Embodiment 1

[0029] The preparation method of the interfacial adhesion promoter of the present embodiment comprises the following specific steps:

[0030] Step 1: Add A81 aldehyde resin into a three-neck flask equipped with a condenser and stirring.

[0031] Step 2: Add TDI trimer, raise the temperature to 80° C., and react for 2 hours. Adding an appropriate amount of catalyst dibutyltin dilaurate while adding the TDI trimer can effectively shorten the reaction time.

[0032] Step 3, adding isopropyl titanate to continue the reaction for 2 h.

[0033] In step 4, the temperature is lowered to below 60°C and the material is discharged to obtain an interface adhesion promoter. The mass ratio of isopropyl titanate, TDI trimer and A81 aldehyde resin added in the above steps is 4:2:1. The interfacial adhesion promoter prepared by adding metal organic matter, polyisocyanate and hydroxyl-containing oligomer at this mass ratio is the most stable.

Embodiment 2

[0037] The preparation method of the interfacial adhesion promoter of the present embodiment comprises the following specific steps:

[0038] Step 1, adding solid hydroxy acrylic resin into a three-neck flask equipped with a condenser and stirring.

[0039]Step 2: Add TDI-TMP adduct, raise the temperature to 80° C., and react for 2 hours.

[0040] Step 3, adding aluminum isopropoxide to continue the reaction for 2 h.

[0041] In step 4, the temperature is lowered to below 60°C and the material is discharged to obtain an interface adhesion promoter. The mass ratio of aluminum isopropoxide, TDI-TMP adduct and solid hydroxyl acrylic resin added in the above steps is 4:2:1.

[0042] With the titanium white slurry of 35 parts by weight, the barium sulfate of 5 parts by weight, the anionic water-based acrylic acid modified polyurethane resin containing carboxyl group of 100 parts by weight, the auxiliary agent of 8 parts by weight, the interfacial adhesion promoter of 3 parts by w...

Embodiment 3

[0045] The preparation method of the interfacial adhesion promoter of the present embodiment comprises the following specific steps:

[0046] Step 1, epoxy resin is added in the there-necked flask with condenser and stirring.

[0047] Step 2: Add biuret N75, heat up to 80°C, and react for 2 hours.

[0048] Step 3, adding zirconate to continue the reaction for 2h.

[0049] In step 4, the temperature is lowered to below 60°C and the material is discharged to obtain an interface adhesion promoter. The mass ratio of zirconate, biuret N75 and epoxy resin added in the above steps is 4:2:1.

[0050] With 33 parts by weight of phthalocyanine blue paste, 100 parts by weight of carboxyl-containing anionic water-based fluorine-modified polyurethane resin, 10 parts by weight of auxiliary agent, 3 parts by weight of interface adhesion promoter and 20 parts by weight of deionized water Put it into a stainless steel cylinder for stirring and dispersing, set the speed at 700rad / min, and st...

Abstract

The invention relates to an interface adhesion improver. The interface adhesion improver is obtained through a reaction of a metal organic matter, polyisocyanate and a hydroxyl group-containing oligomer. The interface adhesion improver makes an aqueous monocomponent plastic coating and a noncrystalline plastic base material have excellent interface adhesion.

Description

technical field [0001] The invention relates to an organic compound added in paint, a preparation method of the organic compound, and an application of the organic compound, which belong to the technical field of paint. Background technique [0002] With people's increasing emphasis on environmental protection and energy, countries all over the world have enacted or are enacting increasingly strict laws and regulations to strictly limit the emission of VOC in coatings. In order to adapt to the transformation of the economic structure and the increasingly serious environmental problems, our country clearly proposes to accelerate the development of high-performance, energy-saving, functional coatings and supporting raw materials, especially the development of water-based automotive paints and water-based plastic coatings. Since various plastics and more and more derived compound products are widely used in people's daily life and industrial consumer goods industries, including...
