Abstract
The invention discloses a kind of Teflon finish paint, belong to technical field of coatings.The present invention counts by weight, with ptfe emulsion 40 parts ~ 50 parts, 8 parts ~ 12 parts, aminoresin, hexamethylene diisocyanate 30 parts ~ 45 parts, ethanol 5 parts ~ 8 parts, ethylene glycol ethyl ether 4 parts ~ 5 parts, titanium nickel composite pigment 15 parts ~ 20 parts, silicon dioxide colloid 1 part ~ 3 parts, 30% ammoniacal liquor 1 part ~ 3 parts and 5 parts ~ 10 parts, water are prepared from as raw material.Compared with existing Teflon finish paint, the present invention can be cured fast at lesser temps.
Description
Technical field
The invention belongs to technical field of coatings, particularly relate to a kind of Teflon finish paint.
Background technology
The fluoro coatings of Teflon finish paint to be a kind of with tetrafluoroethylene be matrix resin, because pronunciation, is referred to as again Teflon, Teflon, teflon, fe fluon usually.Because it has superior adherence and oilness, be otherwise known as non-stick finish coat or be not stained with finish paint.It can be widely used in tableware, mould, kitchenware, household electrical appliances, furniture, science and technology, automobile, machinery, medicine etc.
At present, although the Teflon finish paint that market is sold has lot of advantages, because its solidification value is too high, set time is longer, making it when processing use, adding difficulty of processing and wasting process period, thus improve tooling cost.
Summary of the invention
The technical problem that the present invention solves is to provide the Teflon finish paint that a kind of solidification value is low, set time is short.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:
A kind of Teflon finish paint, be made up of the raw material of following parts by weight:
Ptfe emulsion 40 parts ~ 50 parts;
8 parts ~ 12 parts, aminoresin;
Hexamethylene diisocyanate 30 parts ~ 45 parts;
Ethanol 5 parts ~ 8 parts;
Ethylene glycol ethyl ether 4 parts ~ 5 parts;
Titanium nickel composite pigment 15 parts ~ 20 parts;
Silicon dioxide colloid 1 part ~ 3 parts;
30% ammoniacal liquor 1 part ~ 3 parts;
5 parts ~ 10 parts, water;
Its preparation method comprises the following steps:
A, by above-mentioned parts by weight, by hexamethylene diisocyanate, ethanol and ethylene glycol ethyl ether are put into reactor and are mixed, and react, until nco value is less than 0.5, obtain intermediate product I, for subsequent use;
B, by aminoresin, silicon dioxide colloid, titanium nickel composite pigment, 30% ammoniacal liquor, the obtained intermediate product I of water and step A puts into shredder, is ground to fineness and is less than 10 microns, obtain intermediate product II;
C, intermediate product II obtained for step B is poured in high speed dispersor, add ptfe emulsion and silicone oil disperses 2 hours ~ 3 hours with the rotating speed of 900 revs/min ~ 1000 revs/min, obtained.
Owing to adopting technique scheme, the beneficial effect that the present invention obtains is:
The present invention passes through first by hexamethylene diisocyanate, and ethanol and ethylene glycol ethyl ether make totally enclosed hexamethylene diisocyanate, then used in combination with aminoresin, and Teflon finish paint of the present invention can be cured at a lower temperature fast.
