Abstract
The invention relates to a moisture-proof calcium-zinc composite heat stabilizer and a preparation method thereof. A moisture-proof calcium-zinc composite heat stabilizer comprises three layers of structures from inside to outside, namely an adsorption carrier layer, a calcium-zinc composite heat stabilizer layer and a hydrophobic material layer, and the preparation method comprises the following steps: high-temperature adsorption, namely fully stirring the adsorption carrier and the calcium-zinc heat stabilizer at a low speed, heating until the calcium-zinc composite heat stabilizer is molten, and stirring at a low speed: 50-100 rpm, time: 30-120min, temperature: 100-120 ℃; and (3) coating at low temperature, cooling until the calcium-zinc composite heat stabilizer is solidified, continuously adding a hydrophobic material, and stirring at high speed for coating, wherein the stirring speed at high speed is as follows: 500-1000prm, time: 5-30min, temperature: 30-50 ℃. The invention does not need reworking and baking, does not have high requirement on packaging, improves the production efficiency, reduces the cost, absorbs the heat stabilizer by the carrier containing the large cavity, and can effectively prevent the heat stabilizer from absorbing external moisture by sealing the outer end by adopting the hydrophobic material.
Description
Technical field
The invention belongs to chemical technology fields, more particularly to a kind of moisture-proof Ca-Zn composite heat stabilizer and its preparation side
Method.
Background technology
Polyvinyl-chloride use Ca-Zn composite heat stabilizer is generally acknowledged in the world nontoxic, environment-benign heat stabilizer, and has valence
The advantages that lattice are cheap, lubricity is good has extremely wide development space, becomes most active in composite thermal stabilizer in recent years
Field.However, current Ca-Zn composite heat stabilizer with respect to conventional composite lead salt stabilizer, has a defect in performance --- it is easy
The moisture absorption.It is in particular in：The Ca-Zn composite heat stabilizer resting period is long afterwards（Such as one month）, it is easy to absorb moisture in air, weight
Amount increases；The PVC pellets or cable of Ca-Zn composite heat stabilizer are added, is easy to absorb outside moisture, material surface is caused to produce
Angry hole, resistance decline.Especially in the southern plum rain season in China, moisture absorption phenomenon more very, causes seriously to PVC product factory
Loss, currently on the market independent brand calcium zinc heat stabilizer be directed to this problem, there are no suitable solutions, only according to
It the measures such as takes drying to do over again, be vacuum-packed by PVC product producer to reduce the negative effect that the moisture absorption is brought, cause PVC systems
The problems such as product producer low production efficiency, high investment.
