Abstract
An amino resin composition for use in cleaning a fouled surface of a mold for molding a curable resin molding material, which contains a metallic soap and a nonmetallic fatty acid lubricant.
Description
Affiliated technical field
The present invention relates to when the curable resin mold plastics of molding, remove the amino resin composition of residual dirt from die surface.The present invention relates more specifically to have good mould cleaning function and the amino resin composition of good characteristic in blocks under condition of moulding widely.
Background technology
Recurrent in the past is that at the layered product with curable resin such as epoxy resin mold sealing, during as integrated circuit, when the molding last very long, the inner surface of mould can be dirty.When molding also continues, just made dirty in the surface of sealed mould molding product.And the layered product of sealing adheres on the mould, can not carry out thereby moulding process is become.Therefore, cleaning mold periodically.For this purpose, a method has been proposed, wherein mould at molding after the hundreds of grain moulding compound, clean to remove residual dirt by several molding spatter property resins.
For example, in the open 52-788 of Japan's special permission, the method on a kind of cleaning mold surface has been proposed, wherein the molding curable resin when (not comprising amino resins) the residual dirt of die surface carry out molding with spatter property material (containing amino resins) and remove as Main Ingredients and Appearance.In this patent, the mould clean resin that comprises amino resins, organic material such as paper pulp and tree end and/or inorganic material such as silica and calcium carbonate and lubricant is disclosed.And the open 64-10162 of Japan's special permission has disclosed a kind of mould clean resin, and it comprises the cocondensation resin of a kind of amino resins and a kind of phenol resin and has the mineral dust of new Moh's scale number 6 to 15.
These mould clean resin compositions are generally to use with the sheet of the identical size of plastics.Molding makes the sheet temperature become 90 ℃ to 110 ℃ by preheating to carry out.By this way, mould clean resin composition is filled to the whole zone of mould.When mould clean resin composition solidified, it took up residual dirt and the surface of cleaning mold from the surface of mould.
Recently, in order to satisfy unattended and cleaning molding requirements of one's work, the automatic molding machine of curable resin is developed, and automated molding work becomes universal.Use automatic molding machine, the sealed mould molding product is as IC ' s and LSI ' s, with several little mould moldings to tens chambeies are arranged.Used sealing resin is to have the small pieces supply of about 5mm to about 40mm diameter.
Above-mentioned automatic molding machine has adopted the molding methods of automatic repetition series of steps, and these steps comprise in pot supplies small pieces, and molding small pieces in the preheating in pot take out layered product then automatically.
And, at IC ' s, in the fields such as LSI ' s, tend to higher integrated level, the thinner profile and the trend of surperficial substrate raise.Thereby layered product become more diversified, and the small pieces with all size use according to required layered product.And the size of mould clean resin composition reduces according to the sealing resin small pieces.Like this, the small pieces with mould clean resin composition of all size are required.
So, be described in the Japanese known resin combination of this class of speciallyying permit among the open 52-788 is used to clean automaton so far by the formation strip mould.
Yet when this class spatter property resin combination in being described in the open 52-788 of Japan's special permission formed small pieces, the small pieces of Xing Chenging were difficult to release from mould like this.Therefore, when small pieces can be produced the sound of creaky voice when mould is released,, increased the rate of abandoning of small pieces on small pieces such as breaking or error such as breach is easy to take place.And because the curing rate of spatter property resin combination is very low, when being molded into low temperature and carrying out, the spatter property resin combination bubbles, thus when automated molding when low temperature carries out, the spatter property resin combination can not be used for cleaning mold.When the spatter property resin combination in being disclosed in the open 64-10162 of Japan's special permission was used to form small pieces, the rate of abandoning that forms small pieces was too high.Because the spatter property resin combination shows high solidification rate, thereby when being molded into low temperature and carrying out, the spatter property resin combination is cleaning mold effectively.Yet it can not be at the mould of high-temperature cleaning automatic molding machine, though with common consumption the twice cleaning mold also be like this.
And conventional spatter property resin combination is determined from the large stretch of angle of molding or shortening cleaning time that promotes of preheating usually.Therefore, when small pieces when the composition identical with sheet forms, show that the scope of the condition of moulding of good clean-up performance narrows down because small pieces need be used the non-pre-hot-moulded of automatic molding machine, different fully with the condition of moulding of large stretch of molding.And when cleaning was carried out under the condition of moulding of the behavior that generation is not too cleaned, the operator must increase the grain number of spatter property resin.
Therefore, people long for always increases the amount that is contained in lubricant in the spatter property resin combination, as specially permit the composition described in the open 52-788 in Japan, to increase the output in the sheet metallization processes.Yet when the amounts of lubrication in being contained in the spatter property resin combination increased, the problem of generation was lubricant outflow itself and causes the mould fouling that wherein under the condition of moulding that not too cleans behavior, the grain number of spatter property resin combination must increase.
Such needs exist: the mould clean resin composition that has good characteristic in blocks and good sanitary characteristics under condition of moulding widely.
Of the present invention open
The inventor carried out big quantity research concurrent existing when show good lubricating effect, and the nonmetal fatty acid lubricant of resin with good miscibilty and good heat endurance be used as and do not increase the amount of lubricant in the sheet metallization processes and when increasing the lubricant of productive rate, it is good that the sanitary characteristics of spatter property resin combination can keep, and its sheet characteristic can be modified, and shares the flowability of spatter property resin combination and the metallic soap of mould separating is used as lubricant during molding.
The present invention just finds based on this class.Therefore, the invention provides the amino resin composition of removing residual dirt when the curable resin of molding from the surface of mould, it comprises amino resins, metallic soap and nonmetal fatty acid lubricant.
