Embodiment 1

[0079] Table 1

[0080]

[0081] The proportioning ratio of each raw material component of the cleaning agent of this embodiment is shown in Table 1. Among them, the fatty alcohol polyoxyethylene polyoxypropylene ether is DD306 produced by Shanghai Dongda Chemical; the complexing agent is sodium tartrate.

[0082] Preparation of silicon-modified polyether:

[0083] (1) Preparation of polyether: in pressure reactor, add 100 parts of C 12 ~C 14 Fatty Alcohols (CAS: 80206-82-2) and KOCH 3 (the dosage is C 12 ~C 14 0.2% of the fatty alcohol weight), replace the air in the kettle with nitrogen for 3 times, heat up to 110°C, and dehydrate for 30min under a vacuum environment below -0.09MPa. Then the temperature was raised to 120°C, and ethylene oxide was slowly added dropwise (ethylene oxide and C 12 ~C 14 The molar ratio of aliphatic alcohol is 8:1), and the ring-opening polymerization reaction is carried out under the conditions of pressure 0.2MPa and temperature 140°C....

Embodiment 2

[0100] The proportioning ratio of each raw material component of the cleaning agent of this embodiment is shown in Table 1. Among them, the fatty alcohol polyoxyethylene polyoxypropylene ether is DD310 produced by Shanghai Dongda Chemical; the complexing agent is sodium heptose.

[0101] Preparation of silicon-modified polyether:

[0102] (1) Preparation of polyether: In a pressure reactor, add 100 parts of isomerized decanol (EXXAL TM 10) and NaOH (the amount of which is 0.15% of the weight of isomeric decanol), replace the air in the kettle with nitrogen for 3 times, heat up to 110° C., and dehydrate for 30 min under a vacuum environment below -0.09 MPa. Then heat up to 120°C, slowly add ethylene oxide dropwise (the molar ratio of ethylene oxide to 5:1), carry out the ring-opening polymerization reaction at a pressure of 0.2MPa and a temperature of 135°C, dropwise add ethylene oxide After the alkane is finished, the aging reaction is carried out for 30 minutes to obtain th...

Embodiment 3

[0119] The proportioning ratio of each raw material component of the cleaning agent of this embodiment is shown in Table 1. Among them, the fatty alcohol polyoxyethylene polyoxypropylene ether is DD310 produced by Shanghai Dongda Chemical; the complexing agent is sodium gluconate.

[0120] Preparation of silicon-modified polyether:

[0121] (1) Preparation of polyether: In a pressure reactor, add 100 parts of isomeric tridecanol (EXXAL TM 13) and NaOCH 3 (The amount is 0.25% of the weight of isomeric tridecyl alcohol), replace the air in the kettle with nitrogen for 3 times, heat up to 110° C., and dehydrate for 30 minutes in a vacuum environment below −0.09 MPa. Then the temperature was raised to 120°C, and ethylene oxide was slowly added dropwise (the molar ratio of ethylene oxide to isotridecyl alcohol was 9:1), and the ring-opening polymerization was carried out at a pressure of 0.3 MPa and a temperature of 135°C. After the dropwise addition of ethylene oxide is complet...

Abstract

The invention discloses a cleaning compound for spraying and a preparation method thereof. The cleaning compound comprises the following raw materials by weight: 1 to 5% of fatty alcohol polyoxyethylene polyoxypropylene ether, 3 to 8% of silicon modified polyether, 1 to 5% of sodium dodecylbenzenesulfonate, 1 to 3% of butynediol polyoxyethylene ether, 5 to 10% of triethanolamine, 0.1 to 2% of complexing agent, with the balance being water, wherein the silicon-modified polyether has a number-average molecular weight of 200 to 2000 g / mol and has a general structural formula as described in the specification. In the formula, R is a straight-chain or branched-chain C6-18 alkyl group; R' is a straight-chain or branched-chain C1-10 alkylene group; m is in a range of 1 to 10; n is in a range of 0to 5; and m and n are both integers. The cleaning compound provided by the invention is highly efficient and environmentally friendly; and the components of the cleaning compound interact to producesynergism, so the cleaning compound has the excellent performance of good spreadability on the surfaces of oil stains, good detersive power, low foam, alkali resistance and the like, and under the conditions of high and medium contents of alkali, the cleaning compound is free of layering and hydrolysis and can maintain stable in a long time.

Description

technical field [0001] The invention relates to a cleaning agent for spraying and a preparation method thereof. Background technique [0002] As we all know, in production and life, there are many things that need to be cleaned, and there are many types and links that need to be cleaned, such as: oil cleaning on the surface of objects, dust removal or surface rust prevention, etc. Common manual cleaning methods are slow and costly. However, spray cleaning can clean objects in batches, which has the advantages of high efficiency, strong controllability and low cost. Surfactants have strong wetting, emulsifying, washing and solubilizing abilities, and are important components of spray cleaning agents. At present, there are many kinds of surfactants that can be used for spray cleaning, but there are also the following problems: (1) the existing low-foaming surfactants have weak cleaning power, and are easy to separate out or It is easy to decompose, so that the cleaning effec...
