Problems solved by technology

[0003] Existing sealant products only play a physical role in the harsh conditions of direct erosion of marine environments such as offshore oil and gas production platforms, wharf steel columns, foundations of offshore wind power towers, cross-sea bridges, hulls, and coastal buildings. As a result, marine biological erosion often occurs, more marine organisms are attached and adsorbed in a large area, and molds multiply and grow in large numbers, and after long-term use of sealants in this environment, colloidal cracking, pulverization and debonding will occur, which cannot be used for a long time Effectively acts as an anti-fouling and anti-mildew seal

Embodiment approach

[0013] In one embodiment of the present invention, substances such as 8-methyl-N-vanillyl-6-nonenamide are added to the sealant system, especially the silicone sealant system, as an antifouling agent, so that it has a good long-term effect on the substrate. Effective antifouling effect. The main mechanism of action of the antifouling agent is to force the external adsorbent to fail to attach through its own irritation, so as to achieve the antifouling effect.

[0014] In one embodiment of the present invention, the crosslinking agent may be methyl triethoxysilane, methyl tributylketoxime silane, vinyl tributylketoxime silane, ethyl silicate and the like.

[0015] In one embodiment of the present invention, the filler may be calcium carbonate, talc powder, titanium dioxide, ceramic microspheres, clay, diatomaceous earth, kaolin, silicon dioxide and the like.

[0016] In one embodiment of the present invention, the pigment can be iron red, cyanochrome yellow, blue powder, carbo...

Embodiment 1

[0027] The sealant of this embodiment is made from the following components by mass:

[0028]

[0029]

[0030] Take 10 parts of base glue, 10 parts of antifouling agent and 10 parts of antifungal agent and vacuumize and stir in a double planetary mixer, the vacuum degree is -0.09MPa~-0.1MPa, the stirring speed is 50r / min, and the stirring time is 30~50min , dispersed evenly as a small antifouling agent for later use.

[0031] The production of silicone sealants is carried out according to the conventional process. First, the liquid raw materials are added to the kettle according to the formula ratio, and then the fillers are added in turn. After high-speed dispersion and stirring, the prepared additives are added. The small antifouling agent is cleaned up at the last time When dry powder is added, gray silicone sealant can be obtained.

Embodiment 2

[0033] The sealant of this embodiment is made from the following components by mass:

[0034]

[0035] Concrete production technology is with embodiment 1.

Abstract

The invention provides a sealant composite and a sealant. The sealant composite comprises basic glue and a mould inhibitor, wherein the mould inhibitor is selected from one or a plurality of 8-oxine copper, ethyl tin chloride, tributyltin chloride, phenyl mercury oleate, pentachlorophenol, N-phenylmaleimide and trichlorophenyl maleimide. With the adoption of the sealant, the problems that marine organism are eroded and attached, mould massively propagates under humid marine environment can be effectively solved and prevented.

Description

technical field [0001] The invention relates to a polymer sealing material, in particular to a sealant composition and a sealant for improving the anti-mildew or anti-mildew and anti-fouling properties of substrates used in marine environments. Background technique [0002] The substrate in the marine environment will be eroded and attached by different organisms in the ocean during use, resulting in severe corrosion of the substrate or high-intensity load. The humid marine environment promotes the growth of a large number of molds, which affects the performance and service life of the substrate, causing economic losses and even threatening personal safety. Therefore, research on marine anti-fouling and anti-mildew materials has been highly valued by related industries. [0003] Existing sealant products only play a physical role in the harsh conditions of direct erosion of marine environments such as offshore oil and gas production platforms, wharf steel columns, foundatio...
