preparation example Construction

[0041] The preparation of UV-curable peelable blue glue composition comprises the following steps:

[0042] The UV-curable blue glue composition of the present invention can be prepared by putting each raw material of the adhesive composition into the mixing tank sequentially according to the proportioning requirements, and stirring according to a certain speed and time. The preparation process is carried out under normal temperature and pressure, and needs to be protected from light.

Embodiment 1

[0044] 1. Put 20g of aliphatic polyurethane acrylate oligomer DR-U315, 10g of hydroxyethyl acrylate, 40g of polyethylene glycol di(meth)acrylate (molecular weight 512) and 5g of sodium lauryl sulfate into the mixing tank Stirring in , the stirring speed was set at 1000rpm / min, and stirred for 20 minutes;

[0045] 2. Add 3g of 1-hydroxycyclohexyl phenyl ketone and 1g of 2,4,6-(trimethylbenzoyl) diphenylphosphine oxide, and 0.1g of 2,6-dibutyl-4- After methyl phenol is weighed, drop into stirring tank successively and stir, stirring speed is set as 1000rpm / min, and stirring time is 30 minutes;

[0046] 3. Filter and package the mixture in the mixing tank to obtain UV peelable adhesive with high toughness and high temperature resistance; the product performance test data are shown in Table 3.

Embodiment 2

[0048] 1. Put 25g aromatic polyurethane acrylate oligomer CN9782, 30g isocylacrylate, 20g amino-modified polyethylene glycol acrylate, 20g ethoxylated bisphenol A (meth)acrylate and 8g alkyl polyether After weighing, put it into the mixing tank and stir, the stirring speed was set at 900rpm / min, and stirred for 20 minutes;

[0049] 2. After weighing 4g of 1-hydroxycyclohexyl phenyl ketone, 1g of 2,4,6-(trimethylbenzoyl) diphenylphosphine oxide and 0.1g of tris(hexadecanyl alcohol) ester, Put it into the mixing tank and stir, the stirring speed is set to 1200rpm / min, and the stirring time is 40 minutes;

[0050] 3. Weigh 0.5g of blue pigment VP3491, 0.5g of dispersant BYK2008, and 0.2g of leveling agent, put them into the mixing tank, set the stirring speed at 1200rpm / min, and stir for 35 minutes;

[0051] 4. Filter and package the mixture in the mixing tank to obtain UV peelable adhesive with high toughness and high temperature resistance; the product performance test data ar...

Abstract

The invention relates to a high-toughness high-temperature-resistant UV peelable adhesive as well as a preparation method and an application thereof, which mainly solve the problems that in the priorart, an adhesive film of the UV peelable adhesive becomes hard and is not easy to peel off under a high-temperature condition. The raw material composition is prepared from the following components inpercentage by weight: 10 to 40 percent of urethane acrylate oligomer, 0 to 5 percent of multifunctional acrylate monomer, 10 to 30 percent of monofunctional acrylate monomer I with the molecular weight of less than 500, 18 to 51 percent of acrylate monomer II with the molecular weight of more than 500, 0.5 to 5 percent of a photoinitiator, 0.5 to 10 percent of a surfactant and 0 to 6 percent of an aid, the invention also provides the preparation method of the high-toughness high-temperature-resistant UV peelable adhesive. The UV peelable adhesive prepared by the method has the advantages of high temperature resistance, peelability, good toughness, good reliability and 100% solid content. The product can be applied to temporary protection of computer keyboard screw hole diameters, ITO filmcoating, temporary protection of mobile phone shells and provision of temporary protection in high-temperature operation or chemical corrosion operation.

Description

technical field [0001] The invention relates to a UV peelable adhesive with high toughness and high temperature resistance, a preparation method and application thereof. Background technique [0002] With the development of society, many industries need temporary protection of materials under the limitation of technology. In the case that a certain process may damage the material, use UV glue to stick it, remove it after sufficient protection, and then proceed to the next process. Due to different process operations, there are also various requirements for temporary protective colloids, such as high temperature resistance, corrosion resistance of various chemicals, CNC fine cutting resistance, and no falling off during high temperature and vibration generated by cutting. . Traditional UV peelable adhesives are formulated by selecting a resin with low adhesion to the substrate and combining some conventional monomers, such as isobornyl methacrylate or some monomers that do ...
