Embodiment
The feature of the present invention and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so that the understanding of technician of the same trade:
What following examples related to is the coating with composite material resin circular fiber power, the component of this coating is paint vehicle, filler, pigment, solvent, auxiliary agent and water, wherein filler adopts resin circular fiber power, the weight percent of above-mentioned each component is: the content of paint vehicle is 30%～45%, the content of filler (resin circular fiber power) is 20%～40%(preferable range is 25%-35%), the content ratio of pigment, solvent, auxiliary agent is determined according to coating applications, and foot portions is not supplied by water.
Paint vehicle is the important component in coating, determines the selected of paint vehicle according to different coating article.
Filler component in coating is except can increasing the volume of goods in coating, filling effect can also be played and reduce the effect of coating cost, at present, the filler (also known as pigment extender) comparatively commonly used at coating mainly contains natural pigment extender and synthetic pigment extender two kinds, as shown in table 1 below, these conventional fillers are very limited for the lifting of coating property, and cost is higher.
Table 1
| Classes of compounds | Natural pigment extender | Synthesis pigment extender |
| Oxide compound and oxyhydroxide | Aluminum oxide, magnesium oxide etc. | Aluminium hydroxide, magnesium hydroxide |
| Silicon-dioxide and silicate | Quartz sand, diatomite, talcum powder, kaolin, mica etc. | Calcined silica, precipitated silica, ca aluminosilicate etc. |
| Carbonate | Calcite, chalk, rhombspar, wagnerite etc. | Precipitated chalk etc. |
| Vitriol | Barite, gypsum etc. | Process white etc. |
| Other pigment extenders | Dust cork, rock wool etc. | Granulated glass sphere, glass fibre, polymer fiber etc. |
And following examples have employed resin circular fiber power and carry out the conventional fillers in substitution tables 1, this resin circular fiber power filler is substantially the mixture of epoxy resin and glass fibre, so having the hydrophilicity of silicon oxide etc., as the filler composition of coating, this hydrophilicity is extremely important, because there being this characteristic in the production process of coating, filler just has the effect of well moistening, depolymerization, stabilization;Therefore, with composite material resin circular fiber power as filler, from making to storage, and final this serial procedures of film forming ensures that it is in good dispersion state all the time, and the coating of ratio conventional filler composition making has more erosion resistance and oxidation-resistance.
As shown in Figure 1, resin circular fiber power derives from Waste appliances, the method extracted is as follows: disassembled by waste household appliances, pick out waste electron wiring board wherein, useless time copperclad plate and scrap stock, by carrying out mill powder after its fragmentation, it is crushed to granularity and it is not less than 80 object pellets, afterwards by these pellets through air and electrostatic separation, extracting metallic copper fine powder, residue pellet is resin circular fiber power; The resin circular fiber power of gained being carried out fine powder broken, for guaranteeing the purity of resin circular fiber power, the resin circular fiber power after fine powder is broken, again through air and electrostatic separation, extracts metallic copper fine powder, and remaining is resin circular fiber power; The water ratio of resin circular fiber power is not more than 6%, make it again through drying facility, control its water ratio and it is less than 2%, then by screen cloth, resin circular fiber power is divided into-80 orders, 80-100 order ,-100 object pellets with wind-force machine, use to be respectively used to the filler as different coating article, such as waterproof paint, emulsion paint or building coating. The regeneration of this composite material resin circular fiber power solves current generally thinks that it can not be recycled and is therefore caused the serious problems of environmental pollution by arbitrarily abandoning both at home and abroad.
The production technological process being illustrated in figure 2 this coating article, specifically comprises the steps:
1) the resin circular fiber power pellet of desired particle size size (-80 orders, 80-100 order ,-100 orders) is chosen;
2) resin circular fiber power and a certain proportion of paint vehicle, solvent, auxiliary agent are inserted ball mill or sand mill carries out reinforced mixing, carry out coarse filtration afterwards, carry out grinding distribution again after coarse filtration and high-speed stirring mixes, make grinding mill base;
3) this grinding mill base Cemented filling or movable receptacle are transported two kinds of mode input paint mixing tanks and carries out paint by pigment and water, then after finly filtration, obtain coating article, finally carry out packing, check and putting in storage, complete whole technological process.
As previously mentioned, composite material resin circular fiber power is the complex body of epoxy resin and glass fibre, its physics and chemistry stable in properties, so as filler in coating article is produced, its advantage has be it to ph stability at three: one, not containing soluble substance, therefore do not damage the globality of coating, the infiltration of coating can not be caused and affect its barrier propterty; Two is that it has fiber and fibrous particle shape, therefore can play the effect increasing strength of coating and cracking resistance line, it is to increase the tensile strength of paint film; Three is it is the recycling of resource, as filler, it greatly increases the volume of coating, and the production cost reducing coating bigger therefrom, improves the economic target of enterprise.
