Description

The present invention relates to an additive for resins excellent in antistatic properties, antifogging properties, filler dispersibility improvement and stability during processing, a masterbatch or a resin composition containing the same, a molded article , and a method for improving resin properties. .

  Many commonly used plastics have low polarity, and are easily charged or dewed easily under normal room temperature and humidity conditions. If the plastic is charged, it may be an obstacle to the production process, dirt may be attached to the product, and printing defects may occur. In addition, when a food packaging material such as a wrap film has dew condensation, there is a problem that the film surface cannot be clouded due to dew condensation. In the film for agriculture, when dew condensation occurs, there is a problem that the transmittance of sunlight is lowered and the growth of the crop is deteriorated, or water drops fall on the crop to cause pest damage. In addition, fillers such as calcium carbonate, talc, and glass fiber are generally filled for the purpose of improving the rigidity, impact resistance, and heat resistance of the resin (plastic). These fillers are compatible with plastics. In many cases, the solubility is poor and a satisfactory effect cannot be obtained without being sufficiently dispersed in the resin, or unevenness may occur due to poor dispersion of the filler during processing, resulting in failure.

  In order to solve these problems, resin additives such as antistatic agents, antifogging agents, and dispersing agents are generally included in the resin to make the resin surface hydrophilic or to make the interface between the resin and filler compatible. Is called. As such a resin additive, a low molecular surfactant is commonly used.

Surfactants used as additives for resins are classified into anionic, cationic, nonionic, and amphoteric types when classified according to ionicity. Among these, the anionic system does not have a significant surface hydrophilizing effect. Cationic and amphoteric ones have a large surface hydrophilizing effect but have low heat resistance and are susceptible to problems such as coloring. Nonionic type also has a surface hydrophilization effect that is not so great, but due to the molecular structure, it is easy to adjust the hydrophilic / hydrophobic balance by adjusting the number of moles of hydrophilic groups added and the chain length of hydrophobic groups. Since it is easy to apply, and problems such as coloring are less likely to occur, it is used alone as an additive for resins, or in combination with an anionic or cationic system.
For the purpose of improving the heat resistance of the polyester resin, a method using a polyoxyethylene alkyl ether or a polyglycerol fatty acid ester (for example, see Patent Document 1), and a method using a polyglycerol fatty acid ester as an antistatic agent for a polyester resin (for example, Patent Document 2) is disclosed, but it is not sufficient in terms of sustainability of the effect.

As nonionic surfactants, ethylene oxide adducts of alkylamines and ethylene oxide adducts of alkylamides are used as highly effective substances, but they contain nitrogen atoms in the molecule and cause yellowing of the resin. Cheap. Also, ethylene oxide adducts such as higher alcohols, glycerin fatty acid esters, and sorbitan fatty acid esters can be used as additives for resins, but depending on the resin, sufficient effects may not be seen or the sustainability of the effects may be poor. is there. In addition, stearic acid monoglyceride is commonly used as a nonionic surfactant, but stearic acid monoglyceride is decomposed when used in combination with anionic, cationic, or nitrogen-containing nonionic surfactants, resulting in inconvenience.

The present invention will be described in more detail. Hereinafter, the “compound represented by the formula (1)” may be referred to as the compound of the present invention.
The compound of the present invention contained in the resin additive according to the present invention is represented by the formula (1).
RO- (A) n-H (1)
In the formula (1), R represents an alkyl group having 8 to 22 carbon atoms. The alkyl group may be linear or branched, and may be a saturated alkyl group or an unsaturated alkyl group. Examples of the alkyl group that can be used in the present invention include n-octyl, n-nonyl, n-decyl, n-undecyl, n-dodecyl, n-tridecyl, n-tetradecyl, n-pentadecyl, n-hexadecyl, and n-heptadecyl.

  In the formula (1), n is an average degree of polymerization, and although it depends on the production method of the compound represented by the formula (1), n is generally not monodispersed but a value having a distribution. n can be calculated by the following formula (2) based on the hydroxyl value.

  In formula (2), MWal represents the average molecular weight of the alkyl alcohol.

In formula (1), the number of carbon atoms of the alkyl group and the value of n are determined by the target resin of the compound of the present invention and the required performance. The compound of the present invention needs to have hydrophilicity and hydrophobicity according to the polarity of the target resin species. However, the hydrophobicity increases as the carbon number of the alkyl group increases, and the hydrophilicity increases as the carbon number decreases.
And when the value of n increases, hydrophilicity increases, and when the value of n decreases, hydrophobicity increases. Further, the molecular weight determined by the sum of the carbon number of the alkyl group and the value of n is also important. When the molecular weight is small, the initial surface hydrophilicity is improved, but the sustainability with time is deteriorated. In addition, there is a demerit that the compound of the present invention easily volatilizes. When the molecular weight is large, the initial surface hydrophilicity is deteriorated, but the sustainability is improved, and the influence of a decrease in physical properties of the resin is reduced. The carbon number of the alkyl group and the value of n must be selected in a balanced manner from these tendencies, but the alkyl group preferably has a carbon number in the range of 8 to 22, and includes an octyl group, a lauryl group, a myristyl group, and stearyl. Groups are preferred. The alkyl group may have a single carbon number or a mixture of a plurality of carbon atoms.
The value of n is from 2 to 20 at the number-average, good Mashiku is 4-10.

For example, an alkyl alcohol and 3 to 5 equivalents of glycidol with respect to the alkyl alcohol are reacted at 50 to 100 ° C. under an alkali catalyst, and unreacted alkyl alcohol and free polyglycerol are reacted at 130 to 200 ° C. under reduced pressure.
