preparation example Construction

[0024] When the source of the styrene-acrylic acid-maleic anhydride copolymer is self-prepared, the preparation method preferably includes the following steps:

[0025] (1) Acrylic acid, maleic anhydride, sodium lauryl sulfate and water are mixed to obtain a mixed solution;

[0026] (2) mixing said mixed solution, styrene and initiator to carry out polymerization reaction;

[0027] (3) After the reaction is finished, the reaction solution is cooled to normal temperature, and the pH is adjusted with lye to obtain a styrene-acrylic acid-maleic anhydride copolymer solution;

[0028] In the present invention, the molar ratio of the acrylic acid, maleic anhydride and styrene is preferably (0.1-1):(0.1-1):(0.1-1).

[0029] In the present invention, the amount of sodium lauryl sulfate is preferably 0.5% to 3% of the total mass of acrylic acid, maleic anhydride and styrene, more preferably 1% of the total mass of acrylic acid, maleic anhydride and styrene . In the present invention...

Embodiment 1

[0038] (1) In the reactor, add acrylic acid and maleic anhydride in a molar ratio of 1:1, then add sodium lauryl sulfate and water with a total monomer mass of 0.6%, stir and heat to 70°C;

[0039] (2) in the reactor, dropwise simultaneously the initiator of the styrene of the same molar number as acrylic acid and monomer gross mass 2%, the dropping time is 2h;

[0040] (3) After reacting for 4 hours, cool down to normal temperature, adjust the pH to 6 with lye, and obtain the styrene-acrylic acid-maleic anhydride copolymer.

[0041] The weight average molecular weight of the copolymer was measured by gel chromatography, and the result showed that the weight average molecular weight of the styrene-acrylic acid-maleic anhydride copolymer was 12530.

Embodiment 2

[0043] The styrene-acrylic acid-maleic anhydride copolymer that 0.1g embodiment 1 obtains is added to the detergent of 99.9g (this detergent contains the tensio-active agent of 16% weight portion, and wherein LAS accounts for 3%, and AEO accounts for 8%, AES5%, the remaining functional additives include 1% citric acid, 1% carboxymethyl cellulose, 0.2% HEDP, 0.5% NaCl, the pH value of the detergent is 7.5), stir evenly to obtain styrene-acrylic acid-horse Washing products with 0.1% toric anhydride copolymer content. Carry out washing and whiteness test on polyester fiber stained cloth, the test method is in accordance with GB / T 13174-2008 "Determination of Detergency and Cycle Washing Performance of Detergents for Clothing", and carbon black is used instead of the national standard JB-01 dirty liquid. The obtained results are listed in Table 1.

Abstract

The invention provides a cleaning product containing styrene-acrylic acid-maleic anhydride copolymer. In the invention, the styrene-acrylic acid-maleic anhydride copolymer has a hydrophilic anion functional group and a hydrophobic carbon-carbon chain structure and is capable of endowing molecules with excellent hydrophilic and lipophilic properties; a styrene and acrylic acid chain has a functionof absorbing dirt; acrylic acid and maleic anhydride have electrostatic repulsion and can stably disperse the copolymer absorbing dirt in a cleaning solution, so that the copolymer can achieve an effect of resisting against dust deposition during the cleaning process. When the cleaning product provided by the invention is used for cleaning polyester fiber fabrics, an excellent effect of resistingagainst dust deposition can be achieved, the whiteness of fabrics can be maintained and the color and luster of fabrics can be protected.

Description

technical field [0001] The invention relates to the technical field of detergents, in particular to a washing product containing styrene-acrylic acid-maleic anhydride copolymer and its application. Background technique [0002] Clothing Detergent is a mixture of surfactants and builders as main components. Under the action of stirring or external rubbing, the dirt is rolled away from the fabric, and the oil stains that are separated from the fabric are wrapped by surfactants, dispersed in water in the form of "micelle", and then taken away by foam, so as to achieve the effect of decontamination. [0003] In the past two decades, laundry detergents have developed rapidly, and washing products have been continuously enriched, showing the characteristics of high efficiency, economy and safety. However, the secondary decontamination ability of the detergent is poor, and the white fabric becomes gray due to the redeposition of dirt after the fabric is washed, and the color fabri...
