Acrylate or methacrylate having 8 alkyl groups [hereinafter collectively referred to as (meth)acrylate] 100
Polyfunctional acrylic compound o, oos ~ 5 parts by weight
A method is employed in which a composition containing 0.1 to 5 parts by weight of a photopolymerization initiator is applied to a substrate, and the composition is polymerized by irradiation with ultraviolet rays. [Detailed description of means] Examples of the (meth)acrylate having an alkyl group having 4 to 18 carbon atoms include butyl (meth)acrylate, isobutyl (meth)acrylate, and 2-ethylhexyl (meth)acrylate.
Acrylate, nonyl (meth)acrylate, hexadecanol (meth)acrylate, stearyl (meth)acrylate
(Meth)acrylates having straight or branched alkyl groups, such as acrylates, can be used. Polyfunctional acrylic compounds are radically polymerizable (meth)
It refers to a compound having a plurality of 7-acryloyl groups, and for example, the following compounds can be used. ■ Tetramethylene glycol diacrylate CH2=C
HCOO(CH2)40CO--CH=CH2 (For example, manufactured by Osaka Organic Chemical Industry Co., Ltd., trade name Viscoat #195) ■Hexamethylene glycol diacrylate CH2=C
HCOO(CH2)a 0CO--CH=CH2 (For example, same Viscoat #230) ■2.2-Bis(acryloylmethyl)propane (CH2=CHCOO
CH2)2 C(CH3)2 (for example, same Viscoat #215) ■ Trioxypropylene glycol diacrylate CH2=CHCOO(CH2CH20) 3 --C
OCH=CH2 (for example, Viscoat #310) ■ Tetraoxypropylene diacrylate CH2=CHCOO (CH2
CH(CH3)O)4--COCH=CH2 (For example, same Viscoat #335) ■(Triacryloylmethyl)ethylmethane (CH2=C1-1cOO
cH2)3 C(C2Hs ) (for example, Viscoat #295) (triacryloylmethyl)hydroxymethylmethane (CH2=CHCOOCH2)3 CCH20H (for example, Viscoat #300) (CH2=CHCO
OCH2CH20) 3PO (for example, Viscoat 3PA) ■CH2=CHCOOCH2CH(OH)CH2-(O
H) CH2) nOcOcH=cH2 (e.g., Visco-#540, average molecular weight about 480) (e.g., Visco-Droa 00) ■CH2=CH
COO(CH2)50 - molecular weight approximately 700) The blending ratio of this polyfunctional acrylic compound is 0°005 to 1001i (for 1 part of the (meth)acrylate 1001i)
The range is 5 parts by weight. If it is less than 0.005 parts by weight, the flexibility of the surface of the blocking member becomes too large and the blocking performance for imaging, sound, heat, etc. decreases, and if it exceeds 5 parts by weight, the blocking member becomes too hard and cannot exhibit its blocking performance. It disappears. As a photopolymerization initiator, benzoin isopropyl ether, p-N, isoamyl N-dimethylaminobenzoate,
7.7,8.8-tetracyanoquinodimethane, 2.2-
Dimethoxy-2-phenylacetophenone, 2-hydroxycyclohexylphenyl ketone, benzophenone,
2-methyl[4-(methylthio)phenyl]-2-morpholino-1-propanone and the like can be used. The blending ratio of the photopolymerization initiator is in the range of 0.1 to 5 parts by weight based on 100 parts by weight of the (meth)acrylate. If it is less than 0.1 part by weight, the (meth)acrylate and polyfunctional acrylic compound will not cure, and if it exceeds 5 parts by weight, the photopolymerization initiator will become an impurity, reducing performance such as the adhesiveness of the blocking member. Costs will also rise. As the base material to which the composition containing the (meth)acrylate, a polyfunctional acrylic compound, and a photopolymerization initiator is applied, resin, rubber, metal, coated metal, etc. can be used. The blocking member of the present invention is obtained by applying a composition prepared by blending the (meth)acrylate with a predetermined amount of a polyfunctional acrylic compound and a photopolymerization initiator to a thickness of about 0.1 to 3 mm on the base material,
It can be easily obtained by irradiating ultraviolet light from a predetermined distance for several minutes. If the coating thickness of the above composition is less than 0.1 m+, it will be difficult to sufficiently exhibit vibration, sound, heat shielding performance, etc. If it exceeds 3 m+I+, it will be difficult to apply the composition, and it will take a long time to cure with ultraviolet rays. Become. [Function] By employing the above means, the composition consisting of (meth)acrylate, polyfunctional acrylic compound, and photopolymerization initiator applied to the base material is rapidly cured by ultraviolet rays, and the composition has improved flexibility and adhesiveness. Carbon number 4-18 that exhibits
