Problems solved by technology

But its disadvantages are: 1) Slow drying; 2) It needs to be baked for a long time above 170°C to cure; 3) It needs strong solvents, such as ketone solvents, to dissolve, and the solubility of solvents is relatively high.
However, because the main resin is alkyd, the corrosion resistance is poor, and there are many problems such as poor performance in damp heat resistance, CASS resistance and water softening.

Embodiment 1

[0053] Embodiment 1 prepares acrylic acid-epoxy ester hybrid resin

[0054] Step 1: Preparation of epoxy ester: As shown in the formula in Table 1, put epoxy resin E-12, soybean oil acid, linolenic acid and zinc oxide into the reaction kettle, add 80kg of refluxing xylene, heat up to 150°C-160°C and then click When the motor is normal, start stirring. When the temperature is 180°C-200°C, keep warm for 4 hours and start to detect the acid value and viscosity. When the acid value is about 6mgKOH / g, it is the end of the reaction. While cooling, dilute with xylene until the solid content is (50±1)%, and at the same time control the viscosity to be around 120s (coat four cups, 25°C), filter and discharge for later use;

[0055] Step 2: Preparation of acrylic acid-epoxy hybrid resin: formula as shown in Table 1, 1000kg epoxy ester, take 16kg AIBN and mix evenly with the acrylic monomer in the formula, then take 250kg of mixed monomer and put it into the reaction kettle to make a pri...

Embodiment 2

[0056] Embodiment 2 prepares acrylic acid-epoxy ester hybrid resin

[0057] Step 1: Preparation of epoxy ester: as shown in the formula in Table 2, put epoxy resin E-12, soybean oil acid, oleic acid, linolenic acid and zinc oxide into the reaction kettle, add 84kg of reflux xylene, and heat up to 180°C-200°C Keep warm at ℃ for 4 hours and start to detect the acid value and viscosity. When the acid value is about 7mgKOH / g, it is the end of the reaction. Put the material into the dilution kettle, and dilute it with xylene while cooling until the solid content is (50±1)%. Adjust the viscosity for about 150s and set aside;

[0058] Step 2: Preparation of acrylic acid-epoxy hybrid resin: According to the formula in Table 2, put 2000kg of epoxy ester into the reaction kettle and raise the temperature. Take 18kg of BPO and acrylic acid monomer and mix evenly, then take 200kg of mixed monomer and put it into the reactor as a primer, raise the temperature to 98°C and start to keep war...

Embodiment 3

[0063] Embodiment 3 prepares acrylic acid-epoxy ester hybrid resin

[0064] Step 1: Preparation of epoxy ester: as shown in the formula in Table 3, put epoxy resin E-12, dehydrated ricinoleic acid, linolenic acid and lead oxide into the reaction kettle, add 60kg of reflux xylene, heat up to 180°C-200°C and keep warm Start to check the acid value and viscosity after 4 hours, when the acid value is about 5mgKOH / g, it is the end of the reaction, put the material into the diluting kettle, dilute with xylene while cooling until the solid content is (50±1)%, adjust the viscosity About 110s, spare;

[0065] Step 2: Preparation of acrylic acid-epoxy ester hybrid resin: as shown in Table 3, mix 1500 kg of epoxy ester, 12 kg of tert-butyl benzoyl peroxide and acrylic acid monomer, and then put kg of mixed monomer into the reactor Make a base in the middle, raise the temperature to 130°C and start keeping warm, control the holding temperature at 130°C-135°C for 30 minutes, drop the rema...

Abstract

The invention provides an acrylic acid-epoxy ester hybrid resin. The acrylic acid-epoxy ester hybrid resin is prepared by reacting an epoxy resin and aliphatic acid under the action of a catalyst so as to prepare epoxy ester and then adding acrylic monomers and an initiator under certain conditions. A self-drying type antirust coating can be prepared with the acrylic acid-epoxy ester hybrid resin provided by the invention as a main film forming substance; a dried anticorrosive coating can also be prepared, especially coatings for curtain spraying sliver-coated mirrors, color films and aluminum mirrors; the coatings can meet coating process requirements of a wide-curtain spraying and coating production line with a maximum length of 3 m and are completely dried when baked at a temperature of 130 to 150 DEG C for 5 to 3 min, a film obtained after complete drying has excellent anticorrosion performance, can resist CASS, dampness, dryness and water with a temperature of 60 DEG C for more than 240 h, satisfy requirements of edging and texturing process of a downstream client and do not suffer from edge blackening and corrosion of clad layers.

Description

technical field [0001] The invention relates to an epoxy ester resin, in particular to an acrylic acid-epoxy ester hybrid resin and a paint containing the resin. Background technique [0002] Traditional mirrors can be divided into two categories according to the material of the metal reflective layer on which they are plated, namely silver mirrors and aluminum mirrors. With the development of science and technology, decorative mirrors that are plated with metals of other colors to form colors are collectively called color film (color mirror) in recent years. . Traditionally, in the mirror industry, the coatings that adopt the method of curtain spraying on the mirror production line are collectively referred to as mirror back coatings, which can be divided into: silver mirror back paint, aluminum mirror back paint, color film paint and glass according to the substrate. paint. [0003] Silver mirrors are divided into copper-silver mirrors and copper-free mirrors. The produc...
