Abstract
The invention relates to a coating combination, especially a coating used for producing hard alloy, adopting the following components in the proportion: graphite powder 20-40%, tween 4-8%, polyvinyl alcohol 0.2-1.0%, formaldehyde 0.05-0.5%, alumina powder 1-5%, water-soluble glue 0.1-1.0%, and distilled water 50-70%; it has the characters of strong adhesion, being easy to uniformly disperse as being coated, excellent anti-adhesive property to hard alloy product in the vacuum-sintering process, and its preparing process is simple, its cost is low, and it can strengthen the quality stability of the hard alloy products, beneficial to large-scale industrialized production of hard alloys, and its economic benefits are good.
Description
Technical field
The present invention relates to a kind of coating composition, especially a kind of coating that is used for CEMENTED CARBIDE PRODUCTION.
Background technology
As everyone knows, the used boat of vacuum sintering operation needs a kind of coating that prevents the sticking boat of product in the CEMENTED CARBIDE PRODUCTION process, fast development along with hard carbide industry, vacuum sintering technology progressively is widely used, the used release coating consumption of its boat is also increasing, and kind is also more and more diversified.In general, it is formulated by Graphite Powder 99, tween, sodium butadiene rubber, distilled water etc. producing the release coating that is adopted, but ubiquity coating is not strong to the sticking power of graphite boat, be difficult for during brushing being uniformly dispersed, non-stick property to hart metal product in the vacuum sintering process is good inadequately, and the easy and boat bonding of product causes serious carburizing of product or local carburization, cause serious product quality problem, and damage defective such as boat.
Summary of the invention
The objective of the invention is to overcome the deficiency of release coating commonly used, provide that a kind of blending process is simple, constant product quality, hard alloy vacuum sintering boat release coating that production cost is low.
Technical scheme of the present invention realizes that by following approach it is to adopt following component and proportioning to make: Graphite Powder 99 20～40%, tween 4～8%, polyvinyl alcohol 0.2～1.0%, formaldehyde 0.05～0.5%, aluminum oxide powder 1～5%, water-soluble glue 0.1～1.0%, distilled water 50～70%.
Compare with technology commonly used, the present invention has strong adhesion, be easy to during brushing be uniformly dispersed, in the vacuum sintering process to characteristics such as the non-stick property of hard metal article is good, and blending process is simple, and cost is low, uses it can improve the hart metal product quality of stability, help the large-scale industrial production of Wimet, good in economic efficiency.
Embodiment
Specifically describe embodiments of the present invention below, it is to adopt following component and proportioning to make: Graphite Powder 99 20～40%, tween 4～8%, polyvinyl alcohol 0.2～1.0%, formaldehyde 0.05～0.5%, aluminum oxide powder 1～5%, water-soluble glue 0.1～1.0%, distilled water 50～70%.
The tween that the present invention adopts is a tween 80.
Compound method of the present invention comprise raw material preparation, by than batching, stir.
1. raw-material preparation:
All raw materials are ready on request, and polyvinyl alcohol is needed to use the distilled water heating for dissolving in advance, make 5% the aqueous solution;
2. by proportion ingredient: strict by prescription requirement, the weight of each component that weighs with scale;
3. stir: various components stir under the dry type state earlier in the process for preparation, add distilled water then and adopt mechanical stirring 4 hours.
Three embodiment of the present invention are:
Embodiment 1: Graphite Powder 99 30%, tween 6%, polyvinyl alcohol 0.6%, formaldehyde 0.3%, aluminum oxide powder 3%, water-soluble glue 0.6%, distilled water 59.5%.
Embodiment 2: Graphite Powder 99 30%, tween 8%, polyvinyl alcohol 0.5%, formaldehyde 0.3%, aluminum oxide powder 3%, water-soluble glue 0.5%, distilled water 5 7.7%.
Embodiment 3: Graphite Powder 99 2 5%, tween 5%, polyvinyl alcohol 0.8%, formaldehyde 0.08%, aluminum oxide powder 3%, water-soluble glue 0.3%, distilled water 65.82%.
