Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to ABSm fat
This invention relates to a heat-resistant ABS resin composition with improved moldability, especially styrene copolymerized plum fat.

Various attempts have been made to improve upon the prior art. ABS 8
As a method of imparting heat resistance to the 4-fat resin, methods have been proposed, such as introducing α-methylstyrene as the 4th component into the graft polymer, or blending a material with high heat resistance such as polycarbonate. According to this method, while the heat resistance is the same as above, the moldability tends to decrease.

Like this ZA B Sm fat especially 1 elbow fever A B S #
For example, the issue of moldability is one of the problems in I II, as seen in the magazine [Plastic Edge] August 1956 issue @ 80~
As described on page B3.

It is also possible to increase the heat resistance of the resin by increasing the acrylonitrile component in ABS4M, but even in this case there is a problem with moldability.

Q [As a result, should I add specific additives? This was done based on the discovery that the above objective could be achieved.

Line 4 of the invention, Measure 1 The purpose of the present invention is that heat resistant A B S 4fil resin 141υ1 from the group consisting of 11Ji1 iron and nickel of Groups 1, 2, 2, and A 11 S 4 characterized in that 2 to 10 parts of a complex compound formed by a selected metal and a sigton compound are added.
31 ll1-1 Group 1 Exists.

The ABS resin used in the present invention has heat resistance
BS 1: Refers to the floor, and ABS resin with 11iit heat resistance stamped so that the heat deformation temperature is 85°C or higher is to be used according to ASTM D648-72 standard (load:

In order to give heat resistance to the above IJI<, A
Either a part of styrene, which is one of the main components of B S 4111, is replaced with α-methylstyrene and graft copolymerized, or a copolymer containing α-methylstyrene is used as AB

) or polysulfone after ABS 411 to form e.g. ABS/PC alloy, ABS
Methods such as increasing the acrylonitrile content in the 61 resin can be adopted, but the heat-resistant ABS resins obtained by these methods have problems in moldability. Itll have a remarkable effect on improving 1st hyperplasia.

Next, the complex compound used in the present invention is formed by a specific metal and a sigton compound. Preferred examples of this metal include Na, Li, C

Ca, Zn, Ae of group II, Ti of group II, Sn
and Fe, Ni, etc. Furthermore, zigtone compounds refer to compounds that have two yCo groups in the molecule and can form complex compounds with metals, such as acetylacetone,
aceto1Yii esters, such as ethyl acetoacetate;
Examples include dibensoylmethane.

Next, examples of complex compounds formed by the above metals and diketone compounds used in the present invention include sodium acetylacetonate, calicum acetylacetonate, trichum acetylacetonate, calcicum acetylacetonate, and calcium acetylacetonate. magnesium nate, aluminum triacetylacetonate, titanium tetraacetylacetonate, zinc acetylacetonate, tin bisacetylacetonate dichloride, nickel bisacetylacetonate, sodium ethyl acetylacetonate, potassium ethyl acetoacetate cum, ethyl acetoacetate calcium, ethyl acetoacetate magnesicum, tris ethyl acetoacetate aluminum, tetraethylacetoacetate dicum, bis ethyl acetoacetate dichloride tin,
Ethyl acetoacetate subethyl acetoacetate nickle, dibenzoylmethane magnesium, dibenzoylmethane trisicum, trisdibenzoyl aluminum,
Bisdibenzoylmethane dichloridetin, bisdibenzoylmethanenilaglu, and trisdibenzoylmethaneiron are mentioned.

In the present invention, the moldability of the heat-resistant ABS resin can be improved by adding the above complex compound to the heat-resistant ABS resin. In other words, the complex compound has good compatibility with ABS resin, and by being mixed with ABS resin, at the molding temperature of Aya 1117 (approximately 200 to 240°C),
It has the effect of greatly lowering the melt viscosity of the tJJ resin and facilitates molding at this temperature. On the other hand, at a temperature lower than the L-Ki Ebisugi temperature, for example at room temperature,
Within the range of the amount added according to the present invention, the addition of the above-mentioned complex compound hardly causes any change in the performance and behavior of the ABSr4 fat.

In order to achieve a sufficient formability improvement effect, 2 parts by weight or more are used per 100 parts of ABS wax, and heat-resistant ABS 4aJ resin with impact strength and heat resistance such as heat-changed cedar is used. In order to prevent the expected physical properties from deteriorating contrary to these expectations, for 100 parts by weight of ABS resin,
10-fold is used in a number of cases.

The composition of the present invention is a composition prepared by adding heat-resistant ABST# fat and the above-mentioned complex compound in the above-mentioned quantitative range, and using a kneading roll, a mixer, or other mixing means. Since it has good moldability in terms of fluidity at the molding temperature, it can be easily molded into, for example, irregularly shaped injection molded products with complex structures.

In addition, it is also possible to add combustible materials such as vinyl chloride resin, chlorinated PVC fence resin, and chlorinated polyethylene for the purpose of improving the 9Yffl flammability of the present invention 1111. The amount of flame-retardant oil added is A B S
The amount is preferably 50 parts by weight or less per 100 parts by weight of 4'F4 fat.

When adding chlorine-containing resins such as those mentioned above, organic tin-based stabilizers such as tribasic sulfuric acid, stearic acid (M), calcium stearate, and dioctyltin bis(2-ethylhexylnystyl thiocricolate) mercapto are used. ? lJ /2 It is preferred to use stabilizers which are conventionally known for use with chlorine-containing trees.

Further, when a higher degree of flame retardancy is required, it is also possible to use a flame retardant such as antimony oxide or decabromonaphthalene in addition to the above-mentioned chlorine-containing resin.

In addition to the above, the composition of the present invention may contain chlorine-containing resins or
Flame retardancy can be easily imparted by adding fat and a flame retardant, but blending a chlorine-containing resin with the conventional ABS 4-season fat composition and applying it to one Bosugi will improve heat resistance. It was difficult to put it into practical use due to the large decrease in
Therefore, the fact that it can be easily made flame retardant as described above can be considered as one of the advantages of the present invention.

As mentioned above, the non-invention group 1 material is made of heat-resistant ABS resin 4,
- By adding the ir+- compound described in 1111 of 1, the fluidity is improved as above and the moldability is improved without impairing the desirable characteristics inherent to ABS 4Nia 1 fat. Therefore, the ABS bonding material for F + ground 1, which requires dimensional accuracy, surface smoothness, gloss, and complex shape, etc.
It is suitable for use as a fat.

Furthermore, flame retardancy can be easily imparted by adding a chlorine-containing resin or the like.

Example Hereinafter, the present invention will be explained based on examples.
