[0003] CN1354234A discloses a tablet for laundry, which uses a phosphorus-containing builder, which will cause eutrophication of the water body and does not meet the concept of green and environmental protection life
CN101914415A discloses an effervescent detergent and a preparation method thereof. Its tablet disintegration system only utilizes the principle of effervescence, the principle is single, and the limitations are large, and there is no effective relationship between the acidic component and the alkaline component of the disintegrating agent. Barrier, the two are prone to react, or get wet and cause product failure
CN105154254A discloses an organic carbonate detergent and an instant laundry effervescent tablet, wherein ethylene carbonate is used as a raw material, but ethylene carbonate has serious irritation to eyes, respiratory system and skin, and is easy to cause harm to human health
CN1428410A discloses a laundry tablet detergent and its manufacturing method, wherein a water-insoluble but swellable polymer is used as a disintegrant, the disintegration time is fast, it can be quickly dissolved, and the radial fracture strength meets the requirements. However, the product has poor stability and is greatly affected by storage humidity
CN103966032A discloses an environment-friendly neutral concentrated tablet detergent, in which high-efficiency tablet-shaped dissociating agent acrylate is used, and combined with its swelling system, the dissolution rate of the tablet-shaped detergent is extremely fast, but its stability is not considered , it is not easy to store for a long time, and it is not easy to store in an environment with high humidity
[0004] In summary, the common disadvantages of existing laundry tablet products are: (1) contain chemical components harmful to the environment and human body; (2) the disintegrants all adopt the principle of effervescence, the system is single, and the dissolution time is long during use ; (3) The disintegrant is prone to failure, and the product stability is greatly affected by the storage humidity

Abstract

The invention discloses a laminated laundry detergent tablet and a preparation method thereof. The laminated laundry detergent tablet is prepared from, by weight, 5%-10% of a non-ionic surfactant, 15%-35% of an anionic surfactant, 3%-10% of an auxiliary washing agent, 0.1%-5% of an adhesive, 40%-60% of a disintegrating agent, 0.1%-5% of a laminating agent and 1%-5% of a solvent. The laminated laundry detergent tablet which is made from biodegradable materials is highly concentrated, low in consumption and high in detergence; by combination of an effervescence system and a polymer swelling system, high disintegration speed is realized; due to water-soluble laminates on surfaces of material particles, interaction or dampness of a disintegration agent can be avoided, requirements on a storage environment are lowered, and the shelf life is prolonged. The preparation method is completed under a normal-temperature normal-pressure condition, convenient, quick and simple in operation, free of special equipment, wide in application range and low in cost.

Description

technical field [0001] The invention belongs to the field of daily chemicals, in particular to a film-coated laundry tablet detergent and a preparation method thereof. Background technique [0002] With the development of the detergent industry, domestic daily chemical detergents are constantly being introduced. Among them, powdered detergents and liquid detergents have appeared successively in terms of laundry detergents. Powdered detergents are usually produced by high-tower spraying, which requires complex equipment and consumes a lot of energy; liquid detergents use water as a carrier, and ingredients such as surfactants are not stable in water. In today's era, the life philosophy of green environmental protection and low-carbon economy has gradually become the mainstream. The laundry detergent not only conforms to this life philosophy, but also makes up for the shortcomings of powder detergents and liquid detergents. Clothing tablet detergent is a high-density, precise...
