专利说明:
Stable PVC stabilized with N, N-dimethyl-6-aminouracil The present invention relates to stabilizing hard or semi-rigid PVC with heavy metals by using certain N, N-dimethyl-6-aminouracils defined by the formula (1) below. DE 1 694 873 describes the use of certain uracil compounds to stabilize PVC from heat and oxidative stresses. However, this document describes only a soft PVC composition comprising aminourasil. Other aminoauracyl and aminothiouracil compounds are also described as PVC stabilizers. (EP 0 065 934, EP 0 354 179, EP 0 041 479). It is currently known that these aminouracil and aminothiouracil compounds have a limited fitness for soft PVC since they cause contamination or decolorization in systems where their presence is stabilized. Surprisingly, however, PVC containing less than 20% plasticizer, so-called hard, semi-rigid PVC, can be highly stabilized using the compound of formula (1) described below. Pollution is no longer a problem. It is an object of the present invention to stabilize a hard or semi-rigid PVC by using a specific N, N-dimethyl-6-aminouracil. Therefore, A) rigid or semi-rigid PVC with up to 20% plasticizer, and B) at least one compound of the formula (1) It is to be noted that the perchlorate compound, the glycidyl compound, the beta-diketone, the beta-ketoester, the dihydropyridine, the polydihydropyridine, the polyol, the disaccharide alcohol, the sterically hindered amine (tetraalkylpiperidine compound) (Zeolite), hydrotalcite, alkali alumocarbonate (doosonite) are not present in the composition: Wherein X is O or S, and R is H or a phenyl group. B) is a compound of formula (1) wherein X is O, in particular B) Is preferred. The present invention relates to the use of a compound of formula (1) for stabilizing hard or semi-rigid PVC under the above-mentioned cues. The compound of formula (1) is advantageously incorporated into hard or semi-rigid PVC to be stabilized in an amount advantageously from 0.01 to 10% by weight, preferably from 0.05 to 5% by weight, in particular from 0.1 to 3% by weight, based on the total composition . The compositions of the present invention may also contain other additives such as stabilizers, adjuvants and processing aids, typical alkali metal compounds, alkaline earth metal compounds, lubricants, plasticizers, pigments, fillers, phosphates, thiophosphates, thiophosphates, mercaptocarboxylates, , Antioxidants, UV absorbers, light stabilizers, fluorescent brighteners, impact modifiers, gelling agents, antistatic agents, biological poisons, metal deactivators, flame retardants, foaming agents as well as defoamers.

The compounds of formula (1) are prepared by known methods as described in more detail in the following examples. Parts and percentages are by weight unless otherwise indicated. Example 1: Preparation of 6-amino- 1, 3-dimethyluracil. 224.8 g of N, N , -dimethylurea, 238.7 g of cyanoacetic acid and 310.9 g of acetic anhydride were heated to 80 DEG C with stirring under nitrogen. The mixture was stirred at 80 DEG C for 2 hours and evacuated to 50 mbar to distill off the acetic acid. After cooling, 35 g of cooling water of 250 g was added to this mixture. The mixture was stirred for 10 minutes and then 567 g of 15% sodium hydroxide solution was added dropwise while cooling with ice. The pH does not rise above 7 to 475 ml. When the pH exceeds 7, the precipitation changes, and when the mixture is heated from 23 ° C to about 50 ° C, the pH is 10.2. After 200 g of water was added, the mixture was stirred for 10 minutes and heated under reflux. After refluxing for 1 hour, the mixture was cooled to 20 < 0 > C and suction filtered. The filtered cake was washed with 2 x 100 g of cooling water and then dried in a vacuum dryer at 90 < 0 > C. Yield: 334 g (86.1% of theory), m.p .: 282 캜. Example 2: Preparation of 6-phenylamino-1,3-dimethyluracil. A mixture of 39.1 g of aniline and 24.5 g of 1,3-dimethylbarbituric chloride was placed in a 100 ml three-necked flask and refluxed with stirring at 190 DEG C for 15 minutes. The mixture was cooled to room temperature and then 300 ml of water was added. Upon stirring, a pale blue precipitate forms, which is collected by suction, washed with ether and dried to constant weight. Recrystallization from methylene chloride / activated carbon gave the product as a colorless product which was dried. Yield: 22.5 g (69.5% of theory), m.p. 190 ° C. Example 3: Electrostatic test. The dry mixture consisting of the components recited in the following production variables was rolled for 5 minutes at 180 DEG C on a mixer roller. A 0.3 mm test piece was taken from the rolled sheet thus obtained. The film samples were subjected to a thermal stress test in an oven at 180 ° C. Yellowness Index (YI) was measured at 5 to 10 minute intervals according to ASTM D-1925-70. The results are shown in the following table. A low yellowness index value means good stability.
