Problems solved by technology

However, it is difficult to satisfy the required functions with one material
For example, an unstretched polyolefin film used for sealing by heat sealing is excellent in hot workability, but has insufficient oxygen barrier properties.
On the contrary, nylon film has excellent gas barrier properties, but poor heat sealability

Embodiment

[0179] Hereinafter, the present invention will be described in more detail with reference to specific synthesis examples and examples, but the present invention is not limited to these examples. In addition, in the following examples, unless otherwise specified, "part" and "%" mean "part by mass" and "% by mass", respectively.

[0180]

Synthetic example 1

[0181] (Synthesis Example 1) Synthesis of Polyester Polyol (A1-1)

[0182] Using 410 parts of terephthalic acid, 66 parts of isophthalic acid, 173 parts of adipic acid, 238 parts of cyclohexanedimethanol, 116 parts of 1,4-butanediol, and 142 parts of 1,6-hexanediol, according to Conventional methods to synthesize polyester polyols. The obtained polyester polyol (A1-1) has crystallinity, a number average molecular weight (Mn) of 10000, a glass transition temperature (Tg) of 2°C, a melting point of 115°C, and a heat of fusion (ΔH) of 9.9J / g, the hydroxyl value is 11 mgKOH / g, and the acid value is 1.7 mgKOH / g.

Synthetic example 2

[0183] (Synthesis Example 2) Synthesis of Polyester Polyol (A1-2)

[0184] Using 411 parts of terephthalic acid, 66 parts of isophthalic acid, 177 parts of adipic acid, 248 parts of cyclohexanedimethanol, 116 parts of 1,4-butanediol, and 129 parts of 1,6-hexanediol, according to Polyester polyols were synthesized by conventional methods. The obtained polyester polyol (A1-2) has crystallinity, a number average molecular weight (Mn) of 22000, a glass transition temperature (Tg) of 4°C, a melting point of 141°C, and a heat of fusion (ΔH) of 0.49J / g, the hydroxyl value is 4mgKOH / g, and the acid value is 2.3mgKOH / g.

Abstract

Provided are: a two-component-type adhesive having excellent moldability, heat resistance, and resistance to moist heat; and a laminate, a molded body; and a packaging material which are obtained by using the two-component-type adhesive. A two-component-type adhesive is characterized by comprising: a polyol composition (A) containing a crystalline polyester polyol (A1); and a polyisocyanate composition (B) containing an isocyanate compound (B), wherein the crystalline polyester polyol (A1) has a glass transition temperature of -20 DEG C to 10 DEG C, a melting point of 80 DEG C to 160 DEG C, and a number average molecular weight of 2,000 to 30,000.

Description

technical field [0001] The present invention relates to a two-component adhesive, a laminate obtained by using the two-component adhesive, a molded body, and a packaging material. Background technique [0002] For packaging materials used in the packaging of various storage items represented by food, daily necessities, and electronic components, strength and resistance to breakage are required in order to protect the contents from shocks received during distribution, etc., and from deterioration due to oxygen and moisture. , Gas barrier and other functions. When heat sterilization is performed on the contents, retort resistance, heat resistance, etc. are required, and transparency may also be required so that the contents can be confirmed. However, it is difficult to satisfy required functions with one material. For example, an unstretched polyolefin film used for sealing by heat sealing is excellent in hot workability, but has insufficient oxygen barrier properties. In c...
