Abstract
The present invention relates to technical field of coatings, especially a kind of composite type heat stabilizer, is made of forming for following parts by weight: 100-150 parts of rare earth thermal stabilizer, 60-100 parts of zinc calcium composite thermal stabilizer, 20-100 parts of auxiliary heat stabilizer, 90-500 parts of lubricant, 2-6 parts of polyalcohol and 5-30 parts of phosphite ester.A kind of composite type heat stabilizer of the invention, it is mixed and is made by the heating of rare earth thermal stabilizer, zinc calcium composite thermal stabilizer, auxiliary heat stabilizer, lubricant, polyalcohol and phosphite ester, the synergistic effect of each component is given full play to, the initial stage of the rare earth complex heat stabilizer and long-term thermal stability performance are all good, cost is relatively low, asepsis environment-protecting is a kind of environment-friendly high-efficiency heat stabilizer kind, can be applied to PVC processing.
Description
Technical field
The present invention relates to auxiliary agent technical field, especially a kind of composite type heat stabilizer.
Background technique
Polyvinyl chloride is one of five big synthetic resin general in the world, and dosage is maximum, extensive with superior performance
For every field such as construction industry, agricultural, daily necessities.Processing heat stability is poor when due to PVC high temperature, in its processing and forming
Heat stabilizer be must be added to maintain its performance, common heat stabilizer mainly has lead salts, organic tin, terres rares and metal
The stabilizers such as soaps.Lead salt type thermal stabilizing agent is cheap, thermostable effect is good, and dosage is bigger, but its toxicity is big, serious to endanger
Evil human health simultaneously pollutes environment.Metal soap thermal stabilizers effect limited capacity.And organic tin heat stabilizer performance efficiency,
Contamination hazard is small, but expensive, at high cost.Rare earth thermal stabilizer, exclusive use effect is less desirable, and performance needs to be mentioned
Height, but compounded with other heat stabilizers and can be realized efficient effect.Therefore it develops a kind of with efficient, nontoxic, at low cost
Heat stabilizer has very important meaning.
Summary of the invention
In order to overcome the existing unconspicuous deficiency of insulating moulding coating heat insulation, the present invention provides a kind of composite type heat is steady
Determine agent, is added by rare earth thermal stabilizer, zinc calcium composite thermal stabilizer, auxiliary heat stabilizer, lubricant, polyalcohol and phosphite ester
Hot mixing stirring is made.
The technical solution adopted by the present invention to solve the technical problems is: a kind of composite type heat stabilizer, by following weight
The composition of part is made: 100-150 parts of rare earth thermal stabilizer, 60-100 parts of zinc calcium composite thermal stabilizer, auxiliary heat stabilizer 20-
100 parts, 90-500 parts of lubricant, 2-6 parts of polyalcohol and 5-30 parts of phosphite ester.
Further, effect is best when including rare earth thermal stabilizer parts by weight are 100 parts.
Further, effect is best when including zinc calcium composite thermal stabilizer parts by weight are 60 parts.
Further, effect is best when including auxiliary heat stabilizer parts by weight are 20 parts.
The invention has the advantages that a kind of composite type heat stabilizer of the invention, multiple by rare earth thermal stabilizer, zinc calcium
It closes heat stabilizer, auxiliary heat stabilizer, lubricant, polyalcohol and phosphite ester heating to be mixed and be made, give full play to each
The synergistic effect of component, the initial stage of the rare earth complex heat stabilizer and long-term thermal stability performance are all good, and cost is relatively low, no poison ring
It protects, is a kind of environment-friendly high-efficiency heat stabilizer kind, can be applied to PVC processing.
Specific embodiment
A kind of composite type heat stabilizer, is made of forming for following parts by weight: 100-150 parts of rare earth thermal stabilizer, zinc calcium
60-100 parts of composite thermal stabilizer, 20-100 parts of auxiliary heat stabilizer, 90-500 parts of lubricant, 2-6 parts of polyalcohol and phosphorous acid
5-30 parts of ester.
Column 1 are embodied: by 100 parts of rare earth thermal stabilizer, 60 parts of zinc calcium composite thermal stabilizer, auxiliary heat stabilizer 20
Part, 90 parts of lubricant, 2 parts of polyalcohol and 5 parts of phosphite ester of stirring solvent are mixed and made into auxiliary agent, have given full play to each component
Synergistic effect, the initial stage of the rare earth complex heat stabilizer and long-term thermal stability performance are all good, and cost is relatively low, asepsis environment-protecting, are one
Kind environment-friendly high-efficiency heat stabilizer kind can be applied to PVC processing.
Column 2 are embodied: by 150 parts of rare earth thermal stabilizer, 100 parts of zinc calcium composite thermal stabilizer, auxiliary heat stabilizer 100
Part, 500 parts of lubricant, 6 parts of polyalcohol and 30 parts of phosphite ester of stirring solvent are mixed and made into auxiliary agent, have given full play to each component
Synergistic effect, the initial stage of the rare earth complex heat stabilizer and long-term thermal stability performance are all good, and cost is relatively low, and asepsis environment-protecting is
A kind of environment-friendly high-efficiency heat stabilizer kind can be applied to PVC processing.
Described above to be merely exemplary for the purpose of the present invention, and not restrictive, those of ordinary skill in the art understand,
In the case where not departing from spirit and scope as defined in the appended claims, many modifications, variation or equivalent can be made, but all
It will fall within the scope of protection of the present invention.
