Abstract
The invention relates to a casing and a manufacturing method thereof, belongs to the field of painting of plastic cement products, and particularly relates to a manufacturing method of plastic cement products using a static electricity powder painting technique.
Description
Technical field
The present invention relates to plastic cement products and preparation method thereof, relate to plastic cement products field of coating, especially design the preparation method that plastic cement products uses electrostatic powder body coating technology.
Background technology
Nylon as most important kind maximum in engineering plastics, especially its modified characteristic realizing high performance, PA adds the glass fibre of 30%, the mechanical property of PA, dimensional stability, thermostability, ageing-resistant performance have and clearly improve." to mould Dai Gang, performance brilliance ", purposes is extremely extensive.It has lightweight, intensity is high, self-lubricating, wear-resisting, anticorrosion, the multiple special performance such as insulation.It is widely used engineering plastics, almost spreads over all of industrial circle.But it is single that nylon adds glass material color after molding, but surface physical properties is poor, polarity is low, in spraying coating process, the basic demand of performance is adhesive force one just more difficult control only.Being only capable of realizing pretreating reagent at present and add organic coatings volatile organic compounds, pollute big, efficiency is low.And powder coating is a kind of new technique at environment-protecting asepsis, gather efficient, energy-conservation, the saving advantage such as cost, environmental protection, powder coating is from being worked into finished product almost without the harmful substance such as formaldehyde and VOC, production is not necessary to unnecessary blowdown cost and environmental protection cost, and low-temperature setting powder body is the emphasis direction researched and developed in the industry.
Summary of the invention
The present invention provides a kind of housing and manufacture method thereof, and this housing utilizes nylon to add glass injection mo(u)lding, re-uses powder coating spraying, and technique is simple, and environmental protection.
The present invention provides the special Preparation Method of a kind of housing, including:
Powder body priming paint is formed on plastic rubber substrate surface；
Powder body finish paint is formed at described powder body primed surface.
Saying further, described preparation method also includes: before plastic rubber substrate surface forms powder body priming paint, preheat 3 ~ 5 minutes, and preheating temperature is 85 ~ 95 DEG C；
Saying further, described preparation method also includes: also include: before described powder body primed surface forms powder body finish paint, need to through hot setting, and solidification temperature must at 120 DEG C-140 DEG C；
Saying further, described preparation method also includes: also include: after described powder body finish paint is formed, need to through hot setting, and solidification temperature must at 110 DEG C-130 DEG C；
Saying further, described plastic rubber substrate is added glass by nylon and forms, and ratio is: nylon 65%-75%, glass 25%-35%.
Saying further, described plastic rubber substrate also includes auxiliary agent, including high molecular polymer.
Saying further, described powder body includes low-temperature resins, epoxy resin, firming agent, infrared ray initiator, adjuvant, pigment, and ratio is: 45%-68%, 5%-8%, 3%-15%, 3%-7%, 1%-5%, 8%-23%.
The present invention also provides for a kind of housing, including: plastic rubber substrate, the powder body priming paint being successively set on plastic rubber substrate and powder body finish paint.
Innovative point of the present invention is in that: 1, plastic rubber substrate is to be added glass by nylon to add the making of high molecular polymer auxiliary agent again, improves product surface physical property, improves its mobility and flame resistance.2, the component for powder body improves so that it is just can be successful curing at about 120 DEG C.And temperature required when generally powder coating is by electrostatic painting process formation coating is 180 DEG C-200 DEG C, but plastic cement can deform again at this temperature, forms contradiction.The invention solves this contradiction.It is an advantage of the current invention that: 1. environmental protection completely, reach more than 95% response rate, without pollution problems such as waste water；2. equipment unification, it is simple to volume production；3. processing heavy industry is easy, and raw material scraps reduction；4. getting the raw materials ready simple, handling of goods and materials is concentrated.
