Abstract
What the present invention relates to is the glass mold releasing agent, is made up of solid lubricant, binding agent, dispersion agent, defoamer and water.The weight percent of graphite and boron nitride is 2: 1～6: 1, and content is 10～30% in releasing agent, adopts this kind releasing agent to avoid making coating with oil, and the pollution that carrier causes is improved the quality of products and yield rate, reduces cost.
Description
What the present invention relates to is a kind of demolding agent of glass forming mold.
Traditional demolding agent of glass forming mold is to adopt the derivative of mineral oil or oil to make carrier to add graphite and make coating, will smear once to mould every 5～10 minutes, to reach the effect of lubricating release, this releasing agent produces a large amount of smog after meeting high temperature, cause environmental pollution, the impurity that is deposited on die surface is easily sneaked into and is made die surface produce the uneven quality product that influences in the glass metal.The solid lubricant that United States Patent (USP) 3783013 adopts is a boron nitride, and its content costs an arm and a leg up to 47～88%.United States Patent (USP) 3994847 adopts graphite as solid lubricant, and it is high temperature resistant and antioxygen property is poor, influences die life.United States Patent (USP) 4039337 adopts graphite and boron nitride, and as binding agent, but because water-soluble silicate is crisp, poor with substrate adhesion, easy to crack in use with water-soluble silicate.
Purpose of the present invention is exactly in order to prolong glass mold work-ing life, and the easily demoulding reduces cost, and improves stripping result, avoids environmental pollution, improves labour intensity.
The present invention adopts graphite and boron nitride to make solid lubricant, the weight ratio that it is characterized in that graphite and boron nitride is 2: 1～6: 1, content in releasing agent is 10～30%, binding agent adopts the two hydrogen aluminium of water-soluble phosphoric acid, its content is 20～40%, dispersion agent is 0.1～1%, and defoamer 2～5% and water are formed.Dispersion agent can be selected a kind of from sodium methylene bis-naphthalene sulfonate, aliphatic alcohol polyethenoxy methyl-monosilane, desugar sodium lignosulfonate, Sodium hexametaphosphate 99 and trisodium phosphate.Defoamer can from low-carbon alcohol, select in carbon alcohol, fatty acid, tbp and the propylene glycol polypropylene-polyethylene ether a kind of.After above-mentioned raw materials prepared by weight percentage, make demolding agent of glass forming mold through 6 hours ball millings.
The invention will be further described below in conjunction with example:
Example 1
Releasing agent consists of graphite 11.8%, boron nitride 5.9%, the two hydrogen aluminium 20% of phosphoric acid, dispersion agent 0.17%, defoamer 3.4%, water 58.73%.Raw material is packed in the ball grinder, promptly make through 6 hours ball millings.
Example 2
Releasing agent consists of graphite 16.8%, boron nitride 3.2%, and the two hydrogen aluminium 30% of phosphoric acid, dispersion agent 0.2%, defoamer 3.4%, water 46.4% is packed material in the ball grinder into, through 6 hours ball millings.
The present invention compared with prior art, the demoulding is easy, has improved labour intensity, avoids polluting, product brightness height improves yield rate, reduces cost.
Claims (4)
