Problems solved by technology

[0007] However, due to the weak penetrating ability of the oxidizing bactericidal algaecide, the existing bactericidal algaecide for concave-convex circulating water has no obvious effect on groups of algae and slime, and when there are organic matter, hydrogen sulfide, and ferrous When ionized, the bactericide and algicide will react with these substances to form harmful organic halides, and the oxidative bactericide and algicide are greatly affected by organic matter and reducing substances in the water, and the duration of the drug effect is short

preparation example 1

[0044] Preparation Example 1: (1) Crush the attapulgite, pass a 20-mesh sieve, add 6 times its mass to a hydrochloric acid solution, stir at 80°C for 2h, centrifuge at 1500r / min for 15min, and wash with deionized water To neutral, dry at 100℃, the concentration of hydrochloric acid solution is 31%;

[0045] (2) Add phosphinic acid-based polyacrylic acid, hydroxyethylidene diphosphonic acid and polyacrylic acid to the resultant of step (1), mix uniformly and dry, to obtain modified attapulgite, attapulgite and phosphinic acid-based The mass ratio of polyacrylic acid, hydroxyethylidene diphosphonic acid and polyacrylic acid is 1:0.3:0.1:0.2.

preparation example 2

[0046] Preparation Example 2: (1) The attapulgite was crushed, passed through a 20-mesh sieve, added to a hydrochloric acid solution of 8 times its mass, stirred at 85°C for 1.5h, centrifuged at 1600r / min for 13min, and deionized water Wash to neutral, dry at 110℃, the concentration of hydrochloric acid solution is 31%;

[0047] (2) Add phosphinic acid-based polyacrylic acid, hydroxyethylidene diphosphonic acid and polyacrylic acid to the resultant of step (1), mix uniformly and dry, to obtain modified attapulgite, attapulgite and phosphinic acid-based The mass ratio of polyacrylic acid, hydroxyethylidene diphosphonic acid and polyacrylic acid is 1:0.4:0.2:0.3.

preparation example 3

[0048] Preparation Example 3: (1) The attapulgite was crushed, passed through a 20-mesh sieve, added to a hydrochloric acid solution of 10 times its mass, stirred at 90°C for 1 hour, centrifuged at 1800r / min for 10 minutes, and washed with deionized water To neutral, dry at 120℃, the concentration of hydrochloric acid solution is 31%;

[0049] (2) Add phosphinic acid-based polyacrylic acid, hydroxyethylidene diphosphonic acid and polyacrylic acid to the resultant of step (1), mix uniformly and dry, to obtain modified attapulgite, attapulgite and phosphinic acid-based The mass ratio of polyacrylic acid, hydroxyethylidene diphosphonic acid and polyacrylic acid is 1:0.5:0.3:0.4.

Abstract

The invention discloses a bactericidal algicide as well as a preparation method and an application thereof. The bactericidal algicide is prepared from the following raw materials in parts by weight: 10 to 15 parts of 2-hydroxyl-2, 3, 5-trichlorobenzophenone, 5 to 10 parts of 5-chloro-2-methyl-4-isothiazoline-3-ketone, 6 to 12 parts of sodium dichloroisocyanurate, 6.2 to 10.6 parts of modified zincsulfide, 10 to 15 parts of modified attapulgite, 2.6 to 4.6 parts of an adhesive, 4.8 to 8.6 parts of a penetrating agent and 10 to 20 parts of deionized water. The penetrating agent comprises the following components: a gemini quaternary ammonium salt cationic surfactant, polyethylene glycol, animal glue, sodium diethylhexyl sulfosuccinate and squalane. The bactericidal algicide provided by theinvention has the advantages of long efficacy time, good bactericidal and algicidal effects, adsorption of heavy metal ions and prevention of corrosion of a heat exchanger.

Description

Technical field [0001] The invention relates to the technical field of water treatment agents, and more specifically, it relates to a bactericidal and algaecide and its preparation method and application. Background technique [0002] Circulating cooling water plays an important role in the cooling system. Due to long-term circulation of circulating cooling water, the circulating cooling water contains a large number of bacteria. If it is used for too long, some algae will grow and produce rubbery deposits, sticky substances, When biological slime materials such as colloidal film or colored slime patterns are used as a cooling medium in an industrial cooling circulating water system, the heat transfer efficiency of the circulating cooling water system will be reduced, and the heat exchanger and pipes will be blocked or polluted. Seriously affect the normal operation of production equipment. [0003] With the rapid development of social economy and technological progress, water tre...
