preparation example Construction

[0032] The preparation method of the laundry sheet of the present invention, such as figure 1 As shown, the following steps may be included:

[0033] S1: Weigh the water-soluble copolymer, heat it up and dissolve it in water to obtain the first system; specifically, according to the proportion of the formula, measure a certain amount of deionized water in a reaction container, and then slowly heat up the temperature while raising the temperature While adding a certain amount of water-soluble copolymer, after raising the temperature to 80-99° C., and then keeping the temperature for a period of time until the copolymer is completely swollen and uniform, the first system is obtained.

[0034]S2: Dissolve the surfactant and the auxiliary material in the first system in turn to obtain the second system; specifically, when adding the surfactant and the auxiliary material to dissolve, each time a raw material is added It must be ensured that it is completely dissolved before adding...

Embodiment 1

[0039] In this embodiment, the components of the laundry tablet include: polyvinyl alcohol, surfactants and auxiliary materials, wherein the surfactant includes potassium lauryl sulfate and coconut oil fatty acid diethanolamide, and the auxiliary materials include film-forming agents, grease, Moisturizing agent, pigment and essence, film forming agent is CMC, oil is polyether modified silicone oil, moisturizing agent is glycerin. The ratio of each component is shown in Table 1 below.

Abstract

The invention provides a laundry sheet and a preparation method thereof. The laundry sheet comprises the following components: a water-soluble copolymer, a surfactant and auxiliary materials, whereinthe surfactant comprises potassium alkyl sulfate. The invention provides the laundry sheet and the preparation method thereof. The laundry sheet adopts a water-soluble copolymer as glue and adopts potassium dodecyl sulfate as an ionic surfactant, so that the proportion of surface activity in the laundry sheet is higher and the cleaning and decontamination effect is better.

Description

technical field [0001] The invention belongs to the field of chemical industry and relates to a laundry tablet and a preparation method thereof. Background technique [0002] Washing powder or laundry liquid is the most commonly used laundry detergent in daily life, but generally more or less additives such as phosphorus are contained in washing powder or laundry liquid. On the one hand, the discharge of washed wastewater into the environment will cause environmental pollution. [0003] Laundry tablets are a new type of ecological washing product. Compared with traditional washing powder or laundry liquid, laundry tablets can quickly decompose and dissolve when exposed to water, release nano-scale clean molecules, and purify the impurities deposited on clothes more deeply and thoroughly. Stubborn stains greatly improve the decontamination ability of the product, and laundry tablets generally do not contain harmful additives such as phosphorus, which neither hurts hands nor ...
