Abstract

The invention relates to the technical field of anti-fouling paints, and in particular relates to a preparation method of a natural fishnet antifoulant. The preparation method comprises the steps: extracting Naga chilli serving as a raw material to obtain a capsaicin liquid, extracting garlic serving as a raw material to obtain alliin concentrate, and reacting the capsaicin liquid and the alliin concentrate with palm oil, glycerol, denatonium benzoate, snail mucus and sodium carboxymethylcellulose under stirring to obtain the fishnet antifoulant. The adopted raw materials are environment-friendly and nontoxic; the prepared antifoulant is capable of paralyzing the nerves of attaching organisms and disturbing the mucus secretion of marine organisms, has inhibition effect on the propagation of the marine fouling organisms, does not destroy the marine environment and biological chain, can generate strong stimulus to the sense organs of the fouling organisms, and has good dispelling action on soft fouling organisms; the processed antifoulant is difficult to attach for the fouling organisms due to good smoothness, is capable of guaranteeing long-time permeation of anti-fouling components from the raw materials due to good permeability and has period of validity up to 2 years.

Description

A kind of making method of natural fishing net anti-fouling agent

Technical field

The present invention relates to antifouling paint technical field, be specifically related to a kind of making method of natural fishing net anti-fouling agent.

Background technology

Along with the raising of human living standard, the demand of sea-food is increased, fish for through excessive for many years, sea-food wretched insufficiency in ocean, thus sea farming industry is flourish, current aquaculture is based on coastal waters, off-lying sea cultivation ratio is also increasing year by year, and along with the development of this industry, newborn problem is arisen spontaneously, ocean environment is a corrosion, the environment that biodeterioration is serious, after the boats and ships settled organism of navigation, to obviously increase the friction resistance of surface navigation, the leaching sea degree of depth of fishing net constant temperature fishing gear is not generally 0-20m not etc., be easy to adhere to marine life, main species has algae, wheel animalcule, polyzoan, barnacle etc., and antifouling paint is one of main method solving marine anti-pollution problem, and current antifouling paint generally has certain toxicity, easily secondary pollution is caused to ocean environment, anti-fouling effect is very unobvious, the shortcoming that the antifouling time length is not grown.

Summary of the invention

The shortcoming that in unresolved prior art, fishing net anti-fouling agent exists, the object of the present invention is to provide a kind of nontoxic, pollution-free, good antifouling effect, the making method of the fishing net anti-fouling agent that the antifouling time is lasting.

The technical solution used in the present invention is: a kind of making method of natural fishing net anti-fouling agent, and it comprises following steps:

It is raw material that a, Yi Na add capsicum, the ethanolic soln that concentration is 35%-40% is added after being pulverized, the consumption of ethanolic soln is receive 1-1.5 times that adds capsicum weight, be heated to 40-55 DEG C, 25-30 minute is extracted under the high frequency of 45KHZ, be extracted after liquid reclaims ethanol and concentrate, obtain Capsaicin liquid;

B, onion is squeezed the juice after, add the aqueous solution in the ratio of 1:1, ultrasonic lixiviate 30-35 minute, centrifugal 15-18 minute under rotating speed is 5000r/min, get the 3%-5% of supernatant concentration to cumulative volume, obtain alliin concentrated solution;

C, plam oil, glycerine are warming up to 165-180 DEG C, stir 15-18 minute under speed is 200-220r/min stir speed (S.S.) after, be warming up to 200-210 DEG C, Keep agitation 12-14 hour under the rotating speed of 180-185r/min, add ammonium benzoate acyl saccharides Keep agitation 15-20 minute, add Capsaicin liquid, alliin concentrated solution, snail mucus Keep agitation 2-2.5 hour when being cooled to 90-95 DEG C, finally add Xylo-Mucine uniform stirring and keep 3-4 hour.

Wherein, in step c, each raw material mixing adding proportion is: Capsaicin liquid 5%-10%, alliin concentrated solution 8%-12%, snail mucus 15%-20%, Xylo-Mucine 2%-3%, ammonium benzoate acyl saccharides 0.0003%-0.0005%, plam oil 38%-50%, glycerine 18%-25%.

The equal environment-protecting asepsis of starting material of the present invention, making method is easy, the stain control agent produced can benumb the nerve of settled organism, interference marine organisms secreting mucus, restraining effect is had to the breeding of marine fouling organism, can not damage ocean environment and biologic chain, can the sense organ of intense stimulus fouling organism, this is had to drive attached effect preferably to software class fouling organism, the stain control agent slickness processed is better, and fouling organism is difficult to seek connections with, and perviousness is better, ensure that driving dirty composition in raw material can ooze out for a long time, validity period is 2 years.

Embodiment

It is raw material that a, Yi Na add capsicum, the ethanolic soln that concentration is 35% is added after being pulverized, the consumption of ethanolic soln is receive 1 times that adds capsicum weight, be heated to 40 DEG C, 25 minutes are extracted under the high frequency of 45KHZ, be extracted liquid and reclaim ethanol, extraction liquid is concentrated into 2% of cumulative volume, obtains Capsaicin liquid;

B, onion is squeezed the juice after, add the aqueous solution in the ratio of 1:1, ultrasonic lixiviate 30 minutes, under rotating speed is 5000r/min centrifugal 15 minutes, get supernatant concentration to 3% of cumulative volume, obtain alliin concentrated solution;

C, plam oil, glycerine are warming up to 165 DEG C, stir under speed is 200r/min stir speed (S.S.) after 15 minutes, be warming up to 200 DEG C, Keep agitation 12 hours under the rotating speed of 180r/min, add ammonium benzoate acyl saccharides Keep agitation 15 minutes, add Capsaicin liquid, alliin concentrated solution, snail mucus Keep agitation 2 hours when being cooled to 90 DEG C, finally add Xylo-Mucine uniform stirring and keep 3 hours.

Wherein, in step c, each raw material mixing adding proportion is: Capsaicin liquid 10%, alliin concentrated solution 10%, snail mucus 20%, Xylo-Mucine 2.9995%, ammonium benzoate acyl saccharides 0.0005%, plam oil 38%, glycerine 19%.
