Abstract
The invention discloses a fingerprint-resistant scratch-resistant varnish which is formed by mixing the following materials in percentage by weight: 40-65% of acrylic resin, 5-18% of polyester resin, 10-25% of amino resin, 5-15% of polyurethane curing agent and 0.5-2.5% of additive. The fingerprint-resistant varnish has the functions of fingerprint resistance and nail scratch resistance. After a finger touches the paint film surface and then removed, the fingerprints obviously disappear and can be wiped off easily; and no obvious scratch appears after the nail scratches the paint film surface. The test proves that the fingerprint resistance and scratch resistance are comprehensive performance of multiple measurable indexes, such as adhesive force, hardness, toughness, gloss, medium resistance and the like. The varnish can be easily attached onto the coating layer, and has excellent gloss and color retentivity; and the thickness is 5-15 micrometers, the baking temperature is 195-200 DEG C, and the baking time is 150-180 seconds. The paint film is dried and subjected to blast cooling, and a PE (polyethylene) protective film is attached to the upper surface of the stainless steel plate with the fingerprint-resistant varnish, thereby preventing the fingerprint-resistant varnish coating from being scratched in the process of transportation, use or the like.
Description
Technical field
The present invention relates to a kind of coating of chemical field, coating manufacture field used by Color Stainless Steel ground, is specifically related to plated film colored stainless steel plate surface anti-fingerprint, scratch resistance varnish.
Background technology
Plated film colored stainless steel plate, bright-colored, be widely used in high-grade furnishing fields, as aspects such as hall wallboard, top ceiling, cage plate, truck board, building decoration, signboards.
Protect light for a long time for making plated film colored stainless steel plate and protect look, anti-fingerprint, scratch resistance, finally reach long-term high decorative effect, needs to protect coated surface, and being coated with last layer varnish on its surface is most economical, the most effective approach.At present, similar on the market quality product is uneven.There is provided quality products in order to long-term stability to user, seminar is through the strict development sequence such as market study, formulating of recipe, formulation optimization, pilot scale checking, large production lot production, and anti-fingerprint of new generation, scratch resistance varnish have entered into market smoothly.
Summary of the invention
The object of this invention is to provide a kind of baking-type varnish, it is coated in the colored coated surface of stainless steel plate, make its surface have anti-soil, anti-fingerprint, scratch resistance function, the paint film transparency itself is good, glossiness is high, hardness is high, snappiness is good, meets damage resistant and processibility.
Technical scheme of the present invention is as follows: the scratch resistant varnish of a kind of anti-fingerprint, is characterized in that: comprise following constituent materials, presses column weight amount percentage mix and forms:
Acrylic resin: 40-65
Vibrin: 5-18
Aminoresin: 10-25
Polyurethane curing agent: 5-15
Additive: 0.5-2.5.
Varnish of the present invention, relative to prior art, has following features:
The index that anti-fingerprint varnish of the present invention reaches: pencil hardness>=3H, the solvent wiping of resistance to MEK>=100 time, gloss (60
0)>=110, bending inside and outside 90
0, paint film does not destroy.
Anti-fingerprint varnish of the present invention also has the hydrochloric acid of resistance to 3% and the effect of 3% sodium hydroxide alkaline solution, and salt fog resistance reaches more than 168 hours.
Anti-fingerprint varnish of the present invention has the function of anti-fingerprint and the scuffing of anti-nail, and after coating surface finger touch, remove finger, fingerprint obviously disappears, and is easy to wiped clean, draws coating surface with nail, without obvious cut.Sum up in test: anti-fingerprint, resistance to marring are the general performances of the multiple quantifiable indicators such as paint film such as sticking power, hardness toughness, gloss, resistance to medium.
Anti-fingerprint varnish application of the present invention is on the Color Stainless Steel surface of plated film; be easy to be attached to above coatings; protect light tint retention excellent; thickness 5-15 micron; storing temperature 195 DEG C-200 DEG C, baking time 150-180 second, air blast cooling after drying; then attach one deck PE protective membrane at the stainless steel plate upper surface applying anti-fingerprint varnish, be scratched in the processes such as transport use to prevent anti-fingerprint varnish coating.
Anti-fingerprint varnish of the present invention, can complete embodiment coatings metal-like, for a long time coatings is shielded, be the varnish with the performance such as weather-proof, high rigidity, high tenacity, high tack, high clarity, scratch resistance, anti-fingerprint, media-resistant.
