Problems solved by technology
In the prior art, the film-forming properties of this type of spray after spraying are mostly similar to paint-like coatings, that is, they cannot be removed directly and quickly after film formation, and need to be removed by using other cleaning agents or by scraping, which is not only troublesome to operate And it is easy to damage the surface of the decoration
If direct superimposition is used to spray again to change the object to be decorated, it is difficult to achieve the expected spraying effect due to the existence of the background color
In addition, the weather resistance and corrosion resistance of the existing coating film formed by this type of spray are poor, and the service life is short

Embodiment Construction
[0026] The present invention will be further described below in conjunction with specific examples.
[0027] Raw materials are weighed according to the weight percentage content of components: fluorine rubber powder 30%-35%, polyester resin 25%-30%, color masterbatch 3%-5%, dilution solvent 20%-25%, LPG propellant 10% -15%.
[0028] The fluororubber powder described therein has a CAS number of 9002-84-0 and a molecular structure of (C 2 f 4 ) n of fluororubber powder. Described polyester resin is specifically that CAS number is 25135-73-3, molecular formula is (C 10 h 10 o 4 ·C 10 h 10 o 4 ·C 2 h 6 o 2 ) x of polyester resin. The color masterbatch specifically has a CAS number of 3905-19-9 and a molecular formula of C 40 h 24 CL 4 N 6 o 4 , the masterbatch. The diluting solvent is specifically CAS No. 123-92-2, molecular formula C 7 h 14 o 2 , the dilution solvent. The LPG propellant specifically has a CAS number of 68476-85-7 and a molecular formula of...

The invention relates to a spraying agent capable of stripping a protective coating film and a production process of the spraying agent. The spraying agent comprises the following components in percentage by weight: 30%-35% of fluorine rubber powder, 25%-30% of polyester resin, 3%-5% of color masterbatch, 20%-25% of diluting solvents and 10%-15% of LPG (Liquefied Petroleum Gas) propellants. The spraying agent capable of stripping the protective coating film can be sprayed on the surfaces of any objects and can be deformed to form a rubber layer protective film after tens of seconds, and the rubber layer protective film has strippability and can be directly stripped without any residues after stripping, and thus a user can fast spray to obtain a required decorative effect as required. The spraying agent capable of stripping the protective coating film, which is disclosed by the invention, has the advantages of good physical resistance and chemical resistance on film forming, water prevention, oil prevention, scratching prevention, bump prevention, acid rain prevention, dust prevention, fingerprint prevention, acid-base corrosion resistance and high-low temperature resistance. According to the spraying agent, the protective film can be integrally torn and stripped without damaging a substrate or leaving a trace.
Description
Technical field: [0001] The invention belongs to the technical field of coatings, and relates to a spray-type film-forming spray, in particular to a peelable protective coating film spray and a production process thereof. Background technique: [0002] In industries such as construction and home decoration, car decoration products, and decoration, spray sprays are often used to change the color and pattern of the decorated objects. After the spray spray is sprayed on the surface of the object, one or more layers of paint film are formed. In the prior art, the film-forming properties of this type of spray after spraying are mostly similar to paint-like coatings, that is, they cannot be removed directly and quickly after film formation, and need to be removed by using other cleaning agents or by scraping, which is not only troublesome to operate And it is easy to damage the surface of the decorated object. If the object to be decorated is changed by spraying again by direct ...
