preparation example Construction

[0072] The preparation method of above-mentioned glass wine bottle baking varnish comprises the following steps:

[0073] a. Preparation of color paste: Add water-based acrylic modified epoxy ester resin and water into the dispersion tank, disperse at a medium speed of 600-800r / min for 15 minutes, then slowly add co-solvent, toner, defoamer, dispersant and wetting agent agent, high speed 1000~1500r / min disperse for 25~35min, grind the high speed dispersed slurry twice with a sand mill, and prepare the color paste for later use;

[0074] b. Preparation of component 1: Add water-based acrylic modified epoxy resin, high methyl etherified melamine formaldehyde resin and water into the dispersion tank, disperse at a medium speed of 600-800r / min for 15min, then slowly add leveling agent to thicken agent and the color paste prepared in step a, disperse at a high speed of 1000-1500r / min for 30-35min, take a sample to detect that the finished product fineness of component 1 is less tha...

Abstract

The invention discloses an environment-friendly shockproof water-based acrylic acid amino glass winebottle stoving varnish, and a preparation method and the application thereof. The stoving varnish comprises a component 1 and a component 2 as well as self-prepared slurry, wherein the cooperation of water-based acrylic acid modified epoxy ester resin, high methylated melamine formaldehyde resin and naphthalene sulfonic acid catalyst is utilized, and before using, mixing with a propyl group triethoxy silane coupling agent for diluting is performed, so that the glass winebottle stoving varnish baked at the temperature of 135 to 145 DEG C has excellent paint film shock resistance, high gloss, excellent repaint performance as well as outstanding paint film adhesive force; the content of VOC (volatile organic compound) of products can be reduced greatly, the TVOC (total volatile organic compound ) of the glass winebottle stoving varnish can be controlled to be lower than 68 g / L, and the environmental protection performance is obvious.

Description

technical field [0001] The invention relates to a glass wine bottle baking varnish and a preparation method thereof, in particular to an environment-friendly impact-resistant water-based acrylic amino glass wine bottle baking varnish, a preparation method and an application thereof. Background technique [0002] With the wheels of the modern industrial revolution rolling forward, resource and environmental issues have become a pair of major contradictions in the sustainable development of today's society. The oil crisis directly led to soaring crude oil prices, greatly increasing the cost of raw materials for industrial coatings, and the market competition in quality and price will inevitably lead to the survival of the fittest in some enterprises. At the same time, the emission of VOC (Volatile Organic Compounds) has directly brought serious pollution to the environment, and environmental protection issues have increasingly been highly concerned and regulated by countries a...
