Problems solved by technology

[0011] However, although the adhesive composition described in Patent Document 2 or the aqueous emulsion composition described in Patent Document 3 exhibits high adhesive strength to molded articles composed of highly polar copolymers such as ethylene / vinyl acetate copolymers, for example, , it is difficult to achieve sufficient adhesion to low-polarity moldings such as ethylene / α-olefin copolymers described in Patent Document 1

manufacture example

[0214] 100 parts by weight of the ethylene / 1-butene copolymer obtained in Preparation Example (2) above, 0.5 parts by weight of dicumyl peroxide (DCP), and 0.35 parts by weight (TAIC conversion value) of tripropenyl isocyanide Ornithyl ester (TAIC) (trade name: M-60 (TAIC content: 60% by weight) (manufactured by Nippon Chemicals Co., Ltd.)), 7 parts by weight of dicarboxylamine nitride and 10 parts by weight of talc powder The mixture was kneaded on a roll having a roll surface temperature of 100° C. for 10 minutes to form a thin plate.

[0215] Then the thin plate obtained is placed on the stamping die, at 150kg / cm 2 , 160° C., and pressure heating for 12 minutes to obtain a foamed molded product (thickness 24.5 mm, length 1500 mm, width 200 mm).

[0217] Preparation of aqueous dispersant (aqueous emulsion composition)

[0218] With 5 parts by weight of ethylene / α-olefin copolymer (density: 862kg / m 3 , MFR: 1.2g / 10 minutes, trade name: TAFMER-DF610 (man...

Embodiment 2

[0235] In addition to replacing 5 parts by weight of ethylene / α-olefin copolymer (density: 862kg / m 3 , MFR: 1.2g / 10 minutes, trade name: TAFMER-DF610 (manufactured by Mitsui Chemicals)), using 5 parts by weight of ethylene / α-olefin copolymer (density: 885kg / m 3 , MFR: 1.2 g / 10 minutes, brand name: TAFMER-DF810 (manufactured by Mitsui Chemicals, Inc.)), the same operation as in Example 1 was performed to obtain an aqueous emulsion composition.

[0236]Using this aqueous emulsion composition, the cleaned foam molded article and the rubber sheet were adhered in the same manner as in Example 1, and the adhesive strength was measured. The results are shown in Table 1.

Embodiment 3

[0238] In addition to replacing 5 parts by weight of ethylene / α-olefin copolymer (density: 862kg / m 3 , MFR: 1.2g / 10 minutes, trade name: TAFMER-DF610 (manufactured by Mitsui Chemicals)), using 5 parts by weight of ethylene / α-olefin copolymer (density: 870kg / m 3 , MFR: 35g / 10 minutes, trade name: TAFMER-DF7350 (manufactured by Mitsui Chemicals Co., Ltd.), replace 40 parts by weight of turpentine (trade name: gumterebinthN (manufactured by YATUHARA Chemical Co., Ltd.)) and 20 parts by weight of turpentine An aqueous emulsion composition was obtained in the same manner as in Example 1 except for limonene (trade name: D limonene (manufactured by Yatuhara Chemical Co., Ltd.).

[0239] Using this aqueous emulsion composition, the cleaned foam molded article and the rubber sheet were adhered in the same manner as in Example 1, and the adhesive strength was measured. The results are shown in Table 1.

Abstract

Disclosed is an aqueous dispersion containing (A) an ethylene-alpha-olefin copolymer, (B) a modified ethylene-vinyl acetate copolymer, (C) a photopolymerization initiator and (D) an ethylenically unsaturated monomer, and if necessary (E) an ethylene-vinyl acetate copolymer and (F) a nonaqueous organic solvent.

Description

technical field [0001] The present invention relates to an aqueous dispersant, an adhesive composition containing the same, or an adhesive composition such as a primer, and a method for adhering molded articles made of ethylene / α-olefin copolymers using the same. Background technique [0002] In many fields such as building interior and exterior decoration materials, automobile interior decoration materials or glass frames, packaging materials, daily necessities, etc., in order to obtain products with low specific gravity, light weight, softness and high mechanical strength, the technology of bridging foam is used . In order to reduce weight, only foaming the resin will cause a decrease in mechanical strength, but this bridging foam combines molecular chains through the bridging reaction of the resin, suppressing the decrease in mechanical strength, and achieving weight reduction through foaming. [0003] Shoes or clothing, such as the soles of sports shoes (mainly density ...
