Abstract
The invention discloses a composition for a polyurethane stripping wheel and relates to the field of chemical technology. The composition comprises the following components by weight: 10-30 kg of linear polyethylene, 50-65 kg of polyester polyol, 10-15 kg of titanium dioxide, 4-6 kg of a vulcanizing agent, 4-6 kg of an antioxidant, 4-6 kg of a dispersant, 5-15 kg of emulsifier, 25-35 kg of pure MDI and 2-4 kg of tung oil. The service life of the stripping wheel prepared from the composition disclosed by the invention, compared with the rubber stripping wheel in the prior art, is 5-6 times of the service life of the rubber stripping wheel, the stripping wheel is easily molded and fast dried and the manufacturing cost is low.
Description
Technical field
The present invention relates to chemical technology field, be specifically related to a kind of polyurethane stripping wheel composition.
Background technology
Stripping wheel belongs to a kind of extra-fine grinding machinery accessory, generally more than 800 orders.In the middle of prior art, be all to use rubber stripping wheel substantially, the friction dynamics needing due to extra-fine grinding is larger, wear resistance for stripping wheel requires just higher, but its wear resistance of the stripping wheel of existing this quality of rubber materials is not very good, in process of lapping, need frequent replacing, cause labour intensity large, production efficiency is low, and cost is also very high.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of composition simple, the polyurethane stripping wheel composition of long service life.
Technical problem to be solved by this invention realizes by the following technical solutions:
A polyurethane stripping wheel composition, is comprised of the component of following weight,
The optimum weight of each component is
The invention has the beneficial effects as follows: stripping wheel prepared by the present composition is compared its work-ing life with rubber stripping wheel of the prior art be 5 to 6 times of rubber, is easy to moulding, fast drying, low cost of manufacture.
