Agent of car engine route protection and method of manufacture thereof
Technical field
The present invention relates to a kind of film-formable route protection agent, specifically relate to a kind of can be at the film forming aerosol-type protective material of car engine outside line.
Background technology
According to the statistics made by the departments concerned, Chinese automobile production and marketing in 2009 surpasses 1,350 ten thousand, becomes world car production and marketing first big country first.The fast development of developing of automobile industry, especially private car is for Chinese Economy Development has been made significant contribution.But, meanwhile also bring many negative issues, in recent years, the declaration of an accident that self-burning of vehicle is constantly arranged in all parts of the country, national self-burning of vehicle accident rises at double in 1 year according to statistics, nearly surplus in the of 8000, causes the several hundred million units of direct economic loss.
Be the season that motor-vehicle accident takes place frequently summer, the circuit easy ageing under long-time high temperature in automobile engine nacelle of gathering, and be full of cracks causes electric leakage, and terminal comes in contact bad because of jolting for a long time, be prone to produce electrical spark, can cause engine auto-ignition in the time of seriously.Therefore it is very important to let automobile ride out in the summer that The sun is shining fiercely, and the maintenance of automobile engine nacelle internal circuit is very urgent.
The patent of protection engine circuit is still few at present; Application number is that the patent of CN200710134542.8 has been mentioned a kind of method of making the agent of engine route protection; Wherein with resol or Synolac as filmogen; The resol here is the relatively poor resin of a kind of weathering resistance, winter the cold north very easily ftracture and come off.Synolac is not acid and alkali-resistance and hydrolysis then, all can cause guard time not long, thus impact effect.What the present invention adopted is the more excellent resin of a kind of weathering resistance, acid and alkali-resistance, hydrolysis, does not after-tack during the broiling summer after the use, and do not ftracture cold winter; Protect engine circuit on every side throughout the year for a long time; Delay aging circuit, the prevention line short prevents self-burning of vehicle.
Summary of the invention
The object of the present invention is to provide the method for manufacture of a kind of car engine route protection agent; The engine route protection agent of the application of the invention; On the car engine outside line, form one deck insulation, acid and alkali-resistance, water-fast, bright protective membrane; Can delay aging circuit, the prevention line short prevents self-burning of vehicle and can make nacelle light as new.
The present invention realizes that the technical scheme that goal of the invention is taked is:
Car engine route protection of the present invention agent comprises following component: polar solvent, insulating resin, wetting agent, flow agent, fire retardant, deodorization LPG liquefied petroleum gas.The mass percent of each component is:
Polar solvent 30-60%
Insulating resin 10-40%
Wetting agent 0.1%-1%
Flow agent 0.1%-1%
Fire retardant 1%-3%
Deodorization LPG liquefied petroleum gas 20%-40%
Described polar solvent can be a kind of in butyl glycol ether, N-BUTYL ACETATE, ritalin, acetone, ethanol, the methyl alcohol or several.
Described insulating resin can be a kind of in modified alkyd resin, vinyl resin, urethane resin, the polymeric amide or several mixture.
Described wetting agent is non-ionics or polyether-modified polysiloxane-based wetting agent.
Described flow agent is BYK-310 or HX-3310.
Described fire retardant is halogenated flame retardant or phosphorus flame retardant.
Car engine route protection of the present invention agent can be used for car engine outside line such as hi-line, line node, pile head of storage battery etc.It has following characteristics:
1. insulativity is strong, voltage breakdown 20KV/mm, surface resistivity 3 * 10
12Ω.
2. persistence is good, and high temperature is not clamminess after the film forming, and low temperature does not ftracture, do not come off, and protects rubber parts lastingly.
3. good flame resistance is not burnt after film forming is dried, has anti-flaming function.
4. prevent aging circuit, online road surfaces forms one deck compact protective film, well stops or has delayed because of aging to the circuit rubber parts of long term high temperature in the nacelle.
5. remove the circuit greasy dirt, contained solvent can effectively be removed the various greasy dirts on the circuit in the prescription.
6. make light as new in the nacelle, have good gloss after the film forming, can let the lasting light that keeps as the new car in the nacelle.
7. the dirt that bears dirty, surface energy is low, and fouls such as greasy dirt, sewage are difficult for adhering to, and remove easily.
The practical implementation method
For better implement the present invention, lift following instance explanation, but embodiment not a limitation of the present invention at present.
Embodiment 1
The agent of a kind of car engine route protection, each constituent mass per-cent is following:
Vinyl acetic monomer 40%
Insulating resin 30%
Wetting agent 0.5%
BYK-310 0.5%
Fire retardant 3%
Deodorization LPG liquefied petroleum gas 26%
The practical implementation method is: at first insulating resin is dissolved in the vinyl acetic monomer at normal temperatures, adds wetting agent, BYK-310, fire retardant then successively and mix, in the aerosol jar of packing into, charge into the deodorization LPG liquefied petroleum gas at last.Promptly get product of the present invention.
