Abstract
The present invention is the newest fruits of lubricant coating used in die casting, comprises pressure-type water-based paint and presses chamber, pistons special grease paint.
The high temperature lubricating of water based paint is better than domestic and international similar products, and grease paint also is better than all kinds of oil-based paints of pressing chamber, piston to use at present.The present invention's coating is used for aluminium, magnesium, zinc alloy pressure casting, and isolation is strong, and high temperature lubricating is good, prevent the foundry goods sticking to mould, pull, distortion and piston, pressure chamber jam, reduce foundry goods stain and pore, reduce environmental pollution, reach the minimizing waste product, the purpose of boosting productivity.
Description
Technical field: the die mould (die cavity, core), pressure chamber, piston and the local difficult slip coating that divides the mould place that are applicable to aluminium, magnesium, zinc alloy pressure casting.

The composition of the present invention and domestic and international similar series, prescription, performance, effect are all inequality, and manufacture method is also inequality.
The purpose of invention: solve the sticking to mould that the die mould chemical affinity causes effectively, mechanical friction causes foundry goods demoulding difficulty, pulls, is out of shape.Lube pistons, pressure chamber prevent blocked portion effectively, improve the life-span.Increase substantially casting quality and production efficiency, particularly reduce environmental pollution.It is healthy and carry out production strictly in line with rules and regulations to help the workman.
It is that DFS-1 type and stearate grease paste lubricant coating used in die casting are two kinds of coating of DFY-1 type that the present invention comprises the water base lubricant coating used in die casting of oil-in-water type lipids, and its function and purposes are different.Be used for aluminium, magnesium, zinc alloy pressure casting die mould, piston, pressure chamber and the local difficult slip coating that divides the mould place.
The present invention reaches by the following technical programs:
(1) DFS-1 type: be the water base lubricant coating used in die casting of oil-in-water type lipids.Main as aluminium, magnesium, the demoulding of zinc alloy pressure casting die mould, lubricated, barrier coating.Adaptability is widely arranged, and being used in die casting producer mask large-scale, complex appearance has high temperature lubricating ability and high temperature demoulding ability, can prevent sticking to mould effectively, pull and casting deformation.Gas forming amount is few, significantly reduces environmental pollution, reduces bleb, and cast(ing) surface is bright and clean, clear, no packing phenomenon.Improve product percent of pass and productivity ratio effectively.
Its main compositing formula:
Stearic acid: 3-8%
Beeswax (or Chinese wax): 3-8%
White carbon: 0.5-1.5%
Silicone oil: 0.5-1.5%
Oil emulsion: 8-15%
Polyvinyl alcohol: 0.5-1%
All the other: water
The preparation method:
Beeswax (or Chinese wax) is emulsifying agent with the odium stearate, becomes the soap method to make emulsion with moment, is the slip coating base-material.
Chemical equation:
The filler white carbon is to carry out following reaction simultaneously with waterglass in the following formula course of reaction:
White carbon (the SiO that the following formula reaction obtains
2), extremely trickle, the light weight of particle, surface area and decentralization be big, mechanical strength and anti-tear index height are desirable reinforcing agent of slip coating and high-temperature lubricant.
Add modifying agent again, make the water base slip coating of uniform and stable emulsus through homogenizer or agitator.
Outward appearance: milky, neutrality, nontoxic, safe, do not burn.
Use: 5-15 times of dilution, manual or automatic spraying all can.
(2) DFY-1 type: be stearate grease paste lubricant coating used in die casting.Be applicable to die casting pressure chamber, piston and local difficult lubricant, the interleaving agent that divides mould place's use.
This coating can be carried hyperbaric chamber, piston life effectively, prevents obstruction, stuck piston, plays lubrication.Can also prevent that the local difficult mould place sticking to mould that divides from pulling.Production is carried out smoothly, boosted productivity, gas forming amount is low, reduces environmental pollution.
Its main compositing formula:
Barium stearate (or calcium): 25-35%
White carbon: 2-5%
Silicones: 1-2%
Beeswax or Chinese wax: 3-5%
Lubricating oil: all the other
The preparation method: barium stearate (or calcium) and white carbon are fat base slip coating base-material, and chemical reaction is as follows:
The product of above-mentioned reaction through removing moisture content and salt, is the slip coating base-material.Add modifying agent and lubricating oil again, make grease lubrication coating through stirring.
Outward appearance: white paste, neutrality, nontoxic, nonflammable.
Use: manual brushing or spraying automatically after diluting.
The present invention has the following advantages:
One, with relatively the possess skills characteristic of advanced person, novelty, original creation of present domestic various lubricant coating used in die casting.High temperature lubricating and release property are good, and foundry goods is bright and clean, gas forming amount is few, free from environmental pollution (carries out CO through environmental administration to the air of production scene; SiO
2Content measuring meets national regulation) etc. superiority.
Two, compare with the similar products that Japan, the U.S., Italy, Switzerland produce and also have certain advantage, high temperature lubricating and demolding performace are good, and manufacturing process advanced person is with low cost.DFS-1 type slip coating.Performance is through the test of machine tool institute, Guangzhou, and domestic and international various lubricant coating used in die casting was once tested by this institute, and certain comparativity is arranged.High temperature lubricating temperature t and coefficientoffriction (200-400 ℃) and at four-ball test aircraft measurements last non seizure load P
B, grinding defect diameter d
B, sintering load P
D, underload wearing and tearing d
30 20Its result's contrast sees the following form:
Realize the best form of the present invention: organize professional production, promote the use of or technology transfer.
Claims (2)
