Abstract

The invention relates to a pressure-sensitive glutinous composition which uses glutinous rice flour as a raw material and application thereof, which belong to the product and technology of environment-friendly hydrophilic pressure-sensitive adhesive. The glutinous rice flour, water, a liquid plasticizer at room temperature and a modifier are mixed, heated and cured to form the pressure-sensitive adhesive composition with application of tearability and adhesion; the glutinous rice flour is flour of sticky rice, glutinous corn, large glutinous millet, small glutinous millet and glutinous sorghum rice and one or a mixture of several of starch of the glutinous rice and modified starch. The composition can be combined with various substances, drugs with different types and the like to prepare various pastes, can be widely used in a transdermal administration system, an iontophoresis system, wound treatment, a biological medical electrode and other equipment and systems needing pressure-sensitive adhesive and is in particular suitable for the application of a traditional Chinese medicine transdermal administration preparation.

Description

technical field

[0001] The invention relates to a pressure-sensitive adhesive composition using glutinous rice flour as a raw material and an application thereof, belonging to environment-friendly hydrophilic pressure-sensitive adhesive products and technologies. Background technique

[0002] At present, the pressure-sensitive adhesives (PSA) used in self-adhesive tapes and medical fields, especially the pressure-sensitive adhesives (PSA) of transdermal drug delivery systems (TDDs), are usually polysiloxane (such as: polydimethylsiloxane, polybisphenyl silicones and blends of silicones), polyisobutylene (PIB), polyacrylates, acrylic acid and acrylate copolymers (such as copolymers of acrylic acid and 2-ethylhexyl acrylate or isooctyl acrylate material), and neoprene (polychloroprene). All of these pressure-sensitive adhesives are chemically synthesized products, which generate large pollution and energy consumption during the production process. At the same time, these hydr...
