Problems solved by technology

However, due to the low softening point of rosin resin, it is easy to soften at room temperature and cause hydrocolloid to stick to other objects. Usually, there will be different degrees of glue overflow at room temperature or even in an environment of 40°C; at the same time, it does not have antibacterial and anti-inflammatory functions during use. Unable to meet current market demand

Abstract

The invention relates to antibacterial and high-temperature-resistant hydrocolloid and a preparation method thereof. The antibacterial and high-temperature-resistant hydrocolloid comprises raw materials in parts by weight as follows: 15-48 parts of thermoplastic elastomer, 1-8 parts of an antioxidant, 10-25 parts of a plasticizer, 18-39 parts of a tackifier, 18-39 parts of a thickening agent and 1-15 parts of honey. According to the antibacterial and high-temperature-resistant hydrocolloid, by means of optimization of related formula components, the hydrocolloid is prevented from overflowing in a long-term high temperature environment, can continuously keep good viscosity and can realize antibacterial and anti-inflammation effects in a using process, thereby solving troubles caused by hydrocolloid overflow in a daily using process of a user and being capable of preventing wound inflammation. The preparation method is simple to operate, the process is easy to control, and large-scale production is facilitated.

Description

technical field [0001] The invention belongs to the field of nursing after medical ostomy, and in particular relates to an antibacterial, high temperature resistant hydrocolloid and a preparation method thereof. Background technique [0002] At present, most hydrocolloids use rosin resin as a tackifier. However, due to the low softening point of rosin resin, it is easy to soften at room temperature and cause hydrocolloid to stick to other objects. Usually, there will be different degrees of glue overflow at room temperature or even in an environment of 40°C; at the same time, it does not have antibacterial and anti-inflammatory functions during use. Can not meet the current market demand. [0003] Therefore based on this, propose technical scheme of the present invention. Contents of the invention [0004] In order to solve the problems in the prior art, the invention provides an antibacterial, high temperature resistant hydrocolloid and a preparation method thereof. Th...
