Example Embodiment

[0036]Example

[0037]A new slow-release type is used as an environmental stabilizer for U-PVC large-caliber water supply accessories, using raw materials containing the following weight percentages:

[0038]Zinc stearate 25%;

[0039]Calcium stearate 6%;

[0040]Sec 5%;

[0041]Uracil 5%;

[0042]Zeolite 28%;

[0043]Calcium hydroxide 5%;

[0044]Antioxidant 4%;

[0045]Synergistic heat stabilizer 5%;

[0046]Polyol 5%;

[0047]Lanthanum maleamic acid 4%.

[0048]Prepared by the following steps:

[0049]Step 1. Add zinc stearate, calcium stearate, Sec, 1,3-dimethyl-6-aminouracil, polyol and lanthanum maleamic acid in proportion to the reaction kettle at 35°C. Stir evenly for 18min in the middle;

[0050]Step 2: Add zeolite and calcium hydroxide and mix and stir for 20 minutes;

[0051]Step 3. Finally, add the synergistic stabilizer, antioxidant, light stabilizer and ultraviolet absorber, stir for 9 minutes under the condition of 75°C and nitrogen protection, and obtain the PVC stabilizer after cooling;

[0052]Step 4. For the PV...

Abstract

The invention discloses a novel slow-release environment-friendly stabilizer applied to a U-PVC large-caliber water supply accessory. The stabilizer comprises the following components in percentage byweight: 28% of zinc stearate, 8% of calcium stearate, 5% of Sika, 5% of uracil, 30% of zeolite, 5% of calcium hydroxide, 4% of an antioxidant, 10% of a synergistic heat stabilizer and 5% of polyol. The invention relates to the technical field of production of U-PVC large-caliber water supply accessories. The novel slow-release environment-friendly stabilizer applied to the U-PVC large-caliber water supply accessory solves the problem that a stabilizer which is high in stability, proper in cost, capable of improving the stability of a product and specially used for production of the U-PVC large-caliber water supply accessory does not exist in the prior art.

Description

technical field [0001] The invention relates to the technical field of production of U-PVC large-caliber water supply fittings, in particular to a new slow-release environmentally friendly stabilizer applied to U-PVC large-caliber water supply fittings. Background technique [0002] As a general-purpose plastic material, rigid polyvinyl chloride (PVC-U) has the characteristics of flame retardant, chemical corrosion resistance, wear resistance, good insulation and high mechanical strength. Therefore, PVC-U is widely used in chemical industry, building materials, light industry , home appliances, packaging and other fields. In recent years, with the continuous advancement of urbanization in our country, plastic materials have developed rapidly in the domestic building material pipeline industry, and have gradually replaced traditional metal pipes, and the caliber of products used is also increasing. [0003] In the production process of PVC raw materials for PVC-U large-diame...
