Problems solved by technology

[0003] At present, in the vulcanized shoe manufacturing industry, the treatment agents used to produce vulcanized shoes are mainly solvent-based treatment agents. Solvent-based treatment agents use a large number of solvent-based products, polluting the environment, wasting resources, and affecting the health of shoe factory workers; water-based treatment Although the agent is environmentally friendly and saves resources, it is very limited in the vulcanized shoe industry. The main reason is that the water-based treatment agent has the following problems:
The heat resistance of the water-based treatment agent is not good, causing the toe cap to be easily exploded and drawn due to heat (the vulcanization temperature range is 90-115°C, the vulcanization pressure is 0.3±0.02Mpa, the vulcanization time is 75±15min, and the toe cap with high tension It is often prone to thermal

Abstract

The invention discloses a water-based treatment agent for vulcanized shoes and a preparation method thereof. The water-based treatment agent for vulcanized shoes is dedicated for processing vamp materials for the vulcanized shoes and comprises the following components in parts by weight: 80-120 parts of water-based polyurethane dispersion, 0.1-0.5 part of cosolvent, 0.1-0.5 part of hydrolysis-resistance agent, 0.2-0.5 part of defoamer, 3-10 parts of adhesive force accelerator and 0.2-0.5 part of thickener. The water-based treatment agent for vulcanized shoes, which adopts the system, has the advantages of stable system, good heat resistance, high bonding strength and high drying speed, is easy to coat and can be better applied to the production of vulcanized shoes.

Description

technical field [0001] The invention relates to a treatment agent for shoes, in particular to a water-based treatment agent for vulcanized shoes and a preparation method thereof. Background technique [0002] In the shoe industry, shoe treatment agents play an extremely important role. The surface states of shoe materials are various and varied. In addition to various attachments, the surface polarity and chemical state are also different. Generally speaking, if no treatment agent is used to change the surface chemical state of these bonding surfaces, it is difficult to achieve the desired bonding effect, because any kind of adhesive only has good "wetting" and "wetting" for certain materials Affinity" effect, but poor "affinity" for another type of material. If these shoe materials to be bonded can be treated with a treatment agent before gluing, the "pollution" physically adhered to the surface can be effectively removed, and more importantly, it can be treated by attachi...
