating: be made up of by weight 5:1 first component and second component；
In parts by weight, first component consists of the following composition:
Resin 20-35wt%, reactive diluent
3-6wt%, carbide 12-15wt%, nanometer titanium dioxide 10-15wt%, attapulgite 10-16wt%, diatom ooze 12-20wt%, auxiliary agent 0.75-2.2wt%, pigment 4-15wt%, above each composition quality mark sum is 100%；
In parts by weight, second component consists of the following composition:
Firming agent 99.3-99.7wt%, foaming agent 0.3-0.7wt%, above each composition quality mark sum is 100%.
Described auxiliary agent includes one or more in dispersant, levelling agent, catalyst and initiator.
Described pigment includes that phthalein is Dracocephalum moldabium, one or more in carbon black, benzidine yellow and iron oxide red.
Described resin be polydimethylsiloxane, polysulfide modified epoxy resin and acrylic resin modified in one or more.
Described firming agent is modified amine curing agent.
Described foaming agent is the one in azodicarbonamide and anilinoazobenzene.
The quadruple of present invention effect of degrading is:
1) the first weight, adds foaming agent in coating and coating can be made to produce substantial amounts of micropore, can adsorb the steam in air, and such nanopores is just filled with substantial amounts of steam；The carbide added in coating reacts with water, produces substantial amounts of negative oxygen ion, it is possible to the harmful substance in substantial amounts of absorption air；
2) the second weight, diatom ooze is nano level porous material (micro-pore diameter about 0.1-0.2 micron), and porosity is up to 90%, rule, is fitly arranged in circle and aciculiform, and the minute aperture quantity in its unit are goes out thousands of times more than Linesless charcoal；Prominent molecular lattice structure feature, determines the function of its uniqueness；Diatom mineral have extremely strong physical absorption performance and ion-exchange performance, it is possible to the harmful substance in absorption air, the effect play and purify air, eliminating abnormal flavour；
3) the triple, and Attapulgite clay is soil block structure, light specific gravity, mohs hardness 2-3 level, tacky and plasticity time moist, dry shrinkage is little, and does not produce be full of cracks, and water absorption is strong, can reach more than 150%, about pH=8.5, due to internal porous road, specific surface area is big, up to 350m2/ more than G, most cation, hydrone and a certain size organic molecule all can directly be adsorbed in inlet hole road, and its stable electrochemical property；Owing to they have the biggest specific surface area and certain ion exchangeable, it is possible to effectively adsorb the harmful substance in air, reach the effect of ecological degraded；
4) quadruple, nanometer titanium dioxide is white powder, and particle diameter is little, has good photocatalysis characteristic, and its photocatalysis rate is far above common titanium dioxide, and nano titanium oxide (TTP-A10) granule is decreased to nanoscale, is greatly improved photocatalysis rate.Under the irradiation of ultraviolet light, nano titanium oxide valence-band electrons is excited to conduction band, the O defining electronics and hole with being adsorbed in its surface2And H2O effect, can generate the hydroxyl radical free radical that oxidisability is extremely strong；These free radicals can oxidative degradation Organic substance so that it is be converted into CO2、H2O and inorganic matter, degradation speed is fast, non-secondary pollution.
Compared with prior art, present invention have the advantage that
1) present invention compounds by the weight of these five kinds of raw materials of nanometer titanium dioxide, carbide, foaming agent, attapulgite and diatom ooze carries out science so that the ecological degradation effect of coating reaches splendid state, and raw material totle drilling cost reaches minimum；
2) easy construction, safety, scrubbing resistance, good permeability, also has good decorative effect simultaneously；
3) can degrade the harmful substance (formaldehyde, sulfur dioxide) in air, purify air, eliminate abnormal flavour；
4) low-carbon environment-friendly, does not results in the pollution of surrounding.
Detailed description of the invention
For the openest rather than restriction present invention, below in conjunction with example, the present invention is described in further detail.
