JPS61176672A - Anti-fouling paint composition - Google Patents

Abstract

PURPOSE:To provide the titled composition having long active life in water, giving a coating film having high deterioration resistance, having excellent antifouling effect and safety, and suitable for the coating of ship, etc., by using a copper-coordinated manganese ethylenebisdithiocarbamate as an active component. CONSTITUTION:The objective composition is produced by pulverizing copper- coordinated manganese ethylenebisdithiocarbamate e.g. to <=3mu, and adding the powder to a paint component at a ratio of preferably 1-50%.

Description

[Detailed description of the invention] (Industrial application field) The present invention relates to an antifouling paint composition, and more particularly.

The present invention relates to an antifouling paint composition containing copper-coordinated Manganese ethylene bisdithiocarbamate as an active ingredient.

(Prior art) Industrial equipment such as instruments and devices in hot and humid places or underwater, communication and transportation pipes, ship hulls, cooling and heat exchange pipes,
Rafts, buoys, inner surfaces of aquariums, underwater structures, etc. are infested with aquatic organisms such as bacteria, fungi, molds, insects, microorganisms, molluscs, etc., which can cause a great deal of damage. It has caused a great deal of damage in terms of repairs and repainting.

For example, in a ship, a several percent increase in resistance to the ship's hull in seawater causes a decrease in speed and fuel efficiency.
This results in extremely large losses and impedes heat conduction in the cooling water heat exchange pipes, and the operation must be stopped at regular intervals to remove these deposits.

Conventionally, inorganic metal compounds such as copper, mercury, and tin, organic tin, organic chlorine compounds,
Organic compounds such as organic sulfur compounds have been incorporated into paints and applied to targeted areas. All of them have drawbacks such as being highly toxic to humans and animals, causing environmental pollution, and not being sufficiently effective over a long period of time when used as a paint composition.

(Problems to be Solved by the Invention) Under these circumstances, there is a desire for a coating composition that is safe for coating operations, has a long residual effect in water, and has little deterioration in the physicochemical properties of the coating film.

(Means for solving the problem) The present invention contains copper-coordinated Manganese ethylene bisdithiocarbamate in a paint, which is highly safe for the human body and fish, and prevents adherent contamination that occurs in water. The object of the present invention is to provide an antifouling paint composition that prevents deterioration of the physicochemical properties of the paint. Steel-coordinated Manganese ethylene bisdithiocarbamate has traditionally been used as a fungicide for agricultural and horticultural purposes.

Special Publication No. 56-35642 and Special Publication No. 44-2821
Disclosed in the issue. Copper ions are extremely stably coordinated to manga21 diethylene bisdithiocarbamate.

The coating composition of the present invention contains animal oil,
Those used in known paints, such as vegetable oils, natural oils, acrylic resins, and vinyl resins, can be used. A pigment-based pigment, a spreading agent, a fixing agent, an anti-caking agent, and other auxiliary components can be appropriately blended into this coating component.

The content of the active ingredient of the present invention in the paint can be changed as desired, but is preferably 1 to 50%. However, after addition, it may be ground and stirred in a vehicle.

Furthermore, the active ingredient of the present invention can be used alone or in combination with other known antifouling components as an antifouling paint.

(Examples and Effects of the Invention) Example 1 20 parts of copper-coordinated Manganese ethylene bisdithiocarbamate finely pulverized to 3μ or less, 15 parts of talc, 30 parts of pine resin
15 parts of acrylic resin and 20 parts of xylene were kneaded, mixed and dispersed.

Example 2 25 parts of copper-coordinated Manganese ethylene bisdithiocarbamate finely ground to 3μ or less, 15 parts of titanium white, 25 parts of pine resin, 20 parts of methyl isobutyl ketone, 1 part of xylene
Five parts were kneaded, mixed, and dispersed to form a paint.

Example 3 10 parts of steel-coordinated Manganese ethylene bisdithiocarbamate finely ground to 3μ or less, 5 parts of suboxide steel, 10 parts of titanium white, 30 parts of pine resin, 15 parts of acrylic resin, and 20 parts of toluene were kneaded and mixed 1 It was dispersed and made into a paint.

Test Example 1 A tin plate (undercoated with anti-corrosion paint) was used as a test piece.

Test Example 2 Put the antifouling paint prepared in Example 1 into a glass bottle, and
After being stored at 0°C for one month, it was taken out and its changes over time were investigated. In this case, there was almost no change in the viscosity of the paint between the time of manufacture and after storage.