The high molecular weight acrylic polymer obtained by copolymerizing (meth)acrylate with a polyfunctional acrylic compound that forms an appropriate cross-linked structure exhibits sufficient adhesive strength, and this It is believed that the high molecular weight acrylic polymer effectively exhibits insulation properties such as vibration damping, sound proofing, and heat insulating properties. [Examples 1 to 15 and Comparative Examples 1 to 7] Next, Examples embodying the present invention will be described in comparison with Comparative Examples. In addition, in each of the following, parts represent parts by weight. (1) Preparation of composition to be applied Mix the (meth)acrylate, polyfunctional acrylic compound, and photopolymerization initiator shown in Tables 1 and 2 below to prepare a composition to be applied to the surface of the substrate. did. (2) Preparation of test piece After applying the above composition to a thickness of 0.1 inch on a polypropylene resin plate, covering the surface with a polyethylene terephthalate release tape, irradiation with ultraviolet rays from a height of 20 cm for 8 minutes. After the composition was polymerized, the release tape was removed. After drying at 100°C for 2 minutes, the composition was applied to a polypropylene resin plate, which was prepared in the same manner, and was stacked with an adhesion area of 251IIm x 25IIII, followed by pressure bonding under a load of 5kg for 1 minute and tested. It was a piece. (3) Measurement of squeak noise One polypropylene resin plate of the above test piece was moved against the other polypropylene resin plate at an amplitude of 101 m at an amplitude of 60 m/min.
The squeaking noise was measured by making the test move back and forth as shown below. The results are shown in Tables 3 and 4. ○: No squeak was generated. △: Creaking noise occurred. ×: A loud squeak occurred. (4) Measurement of tensile shear strength
The tensile shear strength was measured under the condition of lin. Tables 3 and 4 show the tensile shear strengths measured for the test pieces of each example and comparative example. Table-2 The abbreviations in Table-1 and Table-2 have the following meanings. n-BA: n-butyl acrylate 2-El (A

Table 4 As can be seen from Tables 3 and 4 above, in Examples 1 to 15 of the present invention, the tensile shear strength at room temperature was 1.0 to 1.
．． The blocking members were destroyed at 3 kg/-, and the adhesive strength between the polypropylene resin plates was excellent.
In either case, no squeak was generated. On the other hand, when the blending ratio of the polyfunctional acrylic compound was outside the range of the present invention (Comparative Example 1)
．． 2. 4. 5) When the blending ratio of the photopolymerization initiator is outside the range of the present invention (Comparative Examples 3 and 6.7), the tensile shear strength is o, i - o. The weight is as low as 9kg/cm, and squeaks are often heard. The reason why the shielding members of each example exhibit such excellent performance is that the (meth)acrylate having 4 to 18 carbon atoms exhibits flexibility and adhesiveness, and the polyfunctional acrylic compound that forms an appropriate crosslinked structure. is copolymerized by ultraviolet irradiation, and the resulting high molecular weight acrylic polymer exhibits sufficient adhesive strength. It is thought that it effectively exhibits insulation properties such as vibration-proofing, sound-proofing, and heat-insulating properties. Therefore, when manufacturing products such as resins and rubbers, the specific composition can be applied to areas that require blocking performance, irradiated with ultraviolet rays, and then bonded to a mating member to exhibit blocking performance as is. . [Effects of the Invention] The blocking member of the present invention has sufficient adhesive strength, and
By irradiating it with ultraviolet rays, it has the effect of immediately exhibiting blocking functions such as vibration proofing, sound proofing, and heat insulation.
