DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a polyethylene resin composition for powder coatings, and more specifically to a polyethylene resin composition excellent as a powder coating, which is made by blending modified polyethylene and two types of linear low-density polyethylene in a certain ratio. relating to things. Powder coatings containing modified polyethylene as one component have been known for some time (Japanese Patent Application Laid-open No. 155242/1983).
However, even if a polyethylene resin composition simply blended with modified polyethylene and polyethylene is used as a powder coating to coat metal plates, etc., the adhesion to the metal may be insufficient, or the surface of the coating after coating may be insufficient. There are various problems such as the occurrence of so-called bumps or pinholes, which prevent a sufficient rust-preventing effect. The present inventors solved the above-mentioned problems of conventional powder coatings, and developed a resin suitable for powder coatings that has excellent adhesion to objects to be coated such as metal plates and has a good painted appearance. We conducted extensive research to develop the composition. As a result, by blending modified polyethylene with linear low-density polyethylene, which has a relatively small melt index, and further blending it with another type of linear low-density polyethylene, which has a relatively large melt index, the desired polyethylene resin can be produced. It was discovered that a composition can be obtained, and the present invention was completed. That is, the present invention has a melt index of 0.5 to
8g/10min Linear low density polyethylene (a) 85 to 35% by weight and linear low density polyethylene or high density polyethylene modified with unsaturated carboxylic acid or its derivative (b) 15 to 65% by weight are blended. A polyethylene resin composition for powder coatings prepared by blending 1 to 50 parts by weight of a resin composition (A) and 99 to 50 parts by weight of a linear low-density polyethylene (B) with a melt index of 10 to 30 g/10 minutes. It provides: As described above, the resin composition (A), which is one component of the powder coating polyethylene resin composition of the present invention, is composed of both components (a) and (b). Here, component (a) is linear low density polyethylene, which is so-called
It is called LLDPE, and contains ethylene and about 0.2 to 20 mol% of other α-olefins (propylene, butene-1,4-methylpentene-1, hexene-
1, octene-1, etc.) under conditions similar to those used in the production of conventional high-density polyethylene (HDPE). The density of this LLPE is generally 0.910 to 0.940g/
cm3 . In addition, the melt index (MI)
A range of 0.5 to 8 g/10 min, preferably 3 to 8 g/10 min should be selected. If this MI is less than 0.5, kneading properties with other components will be poor, leading to poor dispersion. As a result, the physical properties of the resulting polyethylene resin composition, particularly its adhesive properties, become poor, and the appearance of the surface of the coating film becomes poor when it is painted. Conversely, if MI exceeds 8, the resulting polyethylene resin composition will have poor dispersibility and poor coating surface condition. On the other hand, component (b) to be blended with component (a) is linear low density polyethylene (modified LLDPE) or high density polyethylene (modified HDPE) modified with an unsaturated carboxylic acid or its derivative.
The LLDPE to be modified here is a copolymer of ethylene and about 0.2 to 2.0 moles of other α-olefins, and has a density of 0.900 to 0.940 g/cm 3 , similar to LLDPE which is component (a). , MI is preferably 0.1 to 30 g/10 minutes. In addition, the HDPE to be modified has a density of 0.945 to 0.970 g/cm 3 and an MI of 0.01 to 35 g/cm 3 .
You can use it as appropriate from a range of 10 minutes. Various methods can be considered for modifying these LLDPEs and HDPEs with unsaturated carboxylic acids or derivatives thereof, and any of them may be used. For example, the process proceeds by adding a radical initiator to LLDPE or HDPE and maleic anhydride in the presence or absence of a solvent and heating the mixture. During the modification reaction, other vinyl monomers such as styrene or rubbers such as liquid rubber and thermoplastic rubber may also be present. In addition,
Examples of unsaturated carboxylic acids that can be used here include acrylic acid, methacrylic acid, maleic acid, fumaric acid, itaconic acid, crotonic acid, citraconic acid, sorbic acid, mesaconic acid, and angelic acid. Derivatives include acid anhydrides, esters, amides, imides, metal salts, etc., such as maleic anhydride, itaconic anhydride, citraconic anhydride, methyl acrylate, methyl methacrylate, ethyl acrylate, and butyl acrylate. , maleic acid monoethyl ester, acrylamide, maleic acid monoamide, maleimide, N-
Examples include butylmaleimide, sodium acrylate, and sodium methacrylate. Modified LLDPE or modified LLDPE obtained in this way
HDPE contains unsaturated carboxylic acids or their derivatives
It is contained in a proportion of 0.01 to 15% by weight, preferably 0.5 to 4% by weight. If the content of the unsaturated carboxylic acid or its derivative is too small, the adhesion will be poor; if it is too large, the degree of crosslinking will increase and kneading will become difficult. In addition, LLDPE after the above modification treatment and
MT of HDPE, i.e. modified LLDPE or modified HDPE is
0.001 to 20 g/10 minutes, preferably 0.2 to 1.0 g/10 minutes. The resin composition (A) contains LLDPE, which is the above-mentioned component (a).
