Abstract
The invention discloses a Teflon finishing coat, and belongs to the technical field of coating. The Teflon finishing coat is prepared from the following raw materials in parts by weight: 40-50 parts of polytetrafluoroethylene emulsion, 8-12 parts of amino resins, 30-45 parts of hexamethylene diisocyanate, 5-8 parts of ethyl alcohol, 4-5 parts of ethylene glycol ethyl ether, 15-20 parts of titanium-nickel composite pigment, 1-3 parts of silicon dioxide colloid, 1-3 parts of 30% of ammonium hydroxide of and 5-10 parts of water. Compared with the conventional Teflon finishing coat, the Teflon finishing coat can be instantly solidified at a relatively low temperature.
Description
Technical field
The invention belongs to technical field of coatings, relate in particular to a kind of Teflon finish paint.
Background technology
Teflon finish paint is a kind of fluorine coating taking tetrafluoroethylene as matrix resin, because the cause of pronunciation is referred to as again Teflon, Teflon, teflon, fe fluon conventionally.Because it has superior adherence and oilness, non-stick finish coat or be not stained with finish paint is otherwise known as.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 of selling on market has lot of advantages, because its solidification value is too high, set time is longer, make it in the time that processing is used, increased difficulty of processing and wasted process period, thereby having improved 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, made by the raw material of following parts by weight:
40 parts～50 parts of ptfe emulsions;
8 parts～12 parts, aminoresin;
30 parts～45 parts of hexamethylene diisocyanates;
5 parts～8 parts of ethanol;
4 parts～5 parts of ethylene glycol ethyl ethers;
15 parts～20 parts of titanium nickel composite pigments;
1 part～3 parts of silicon dioxide colloids;
30% 1 part of ammoniacal liquor～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 intermediate product I that water and A step make is put into shredder, is ground to fineness and is less than 10 microns, obtains intermediate product II;
C, the intermediate product II that B step is made are poured in high speed dispersor, add ptfe emulsion and silicone oil to disperse 2 hours～3 hours with the rotating speed of 900 revs/min～1000 revs/min, make.
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 are made totally enclosed hexamethylene diisocyanate, then mixes and uses with aminoresin, and Teflon finish paint of the present invention can be cured at a lower temperature fast.
