Abstract

PURPOSE:To improve the varnish impregnating properties and enhance a dimenstional stability, etc. of a laminate, by making a base material for laminate pass through the press rolls in the condition of being immersed in the varnish within a varnish tank, then moving it contacting squeeze rolls. CONSTITUTION:After the tension of a base material for laminate 1 is adjusted by the quantity of surface material and the number of rotation of a brake roll 2, it is passed through a plurality of press rolls 4, 4', 4'' in the condition of being immersed in a varnish within a varnish tank 3, the air in the base material is exchanged with the varnish, the base material is enough impregnated with the varnish and the impregnation amount of the varnish is adjusted by squeeze rolls 5. The arrangement of the press rolls in the varnish tank may be any of a horizontal, vertical, inclined type, etc. and does not be specified particularly. The condition used for the manufacture of an ordinary prepreg is used on drying, take-up, cutting, etc. of the base material impregnated with the varnish.

。[Detailed Description of the Invention] The present invention is a book about a method for impregnating varnish into a laminate substrate, and its purpose is to improve the varnish impregnation property into the laminate substrate, and to improve the formability and dimensions of the laminate. Conventionally, when producing prepreg by impregnating a laminate base material with varnish and drying it, it is generally done by two-step impregnation treatment with an undercoat varnish and a topcoat varnish, or by using one dip roll. In the past, a method was used to adjust the amount of adhesion using a squeeze roll, but in each method, the varnish impregnation into the laminate base material was insufficient, resulting in a prepreg that contained air, which caused air to be added during laminate molding. High-pressure molding was required to release the material, which caused the laminate to warp and twist.

−板を得ることができる本のである。The uninvented method solves the above-mentioned drawbacks by using woven fabrics, non-woven fabrics or mats, which are made from inorganic fibers such as glass and asbestos, organic synthetic fibers such as polyester, polyamide, polyvinyl alcohol, and acrylic, and natural fibers such as cotton sieves. A laminate substrate such as paper or a combination of these substrates is mixed with phenol resin, cresol resin, epoxy resin, unsaturated polyester resin, melamine resin, polyimide resin, polysulfone, 1) butadiene, fluorinated resin in a varnish tank. , polybutylene terephthalate, polyether ether ketone, etc. alone, modified products, or mixtures, etc., are soaked in a varnish containing a solvent such as water, methyl alcohol, acetone, cyclohexanone, styrene, etc. as required, and then passed through a pressure roll. Since the air is moved in contact with the squeeze roll, the air present in the laminate base material is pushed out by the dip roll installed in the wafer λλ, resulting in a prepreg fully impregnated with varnish, which eliminates the need to squeeze out the air during laminate forming. Since there is no need for high pressure molding, there is no need for warping or twisting.

A plurality of pressure rolls 4 are immersed in varnish in a
4/ and 4/I to replace the air in the base material with varnish so that the base material is sufficiently impregnated with 2 g of varnish, and then the squeeze roll 5 is used to adjust the amount of varnish deposited.
