明性にすぐれた材料を用いた合せガラスに関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a laminated glass used for automobile windshields, building glass, etc., and more specifically, it has sufficient practical strength as an interlayer film, excellent processing workability, and transparency. This invention relates to laminated glass made of materials with excellent properties.

Although PVB (hereinafter abbreviated as PVB) is widely available, the films tend to viscous each other and cause so-called blocking. To avoid this, a powder such as sodium bicarbonate is generally sprinkled on top of the embossed surface during membrane processing.

さらには連続的な加工工程をとり得ることを開示した(
特願昭5S−80915)。しかしこの組成物において
はなお、逸散化物等の架橋剤を混線。In order to obtain an appropriate adhesion force, complicated steps such as adjusting the moisture content of the film are taken. In addition, the fact that heating and pressure is required in an autoclave in the final adhesion process with glass is undesirable from the perspective of process automation, etc. The present inventors have already developed ethylene-vinyl acetate as a new laminated glass material that has improved these drawbacks. By crosslinking a copolymer (hereinafter abbreviated as FiVA) while maintaining it above its crystal melting point, it has excellent transparency, sufficient practical strength, and has little blocking property during processing.
Furthermore, it was disclosed that continuous processing steps can be used (
Patent application Sho 5S-80915). However, this composition still contains crosslinking agents such as fugitives.

もたらすのである。There are restrictions on the adding temperature or the processing temperature when forming the composition into a film, and especially when using materials with a low melting index or materials containing vinyl acetate (hereinafter abbreviated as VA amount),
For materials with a thickness of less than 0.0 cm, it is difficult to form a uniform film unless the processing temperature is increased, and the pressure bonding temperature when clamping the film to glass also tends to be high. For example, when a composition is formed into a film by an extrusion method, an inflation method, a calendar method, a press method, etc., such an increase in processing temperature tends to cause scorch inside and outside the processing machine.
Particularly in processing machines, this not only results in material loss, but also requires disassembly and cleaning of the processing machine, resulting in huge losses in terms of both productivity and costs.

硬化性樹脂組成物をガラス板間に介在させてガラス板と
一体化し、該樹脂の融点以上の温度下で加熱しまたは光
照射して樹脂層を硬化させてなる合せガラスである。The present inventors took these points into consideration and as a result of intensive research, they found that adding a certain amount of plasticizer to the composition lowers the processing temperature, avoiding the above problems and at the same time reducing the The present invention was completed based on the discovery of the previously unknown fact that it is useful for improving transparency as a glass material and does not substantially impair impact resistance. That is, the present invention interposes between glass plates a heat- or photo-curable resin composition prepared by blending an ethylene-vinyl acetate copolymer with a plasticizer and peroxide or a plasticizer and a photosensitizer. It is a laminated glass made by integrating the resin layer and curing the resin layer by heating at a temperature higher than the melting point of the resin or by irradiating light.

The VA amount of VA) is preferably 10 to 40% by weight, and the melt flow index is preferably 15 or less. VA amount is 1
If the VA content is less than 0%, it is unsuitable as a laminated glass material for transparent applications due to its high value, and if the VA content is more than 40%, the effect of the present invention is small. Similarly, the effect of the present invention is small for EVA with a melt flow index of 15 or more.

part is added to the above composition. The amount of plasticizer that can be added is E
It is determined by taking into consideration the compatibility with VA, the required transparency, the impact resistance after being combined with glass, etc., but if it is less than 0.5 parts, there will be little substantial effect, and if it is more than 50 parts, it will affect the composition. Bleeding of the plasticizer or deterioration of physical properties is extremely undesirable.

防止することができる。These plasticizers may be mixed with EVA using a processing machine such as an extruder, roll mill, Banbury, etc.
VA may be immersed in these plasticizers at room temperature or under heating to cause swelling, and a blender, ball mill, etc. may also be used to promote this swelling. Also, the plasticizer is IBVA
It may be added simultaneously with the peroxide or photosensitizer or prior to the addition of the peroxide or photosensitizer. Addition of such a plasticizer is necessary when uniformly mixing peroxide and photosensitizer into KVA, and when forming a film or sheet using various processing machines. By lowering the temperature, it is possible to prevent gelation, scorch, etc. of the composition.

得た。The composition of the present invention in the form of a film or sheet obtained as described above is sandwiched between two glass plates while being heated, and the air bubbles etc. existing between the glass plate and the sheet are expelled and the composition is homogenized. be done. A second advantage of the present invention is that the heating temperature during this sandwiching and leveling can be lowered. As for the method of sandwiching and integrating, the rubber bag method, nip roll method, etc. are adopted as in the case of conventional PVB films. Integrated laminated glass continues to be an EV
It is heated above the melting point of the crystals in A, and is stirred by ultraviolet to visible light or heating, and has excellent 'rh brightness and impact resistance, and is an excellent material that prevents glass from scattering, falling, peeling, etc. when broken. It becomes glass. Which of the above methods is used for crosslinking depends on the formulation of the composition. Needless to say, the transparency of laminated glass is an extremely unique performance, but the present invention has been found to be able to further improve this point, especially when the VA amount is about 20 inches, which was an effect that could not have been predicted in the past. Furthermore, although the addition of plasticizers generally tends to cause deterioration of physical properties, the present invention has also obtained unexpectedly favorable results in that it does not affect the impact resistance of laminated glass.
