Embodiment 1

[0053]First raise the temperature of the reactor to 60°C, put in 500g of stearic acid, continue to heat up to 140°C, and then put in 160g of yellow dandelion at a speed of 1kg / min after the stearic acid is completely melted (every throwing 25g, stay for 5-10min, so that the yellow dandelion can Completely react with stearic acid to generate the product lead stearate); after cooling down to 125°C and stirring for 8 minutes, add 8g of ash calcium, further react for 10min, and then add 4g of acetic acid (to consume the unreacted yellow lead to generate the product lead acetate); then add 50g polyethylene wax, 210g tribasic lead sulfate, 350g heavy calcium carbonate, 80g barium stearate, 10g dibasic lead stearate, 10g bisphenol-A and 10g paraffin; Keep stirring at ℃, and after the material is evenly stirred, release the material to obtain the product; it can also be further granulated (or tableted) to obtain a granular (or flake) product.

Embodiment 2-3

[0055] The specific preparation method is the same as in Example 1, and its specific formulation is as shown in Table 1.

Abstract

The invention belongs to the field of a plastic stabilizer, and specifically relates to a compound stabilizer for a plastic bubble tube and a preparation method thereof. The compound stabilizer for the plastic bubble tube comprises the following raw materials in parts by weight: 495-510 parts of stearic acid, 158-165 parts of yellow lead, 6-10 parts of calcium hydroxide, 4-5 parts of acetic acid,45-55 parts of polyethylene wax, 208-215 parts of tribasic lead sulfate, 345-360 parts of heavy calcium carbonate, 75-95 parts of barium stearate, 20-30 parts of dibasic lead stearate, 10-15 parts ofbisphenol-A and 10-20 parts of paraffin. The obtained compound stabilizer is suitable for the plastic bubble tube, excellent in stability, excellent in lubrication effect, low in cost, and low in lead content.

Description

technical field [0001] The invention belongs to the field of plastic stabilizers. Specifically, the invention relates to a composite stabilizer for plastic bubble tubes and a preparation method thereof. Background technique [0002] As we all know, stabilizers are mainly used in the processing of plastic products, mainly to stabilize the plastic, to ensure that the plastic can not be decomposed at a higher temperature, can be processed smoothly, and made into the desired product. Stabilizers can be divided into five categories according to their chemical structures: base lead salt stabilizers, metal soaps, organotin compounds, organic stabilizers and composite stabilizers. [0003] There are many patents on composite stabilizers for plastics, such as "Preparation method of PVC composite heat stabilizer ZWS (patent application No. 200310109677.0)" etc. Although these patented products have the advantage of being non-toxic, they have the disadvantages of high price and compli...