It is prepared by blending the component (b) with modified LLDPE or modified HDPE. The blending ratio at this time is (a) component
85-35% by weight, preferably 85-50% by weight, component (b)
It should be between 15 and 65% by weight, preferably between 20 and 50%. If the blending ratio of component (b) exceeds 65% by weight, kneading properties will be poor, and when painted, the appearance of the painted surface will be poor. On the other hand, if it is less than 15% by weight, the adhesion is poor and it is not suitable as a paint. Next, the component (B) to be blended with the above resin composition (A) is linear low density polyethylene (LLDPE),
Basically, like the previous component (a), ethylene and 0.2~
It is a copolymer with 20 mol% of other α-olefins and has a density of 0.910 to 0.940 g/mm 3 . However, M.I.
It is larger than the LLDPE of component (a), and usually has an MI of 10 to 30 g/10 minutes, preferably
10-25g/10 minutes. If the MI is less than 10, the paintability of the resulting polyethylene resin composition will be reduced, and the coating film will lack smoothness, resulting in unevenness on the surface. Conversely, if the MI exceeds 30, the coating surface becomes easily damaged. The polyethylene resin composition for powder coatings of the present invention can be obtained by blending the above-mentioned components (A) and (B). In this case, the blending ratio of component (A) and component (B) is 1 to 50 parts by weight, preferably 3 to 30 parts by weight of component (A), and 99 to 50 parts by weight, preferably 97 to 70 parts by weight of component (B). It should be parts by weight. If the blending ratio of component (A) is less than 1 part by weight, the resulting polyethylene resin composition will have poor adhesion, while if it exceeds 50 parts by weight, the MI of the resulting polyethylene resin composition will decrease, resulting in uneven coating, etc. Undesirable. In addition to the above-mentioned components (A) and (B), desired fillers such as pigments can be added to the polyethylene resin composition for powder coatings of the present invention. The blending of components (a) and (b) in obtaining the component (A) of the present invention, and the blending of components (A) and (B) in the production of the polyethylene resin composition for powder coatings of the present invention. The formulation can be done in various ways, but
Preferably, solvent kneading is carried out using a single-screw or twin-screw kneader, an intermixer, a Banbury mixer, a co-kneader, or the like. The polyethylene resin composition of the present invention thus obtained is particularly suitable as a powder coating, has good adhesion to metals, and can be coated with an excellent appearance. Therefore, the polyethylene resin composition of the present invention is
It is effectively used as a powder coating, especially as a metal rust-preventing and non-polluting coating. Next, the present invention will be explained in more detail with reference to Examples. Reference example 1 (Production of modified high-density polyethylene (modified HDPE)) High-density polyethylene (HDPE) (density 0.945g/
cm3 , MI26g/10min) 100 parts by weight, maeic anhydride

Maleic anhydride-modified low-density polyethylene (modified LDPE) was obtained by carrying out the same operation as in Reference Example 1 except that MI23 g/10 minutes) was used. the resulting denaturation
The maleic anhydride content of LDPE is 2.3wt%,
MI was 0.1 g/10 minutes. Examples 1 to 10 and Comparative Examples 1 to 6 Predetermined amounts of polyethylene and modified polyethylene shown in Table 1 were solvent-kneaded in a twin-screw kneader at 200°C to obtain a masterbatch (resin composition (A)). . The obtained masterbatch and a predetermined amount of LLDPE as component (B) were melt-kneaded in a twin-screw kneader to obtain a polyethylene resin composition. This resin composition was pulverized at 70°C using a rotary pulverizer to obtain a powder coating. Next, a metal steel plate (JIS STRY) with a thickness of 2.5 mm is
