Abstract
The invention discloses a preparation method for active dye acid soaping agent, which comprises the following steps of: a, successively adding fatty alcohol-polyoxyethylene ether AEO-15, PEG(polyethylene glycol)-200 and water into a 1000ml of reaction kettle, heating to 40-70DEG C, and stirring for 0.5-1 hour to dissolve the mixture; and b, successively adding quantitative maleic anhydride-crylic acid copolymer, diethanol amine and water into solution obtained in step a, and stirring for 0.5-2 hours at the temperature of 50-80DEG C to obtain an acid soaping agent product of which the solid content is 28%. The acid soaping agent obtained by the invention has a strong washing stain resistance capability and has an action on stabilizing a pH (potential of hydrogen) value, one working procedure of washing and one working procedure of neutralizing by weak acid can be reduced, sewage processing pressure is lightened, water is saved, and meanwhile, a corresponding cleaning requirement can be achieved.
Description
Technical field:
The present invention relates to a kind of reactive dyestuffs acid scouring agent, particularly a kind of preparation method of reactive dyestuffs acid scouring agent.
Background technology:
At present, that natural fiber relies on is comfortable, environmental protection, the high-performance such as renewable enjoy favor, becomes a kind of main textile materials.Reactive dyestuffs are because chromatogram is complete, cheap, and it is effective to print and dye, and technique is simple, easy and simple to handle, clean environment firendly, becomes the first-selected dyestuff of natural fabric dyeing and printing.As everyone knows, when dying cellulosic fibre with reactive dyestuffs, there is quite a few dyestuff when not forming covalent linkage with fiber, just to be hydrolyzed, and there is the partial hydrolysis dyestuff to be adsorbed to fiber surface, because a little less than the adsorptive power of hydrolised dye and fabric, colour fastness is low, namely causes textile loose colour.In order to improve the dyefastness of reactive dyeing thing, must be with hydrolised dye eccysis from the fiber, this just needs to use active dye detergent.Usually use the basic soap lotion, the cloth cover pH value is 10 ~ 11 in bathing when soaping, and is alkalescence, and scission of link easily occurs reactive dyestuffs when high temperature is soaped, so after the reactive dyestuffs alkali fixation, must be through three washings, and just can enter to soap to bathe after making the cloth cover pH value near neutrality and carry out soap boiling.Given this, we have developed, and a kind of to have the anti-contamination ability of washing strong, and can stablize the acid scouring agent of pH value effect.Use this acid scouring agent can reduce by one washing step with in the weak acid and operation, alleviate the pressure of sewage disposal, water saving reaches corresponding washing requirement simultaneously.
Summary of the invention:
Goal of the invention: for the defective that prior art exists, the invention provides that a kind of to have the anti-contamination ability of washing strong, and can stablize the preparation method of the acid scouring agent of pH value effect.
Technical scheme: for achieving the above object, the present invention by the following technical solutions: a, add successively fatty alcohol-polyoxyethylene ether AEO-15 in the reactor of 1000ml, PEG-200 and water are warming up to 40 ~ 70 ℃, stir 0.5 ~ 1 hour, make its dissolving; B, in the solution that step a obtains, add successively quantitative copolymer of maleic anhydride and acrylic acid, diethanolamine, water stirred 0.5 ~ 2 hour at 50 ~ 80 ℃, made solid content and be 28% acid scouring agent product.
Raw materials used mass fraction is:
Fatty alcohol-polyoxyethylene ether AEO-15:10 part
PEG-200:20 ~ 45 part
Copolymer of maleic anhydride and acrylic acid: 125 ~ 200 parts
Diethanolamine: 10 ~ 50 parts
The preparation method of described a kind of reactive dyestuffs acid scouring agent, fatty alcohol-polyoxyethylene ether AEO-15:PEG-200: copolymer of maleic anhydride and acrylic acid: diethanolamine is mass ratio 1:2 ~ 4.5:12.5 ~ 20:1 ~ 5.
According to above technical scheme, can realize following beneficial effect: compared with prior art, the present invention has the following advantages: acid scouring agent that the present invention obtains, it is strong to have the anti-contamination ability of washing, and can stablize the pH value effect, and can reduce by one washing step with in the weak acid and operation, alleviate the pressure of sewage disposal, water saving reaches corresponding washing requirement simultaneously.
