Abstract
The present invention relates to technical field of coatings, especially a kind of heat stabilizer, is made of forming for following parts by weight: 5-8 parts of polymer metal compound soap, 2-3 parts of stearate, 2-3 parts of benzoate, 0.3-0.8 parts of dihydropyridine, 0.3-0.6 parts of beta-diketon, 8-10 parts of mineral oil, 4-6 parts of polyalcohol, 0.3-0.8 parts of antioxidant and 10-30 parts of phosphite ester.A kind of heat stabilizer of the invention, it is mixed and is made by the heating of polymer metal compound soap, stearate, benzoate, dihydropyridine, beta-diketon, mineral oil, polyalcohol, antioxidant and phosphite ester, it is environmentally friendly, nontoxic, it is at low cost, solve the problems, such as that the single heat stabilizer heat-stable time of tradition is short, poor fluidity.
Description
Technical field
The present invention relates to auxiliary agent technical field, especially a kind of 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 heat stabilizer,
Pass through polymer metal compound soap, stearate, benzoate, dihydropyridine, beta-diketon, mineral oil, polyalcohol, antioxidant
It is mixed and is made with phosphite ester heating.
The technical solution adopted by the present invention to solve the technical problems is: a kind of heat stabilizer, by the group of following parts by weight
At being made: 5-8 parts of polymer metal compound soap, 2-3 parts of stearate, 2-3 parts of benzoate, 0.3-0.8 parts of dihydropyridine, β-
0.3-0.6 parts of diketone, 8-10 parts of mineral oil, 4-6 parts of polyalcohol, 0.3-0.8 parts of antioxidant and 10-30 parts of phosphite ester.
Further, effect is best when including polymer metal compound soap parts by weight are 5 parts.
Further, effect is best when including stearate parts by weight are 2 parts.
Further, effect is best when including benzoate parts by weight are 2 parts.
The invention has the advantages that a kind of heat stabilizer of the invention, passes through polymer metal compound soap, stearic acid
Salt, benzoate, dihydropyridine, beta-diketon, mineral oil, polyalcohol, antioxidant and phosphite ester heating are mixed and are made,
It is environmentally friendly, nontoxic, it is at low cost, solve the problems, such as that the single heat stabilizer heat-stable time of tradition is short, poor fluidity.
Specific embodiment
A kind of heat stabilizer is made of forming for following parts by weight: 5-8 parts of polymer metal compound soap, stearate 2-3
Part, 2-3 parts of benzoate, 0.3-0.8 parts of dihydropyridine, 0.3-0.6 parts of beta-diketon, 8-10 parts of mineral oil, 4-6 parts of polyalcohol,
0.3-0.8 parts and phosphite ester 10-30 parts of antioxidant.
Column 1 are embodied: by 8 parts of polymer metal compound soap, 3 parts of stearate, 3 parts of benzoate, dihydropyridine 0.8
Part, 0.6 part of beta-diketon, 10 parts of mineral oil, 6 parts of polyalcohol, 0.8 part of antioxidant and the mixing of 30 parts of phosphite ester of stirring solvent
Auxiliary agent is made, solves the problems, such as that the single heat stabilizer heat-stable time of tradition is short, poor fluidity.
Column 2 are embodied: by 5 parts of polymer metal compound soap, 2 parts of stearate, 2 parts of benzoate, dihydropyridine 0.3
Part, 0.3 part of beta-diketon, 8 parts of mineral oil, 4 parts of polyalcohol, 0.3 part of antioxidant and the mixing of 10 parts of phosphite ester of stirring solvent
Auxiliary agent is made, solves the problems, such as that the single heat stabilizer heat-stable time of tradition is short, poor fluidity.
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.
