DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a laminate formed by laminating and molding a plurality of glass fabrics using a thermosetting resin as a binder, and more specifically,
The present invention relates to a laminate using glass fabric as a reinforcing base material, which has excellent dimensional stability, mechanical strength, electrical properties, heat resistance, and chemical resistance, as well as particularly cold punching workability.

Conventionally, glass fabric has been mainly used as a reinforcing base material for electrical insulating boards or copper-clad laminates for printed circuits used in electronic devices, telecommunications equipment, etc. that require extremely high quality. This is because laminates based on glass fabric are extremely excellent in properties such as dimensional stability, mechanical strength, electrical properties, heat resistance, and chemical resistance, which are most required in this field. However, laminates made of glass fabric as a base material have the disadvantage that cold punching is difficult and machinability such as drilling is extremely poor.

On the other hand, laminates using glass fabric, glass paper, glass strand mat, glass fiber, etc. as the base material are also widely known. These substrates have a weak reinforcing effect in the plane direction compared to glass fabric substrates, so although they have excellent machinability of laminates, especially cold punching, on the other hand, they are given top priority. The properties of dimensional stability, mechanical strength, electrical properties, and chemical resistance are considerably inferior to those of glass fabric substrates. Furthermore, laminates using glass nonwoven fabrics containing inorganic fillers, glass paper, etc. as base materials have been proposed for the purpose of improving mechanical strength and other properties. Although this laminate is said to have excellent cold punching properties, and slight improvements in mechanical strength and electrical properties are observed, properties such as dimensional stability and heat resistance are still unsatisfactory.

In addition, glass fabric is used as the base material for both surface layers of the laminate.
A so-called composite type laminate using a glass nonwoven fabric containing an inorganic filler, glass H-i4-, etc. as the base material of the intermediate layer has been devised. Although these laminates have excellent cold punching properties and excellent performance in terms of strength, mechanical strength, electrical properties, heat resistance, etc., they do not have any properties other than cold punching properties. At present, the properties are far inferior to those of laminates made of glass fabric as a base material. In particular, these laminates have poor dimensional stability not only in the plane direction but also in the z-axis direction, resulting in fatal defects such as twisting and breakage of through-hole plating. Furthermore, it cannot be said that the heat resistance and chemical resistance are satisfactory.

The present inventors have developed properties such as dimensional stability, mechanical strength, electrical properties, heat resistance, and chemical resistance that are almost comparable to conventional laminates using only glass fabric as a base material. As a result of intensive research to develop a glass fabric reinforced laminate that has excellent cold punching properties, we found that the strength of the threads constituting the base glass fabric was suppressed. The inventors have discovered that the above objectives can be achieved, and have completed the present invention.

In the present invention, "the tensile strength of the glass threads constituting the glass fabric" refers to the tensile strength of the glass threads constituting the glass fabric immediately before lamination molding using a thermosetting resin as a binder. In other words, in general, a glass fabric is made by interweaving warp and weft yarns, but glass fabrics have a binder (sizing agent) attached to them that is used as a binding agent during spinning of raw yarn and warping of warp yarns. After weaving, the size is usually removed by heat cleaning or washing. Furthermore, the desized glass fabric is usually coated with a coupling agent to strengthen the bond with the thermosetting resin (for example, a coupling agent such as a silane compound is used to strengthen the bond with the epoxy resin). After surface treatment, it is laminated and molded.

The tensile strength of the glass threads constituting the glass fabric, which is the base material of the laminate of the present invention, is 10% with the warp and weft immediately before being used for lamination molding using a thermosetting resin as a binder.
Must be less than gf/lax and the sum of both is 15 gf/
l@x, which is considerably lower than conventional glass woven substrates. As described above, although the tensile strength of the threads of the glass fabric base material of the present invention is slightly lower than that of the threads of the conventional glass fabric base material, the glass fabric base material laminate of the present invention It has characteristics such as dimensional stability, mechanical strength, electrical properties, heat resistance, and chemical resistance with almost no engagement compared to the base material laminate, and it is different from the conventional glass fabric base material laminate. It is surprising that the material exhibits far superior cold punching workability in comparison.

Generally, the tensile strength of glass thread varies depending on the amount of glue attached, the amount of coupling agent attached, and the temperature and time of heat cleaning, but in order to obtain a low-strength glass fabric like the one used in the present invention, requires special strength reduction treatment. Other methods of reducing strength include heat cleaning at a high temperature of 400°C or higher for a relatively long period of time, or immersion in an acid or alkali solution, but the former method requires a long period of time in a special furnace. Because of the processing, it is not industrially advantageous, and there is also the problem that unscrupulous methods adversely affect the electrical properties of the glass fabric base laminate that is finally obtained. A particularly preferred strength reduction treatment method is
This is a method in which a dilute solution of a specific silane compound such as tetraalkoxysilane, trialkoxysilane, or dialkoxysilane is applied to a glass fabric, and the glass fabric is heated with a trace amount of the silane compound attached. By such a method, it is possible to reduce the strength very effectively and industrially.

上述の特定のシラン化合物の適用は糊剤を除去するため

It is desirable that the specific silane compound described above be applied prior to heat cleaning to remove the sizing agent.

This application can be done by immersing the glass fabric in a dilute solution of the silane compound or by spraying the dilute solution onto the glass fabric. It has a positive correlation with the amount of reduction, and the tensile strength of the glass thread can be arbitrarily controlled by changing the amount applied and the heat cleaning heating temperature.

Note that the lower limit of the tensile strength of the glass threads constituting the glass fabric is not particularly limited as long as the dimensional stability, mechanical strength and other properties of the resulting laminate and compatibility in the lamination molding process are satisfied. However, the tensile strength of the warp is about 5
It is desirable that it is equal to or greater than gf/lex.
