Embodiment
Feature of the present invention and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so that technician's of the same trade understanding:
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 that 20%～40%(preferable range is 25%-35%), the content ratio of pigment, solvent, auxiliary agent is determined according to coating purposes, and insufficient section is supplied by water.
Paint vehicle is the important component in coating, determines the selected of paint vehicle according to different coating articles.
Filler component in coating is except can increasing the volume of goods in coating, can also play the effect of filling effect and reduction coating cost, at present, the filler (claiming again pigment extender) of comparatively commonly using at coating mainly contains two kinds of natural extender and synthetic pigment extenders, 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 extender | Synthetic 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 in following examples, adopted resin circular fiber power to carry out the conventional fillers in substitution tables 1, this resin circular fiber power filler is in fact the mixture of epoxy resin and glass fibre, so there is the hydrophilicity of silicon oxide etc., as the filler composition of coating, this hydrophilicity is extremely important, because there has been this characteristic in the production process of coating, filler just has the effect of well moistening, depolymerization, stabilization; Therefore,, storing from making extremely, and ensureing that it is all the time in good dispersion state in final these a series of processes of film forming as filler with composite material resin circular fiber power, and than having more erosion resistance and oxidation-resistance with the coating that conventional filler composition is made.
As shown in Figure 1, resin circular fiber power derives from useless household electrical appliances, the method of extracting is as follows: waste household appliances is disassembled, pick out waste electron wiring board wherein, useless time copperclad plate and scrap stock, to after its fragmentation, carry out abrasive dust, be crushed to granularity and be not less than 80 object pellets, afterwards by these pellets process air and electrostatic separation, extract metallic copper fine powder, residue pellet is resin circular fiber power; The resin circular fiber power of gained is carried out to fine powder broken, for guaranteeing the purity of resin circular fiber power, the resin circular fiber power after fine powder is broken passes through air and electrostatic separation again, extracts metallic copper fine powder, the remaining resin circular fiber power that is; The water ratio of resin circular fiber power is not more than 6%, make it pass through again drying facility, control its water ratio and be less than 2%, then resin circular fiber power is divided into-80 orders, 80-100 order ,-100 object pellets with wind energy conversion system by screen cloth, use as the filler of different coating articles being respectively used to, as waterproof paint, emulsion paint or building coating.The regeneration of this composite material resin circular fiber power has solved Present Domestic and has generally believed that it can not recycle and therefore arbitrarily abandoned and cause the serious problems of environmental pollution outward.
The production technological process that is illustrated in figure 2 this coating article, specifically comprises the steps:
