Embodiment 1

[0018] Step A: Preparation of environmental glass adhesive.

[0019] Weighing according to the raw material composition and mass percentage of the environmentally friendly glass adhesive:

[0020] Bi 2 o 3 45%; ZnO20%; B 2 o 3 25%; 2 o 3 4%; SiO 2 1%; CaO3%; TiO 2 2%;

[0021] Mix the above-mentioned raw materials that have been weighed evenly, heat them in a high-temperature furnace, and heat them at 1200°C for 30 minutes. After quenching the melted glass powder particles with deionized water, ball mill them to 0.5-2 microns, and sieve them through a 200-mesh sieve for later use. , The glass powder obtained in this way does not contain harmful substances such as Pb, Cd, Hg, Cr(VI).

[0022] Step B: Preparation of carrier.

[0023] Add 10% by weight of ethyl cellulose resin to 90% organic solvent, dissolve completely in a constant temperature water tank at a temperature of 75°C, and filter through a 200-mesh filter to obtain an organic vehicle;

[0024] The organic ...

Embodiment 2

[0028] Step A: Preparation of the environmentally friendly glass binder.

[0029] Weighing according to the raw material composition and mass percentage of the environmentally friendly glass binder:

[0030] Bi 2 o 3 55%; B 2 o 3 22%; SiO 2 1%;TiO 2 0.5%; NiO1%; NiO 2 0.5%; ZnO20%.

[0031] Mix the above-mentioned raw materials that have been weighed evenly, heat them in a high-temperature furnace, and heat them at 900°C for 60 minutes. After quenching the melted glass powder particles with deionized water, ball mill them to 0.5-2 microns, and sieve them through a 400-mesh sieve for later use. The glass powder obtained in this way does not contain harmful substances such as Pb, Cd, Hg, Cr(VI). Step B: Preparation of carrier. Add 30% ethyl cellulose resin to 70% organic solvent by weight percentage, dissolve completely in a constant temperature water tank at a temperature of 100°C, and filter through a 200-mesh filter to obtain an organic vehicle;

[0032] The organic...

Embodiment 3

[0036] Step A: Preparation of the environmentally friendly glass binder.

[0037] Weighing according to the raw material composition and mass percentage of the environmentally friendly glass binder:

[0038] Bi 2 o 3 50%; B 2 o 3 25%; 2 o 3 0.5%; SiO 2 1%; CaO0.5%; TiO 2 1%; NiO 2 2%; ZnO20%.

[0039] Mix the above-mentioned raw materials that have been weighed evenly, heat them in a high-temperature furnace, and heat them at 1000°C for 50 minutes. After quenching the melted glass powder particles with deionized water, ball mill them to 0.5-2 microns, and sieve them through a 300-mesh sieve for later use. The glass powder obtained in this way does not contain harmful substances such as Pb, Cd, Hg, Cr(VI).

[0040] Step B: Preparation of carrier.

[0041] Add 20% of ethyl cellulose resin to 80% organic solvent by weight percentage, dissolve completely in a constant temperature water tank at a temperature of 95°C, and filter through a 200-mesh filter to obtain an orga...

Abstract

The invention relates to an environment-friendly ink paste for automobile glass and a preparation method thereof. The ink paste is characterized by comprising 8-45wt% of a carbon black powder with average particle size in the range of 0.2-8 mum, 3-15wt% of a carrier, 2-15wt% of a solvent, 0.5-2wt% of a dispersing agent and the balance of a binder. The ink paste for automotive glass provided by the invention uses an environment-friendly glass powder as the binder, and an environment-friendly organic reagent as the solvent and a diluent; the prepared paste does not contain the six substances prohibited by the EU RoHS directive (Pb, Cd, Hg, Cr (VI), polybrominated biphenyls PBB and poly brominated diphenyl ethers PBDE) and is in line with the EU RoHS directive 2005 / 84 / EC concerning phthalate, so as to achieve a true sense of environmental protection, and benefit import and export of domestic ink for automobile glass.

Description

technical field [0001] The invention relates to an environment-friendly ink paste for automobile glass and a preparation method thereof. Background technique [0002] The series of pastes for automotive glass can be divided into three categories: inks for laminated front glass, inks for side and rear tempered glass, and defrosting silver pastes for rear tempered glass. Generally, the first two types are collectively referred to as inks for automobile glass, which are applied to the periphery of automobile glass to play the role of decoration and anti-ultraviolet when the car is used; defrosting silver paste is a method of electric heating to remove fog and condensation on the glass. Frost. Due to the vigorous development of my country's automobile industry in recent years, the output of automobiles has increased year by year, and the demand for silver paste and ink for automobile glass has also increased sharply. [0003] The environmental standards of the electronic paste...
