Description
Technical Field
The invention relates to the technical field of anticorrosive primer, in particular to an epoxy zinc-rich anticorrosive primer and a preparation method thereof.
Background
the epoxy zinc-rich primer takes epoxy resin as a base material, polyamide as a curing agent, superfine zinc powder as a main antirust pigment, and a certain amount of aluminum paste and iron oxide red are added, so that the heat resistance can be improved, and the generation of zinc salt can be prevented. The paint has the advantages of excellent cathodic protection effect, excellent corrosion resistance, quick drying, strong adhesive force, good impact resistance and wear resistance, and good gas cutting performance and weldability. Has excellent adhesive force with steel after sand blasting treatment. The antirust primer is mainly used for temporary protection and corrosion prevention of steel surfaces, and can also be used for antirust primers of ships, bridges, offshore platforms and steel structures.
Because the zinc powder in the zinc-rich coating has high consumption and hydrophilic and oleophobic properties, the compatibility with epoxy resin is poor, the uniform dispersion of the zinc powder is difficult to realize, and the comprehensive performance of the coating is reduced.
Disclosure of Invention
in order to overcome the defects and shortcomings in the prior art, the invention aims to provide an epoxy zinc-rich anti-corrosion primer with excellent comprehensive performance and a preparation method thereof.

40-60 parts of curing agent
40-60 parts of organic solvent B.
When the epoxy resin is cured, internal stress is easily generated due to volume shrinkage, and the coating is also easily subjected to stress concentration due to the problem that the zinc powder is high in content and difficult to disperse, so that the overall mechanical property of the coating is poor. According to the invention, the organic silicon rubber is added into the coating, and under a certain curing condition, the epoxy group of the epoxy resin and the silicon oxygen group of the organic silicon rubber can be crosslinked, so that the epoxy group is consumed, the crosslinking density of a cured product is reduced, and the flexibility of the coating can be effectively improved under the action of physical curing of the organic silicon rubber; and the alkoxy of the organic silicon rubber is also reactive with the hydroxyl of the zinc powder, so that the surface property of the zinc powder can be improved, the dispersibility of the zinc powder in the coating is improved, and the overall mechanical property of the coating is also improved.

Preferably, the vulcanizing agent consists of 2, 5-dimethyl-2, 5-di-tert-butyl hexane peroxide and dicumyl peroxide in a weight ratio of 2-3: 1. Compared with the three single vulcanizing agents, the preferable compound vulcanizing agent can better improve the toughness of the organic silicon rubber, thereby improving the flexibility of the coating.
wherein the release agent is calcium stearate and/or zinc stearate.
Wherein the structural control agent is hydroxyl silicone oil.
The addition of the hydroxyl silicone oil can improve the active group content of the organic silicone rubber, strengthen the combination effect of the organic silicone rubber and the zinc powder, and improve the dispersibility of the coating, so that the zinc-rich coating has higher hardness and better impact resistance.

(3) Adding a vulcanizing agent into the rubber compound for mixing, and then vulcanizing in a vulcanizing machine to obtain vulcanized rubber;
(4) and (3) crushing the vulcanized rubber by using a liquid nitrogen freezing crusher to obtain the organic silicon rubber.

Vulcanized rubber is vulcanized in a mold, and therefore has a certain volume. According to the invention, vulcanized rubber is crushed, so that the vulcanized rubber can be applied to the epoxy zinc-rich coating, the modification effect of the organic silicon rubber is fully utilized, and the overall performance of the coating is obviously improved.

Comparative example 1
this comparative example differs from example 3 in that:
The organic silicon rubber is replaced by 150-mesh nitrile rubber powder with equal mass.
comparative example 2
this comparative example differs from example 3 in that:
the component A does not contain organic silicon rubber, and the zinc powder is treated by a silane coupling agent kh 550.
comparative example 3
This comparative example differs from example 3 in that:
the coating method of the comparative example was to mix the component a and the component B uniformly, spray the mixture on a substrate, and perform natural curing at room temperature.
The paint films of example 3 and comparative examples 1 to 3 were tested according to GB/T6739-2006, GB/T1720-1979, GB/T1731-1993, GB/T1732-1993 and GB/T1771-2007 for paint film hardness, paint film adhesion, paint film flexibility, paint film impact resistance and neutral salt spray resistance, respectively, with the test results as follows:
As can be seen from comparative example 1, the nitrile rubber has no obvious crosslinking effect on the coating, and the nitrile rubber plays a main role in physical film formation, so that the crosslinking degree of a paint film is higher, the integral hardness is higher, but the flexibility and the adhesiveness of the paint film are poorer, and the corrosion resistance of the paint film is more common due to uneven dispersion of zinc powder; as can be seen from comparative example 2, the silane coupling agent modified zinc powder can also effectively improve the dispersibility of the zinc powder, and after no silicone rubber participates in the zinc powder, the relative content of the zinc powder is improved, so that the corrosion resistance and hardness of the coating are relatively high, and the flexibility is improved compared with comparative example 1, while the nitrile rubber is an elastomer with better flexibility, which indicates that the physical blending of a rubber body and the epoxy resin have phase separation and are not beneficial to the improvement of the toughness of a paint film; as can be seen from comparative example 3, when the curing temperature is lower, the crosslinking action of the silicone rubber and the epoxy resin is weaker, so that the degree of crosslinking of the epoxy resin and the curing agent in the paint film is increased, the overall hardness of the paint film is increased, the flexibility is reduced, and the dispersibility of the zinc powder is not significantly improved, so that the paint film has substantially no advantage of corrosion resistance as compared with comparative example 1.
The above-described embodiments are preferred implementations of the present invention, and the present invention may be implemented in other ways without departing from the spirit of the present invention.
