Abstract
The invention discloses a photocured adhesive for repairing micro cracks of automotive glass and a preparation method thereof. The preparation method mainly comprises: firstly, adding acrylic acid isobornyl ester, hydroxyethyl methacrylate and lauryl acrylate into a container and uniformly mixing the mixture; secondly, slowly adding pretreated nano silicon dioxide, stirring the mixture at the same time for preventing agglomeration till the nano silicon dioxide disperses completely and colorless transparent solution is formed; and finally, adding aliphatic polyester type polyurethane-acrylate, a pure acrylate oligomer, 2-hydroxy-2-methyl-1- phenyl-1-propyl ketone, 1-hydroxycyclohexyl phenyl ketone, 2,4,6-trimethyl benzoyldiphenyl phosphine oxide and 3-mercaptopropyl trimethoxysilane, and continuously stirring the mixture for 0.5 to 1 hour. The product of the invention is simple in use and high performance and tests show that the product of the invention has good repair effect on the micro cracks of the automotive glass.
Description
Technical field
The present invention relates to a kind of UV-light to visible light solidifying material, relate in particular to a kind of Photocurable adhesive that is applicable to vehicle glass fine crack Rapid-Repair and preparation method thereof.
Background technology
Along with rapid economic development, expect Chinese automobile output in 2010 and will reach 10,000,000, recoverable amount reaches 55,000,000, as the shatter proof glass of important subsidiary material, also will have a larger increase.In automobile use procedure, glass unavoidably can produce fine crack problem due to unexpected, affects attractive in appearance; If do not processed, along with time lengthening, due to reasons such as vibrations, crackle is expansion constantly, until break, affects security, and how economic, easy, this crackle of fast processing, prevents trouble before it happens, and is the problem that officer and car owner have to face.
Summary of the invention
The invention provides a kind of Photocurable adhesive of repairing for vehicle glass fine crack and preparation method thereof, this Photocurable adhesive is used simple fast, and repair efficiency is very good.
The present invention is achieved by the following technical solutions: a kind of Photocurable adhesive of repairing for vehicle glass fine crack, and its component and content are as follows:
Aliphatic polyester type polyurethane diacrylate 20-30%
Pure acrylic acid ester oligomer 10-20%
Isobornyl acrylate 20-30%
Hydroxyethyl methylacrylate 15-25%
Dodecylacrylate 20-30%
Pre-treatment nano silicon 1-5%
2-hydroxy-2-methyl-1-phenyl-1-propyl group ketone 1-5%
1-hydroxy cyclohexyl phenylketone 1-5%
TMDPO 0.5-2%
3-sulfydryl propyl trimethoxy silicane 1-2%.
Preferably, described pre-treatment nano silicon is, with γ-methacryloxypropyl trimethoxy silane, silicon-dioxide is carried out to surface grafting pre-treatment.
Preferably, the molecular weight of described aliphatic polyester type polyurethane diacrylate is 5000, and the molecular weight of described pure acrylic acid ester oligomer is 3000.
The present invention also provides the preparation method of this Photocurable adhesive, comprises the steps:
(1). first by isobornyl acrylate, hydroxyethyl methylacrylate, dodecylacrylate, add container to mix;
(2). secondly slowly add pre-treatment nano silicon, stir to prevent caking simultaneously, after disperseing completely, become colourless transparent liquid;
(3). then add aliphatic polyester type polyurethane diacrylate and pure acrylic acid ester oligomer, 2-hydroxy-2-methyl-1-phenyl-1-propyl group ketone, 1-hydroxy cyclohexyl phenylketone, 2; 4; 6-trimethylbenzoyl diphenyl phosphine oxide, 3-sulfydryl propyl trimethoxy silicane, continue stirring and within 0.5～1 hour, make described Photocurable adhesive.
After prepared by product of the present invention, after tested, automaobile glass repairing-mending has been reached to better effects.
Its advantage main manifestations is:
1, use simply, use simply, glue is splashed into cracks and get final product rapid permeability, Automated shade hair line.
2, solidify conveniently, with 100W, from ballast high voltage mercury lamp, press close to irradiate 30-50 second, or with solar radiation, also can meet the demands.
3, excellent property, water white transparency after repairing, crackle on glass disappears, and glued membrane is tough, water-tolerant, automobile continues, in use procedure, crack propagation phenomenon can not occur.
Photocurable adhesive of the present invention, various constituent materials convenient sources, preparation process is simple, has reduced the final product quality fluctuation that material slight error may cause.
