Abstract
The invention relates to the technical field of plastic products and discloses a plastic surface hardening treatment method.The method includes steps: cleaning a to-be-treated plastic part in deionized water at 50-60 DEG C for 15-20min, spraying and drying; filtering photocuring paint through a 600-1200-mesh screen, performing infrared drying for 20-25min at 60-65 DEG C, and performing cooling and leveling for 1-3min at the room temperature, wherein a spray coating pressure is 32-38kg/cm<2>; subjecting a formed coating to ultraviolet curing for 1-3min at 40-50 DEG C.By the plastic surface hardening treatment method, the problems of high cost and high paint waste in existing plastic surface hardening are solved.
Description
Technical field
The present invention relates to plastic products technology field, the hardening process of especially a kind of frosting.
Background technology
Plastics because of its light weight, will not the excellent performance such as corrosion, shock-resistant, easy processing, and be widely used in producing or in the articles for daily use.But; plastics are compared to metal; its case hardness is relatively low; surface is easily subject to damage, especially as the working of plastics of the electronic product display screen such as mobile phone, camera or lens etc., if its case hardness is relatively low; after long-term use; plastic part surface easily scratches, scratches, and has a strong impact on visual effect and surface optical performance, thus this kind of plastic plate would generally be carried out Surface hardening treatment.Existing frosting cure process mainly has two kinds of technology, one is to soak plastics with chemical agent and dry hardening, another kind is to spray hardened layer at frosting, there is poisonous and harmful substance in former, it is unfavorable for environmental protection, the hardening mode that the latter UV of employing solidifies more, but its problem that to there is paint waste more, relatively costly.
Summary of the invention
It is an object of the invention to provide the hardening process of a kind of frosting, this method can solve the hardening of existing frosting and there is the problem that paint waste is more and cost is high.
In order to solve the problems referred to above, the technical solution used in the present invention is: the hardening process of this frosting comprises the following steps:
A, pending working of plastics is put in the deionized water that water temperature is 50～60 DEG C cleaning 15～20min, after spray, be dried；
B, with 600～1200 order net filtration photocuring paint vehicles, spray pressure 32～38kg/cm2, use infrared drying 20～25min when 60～65 DEG C, under room temperature, cool down levelling 1～3min；
C, with the ultraviolet light polymerization step B film formed, solidification temperature is 40～50 DEG C, and the time is 1～3min.
In the technical scheme of the hardening process of above-mentioned frosting, technical scheme is it may also is that the spray temperature of step B is 40～45 DEG C more specifically, dry and carry out at twice, first time baking temperature 58～62 DEG C, dry 5～8min, at room temperature dries 5～10min, carries out second time dry, baking temperature 62～65 DEG C, dry 3～5min.
Further, the wavelength of the ultraviolet light in step C is 260～272nm.
Owing to have employed technique scheme, the present invention compared with prior art has the advantages that the hardness improving frosting, coating hardness can reach 6H, so that its surface is more resistant to delineation and scraping, having good optics anti-scratch performance, coating surface performance is good, without doing over again, save coating consumption, and without expensive equipment, reduce production cost.
Detailed description of the invention
Below in conjunction with embodiment, the invention will be further described:
