Embodiment 1

[0120] 4 kg of crystalline polypropylene having a melt index of 14 g / min (measured according to JIS K7210) and a melting point of 160° C. was charged into a glass-lined reaction vessel, and 50 L of chloroform was added thereto. The inside of the kettle was pressurized to 0.3 MPa in terms of gauge pressure, and it was fully dissolved at a temperature of 110°C. Then, as a radical reaction initiator, 4 g of tert-butylperoxyisopropyl carbonate was added, and chlorine gas was blown in while maintaining the pressure inside the tank at 0.3 MPa to obtain a chlorine content of 30% by weight and a molecular weight of 180,000. Chloroform solution of chlorinated polypropylene. Next, after concentrating the chloroform solution using an evaporator, epoxy compound No. 1 in Table 1 was added as a stabilizer, and chloroform as a reaction solvent was replaced with toluene. Thus, a solution of a chlorinated polyolefin-based resin composition having a solid content concentration of 20% by weight...

Embodiment 2

[0122] Except having used the epoxy compound No. 2 in Table 1 as a stabilizer, the procedure was the same as Example 1, and the solution of the chlorinated polyolefin resin composition was obtained, and the same test was performed. The results are shown in Table 2.

Embodiment 3

[0124] Except having used the epoxy compound No. 3 in Table 1 as a stabilizer, the procedure similar to Example 1 was used to obtain the solution of the chlorinated polyolefin resin composition, and the same test was performed. The results are shown in Table 2.

Abstract

The object of the present invention is to provide a chlorinated polyolefin resin composition, which has excellent adhesion to substrates such as polyolefin resin substrates, forms a good coating film, and has excellent stability. It can be used in coatings, primers, inks, It is useful for applications such as adhesives and heat-sealing agents, and there is no problem in terms of safety. The present invention provides a chlorinated polyolefin-based resin composition containing an α-olefin oxide represented by the general formula (1) and / or an α,ω-olefin oxide represented by the general formula (2), [Chem. 1] [Chem 2] (In the formula, m is an integer of 3 to 26, and n is an integer of 2 to 28).

Description

technical field [0001] The present invention relates to a chlorinated polyolefin resin composition and its use. Background technique [0002] Plastic has many advantages such as high productivity, great freedom of design, light weight, rust resistance, and impact resistance, so it is often used as a material for automobile parts, electrical parts, construction materials, and food packaging films. In particular, polyolefin-based resins are inexpensive materials having various excellent properties such as moldability, chemical resistance, heat resistance, water resistance, and good electrical characteristics. Therefore, polyolefin-based resins are widely used, and they are one of the most anticipated materials for the expansion of their needs in the future. [0003] Polyolefin-based resins are non-polar. Therefore, inks or adhesives containing chlorinated polyolefins, which have strong adhesion to polyolefin resins, are used for coating and bonding of polyolefin resins. How...
