Abstract
The invention discloses a dedusting agent. The dedusting agent mainly comprises 25-35 wt% of tung oil, 1-5 wt% of emulsifier and 60-75 wt% of water. The dedusting agent can be used for inhibiting the generation of flying dust in the production of friction material mixing materials. Compared with the prior art, the invention can effectively solve the problem of dust floating pollution in the production of the friction material, does not influence the product quality, and does not need to increase special dust removal equipment.
Description
Technical Field
The invention belongs to the field of friction material production, and particularly relates to a dust remover for inhibiting dust generated in the production of friction material mixing.
Background
The friction material mainly comprises a resin adhesive, a fiber reinforced material and a filler, and a large amount of dust pollution can be generated in the production process of mixing the resin adhesive, the fiber reinforced material and the filler. The flying dust floats in the air and enters the human body through the respiration of the human body, which causes damage to the health of the human body.
Disclosure of Invention
The invention provides a dedusting agent for overcoming the problem that the existing friction material generates raised dust during material mixing.
In order to achieve the purpose, the technical scheme adopted by the invention is as follows:
a dedusting agent is characterized in that: the dedusting agent mainly comprises 25-35 wt% of tung oil, 1-5 wt% of emulsifier and 60-75 wt% of water.
Preferably, the dedusting agent consists of 30 wt% of tung oil, 3 wt% of emulsifier and 67 wt% of water.
The preparation method of the dedusting agent comprises the following steps:
mixing an emulsifier and water, and heating to 50-60 ℃;
then tung oil is added and mixed evenly to obtain the dedusting agent.
A method for preventing dust emission in the production of friction materials is characterized in that 2-5 wt% of the dust remover is added during the mixing of the friction materials.
Compared with the prior art, the invention can effectively solve the problem of dust floating pollution in the production of the friction material, has simple use and operation, does not influence the product quality, and does not need to increase special dust removal equipment.
Detailed Description
The present invention will be described in further detail with reference to examples.
Example 1
Preparation of dedusting agent
30 wt% of tung oil
3% by weight of an emulsifier
67 wt% of deionized water
Adding the emulsifier into a reaction kettle according to the proportion, adding deionized water, heating to 50-60 ℃, and stirring for 30 minutes.
Then adding tung oil in proportion, keeping the temperature at 50-60 ℃, stirring for 60 minutes, cooling to room temperature to obtain the dedusting agent, and placing into a container for later use.
Use of dedusting agents
The dust remover is added into the conventional friction material mixing production according to 2-5 wt% of the mixing, and other massage friction materials are operated in the conventional production process.
The same amount of added tung oil was used for comparison.
The comparative experiment shows that compared with the single tung oil, the dust remover has obvious dust removal effect and long dust suppression effect maintaining time.
Example 2
The dedusting agent comprises the following raw materials:
25 wt% of tung oil
3% by weight of an emulsifier
72 wt% of deionized water.
The procedure was as in example 1.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
