Embodiment 1

[0036] Weigh 10kg of strontium stearate, 15kg of zinc stearate, 45kg of magnesium aluminum hydrotalcite, and 5kg of dibenzoylmethane into a high-speed mixer in turn. The mixer runs at a speed of 1200rpm and mixes at 45°C for 15 minutes; then puts 10kg β-(3,5-di-tert-butyl-4-hydroxyphenyl) n-octadecyl propionate, mixed for 10min under the same speed and temperature conditions; finally put 15kg pentaerythritol ester, under the same speed and temperature conditions Mix for 5 minutes, and cool the material to 35°C to obtain the product of the present invention.

Embodiment 2

[0038] Take by weighing 10kg strontium stearate, 15kg zinc stearate, 45kg magnesium aluminum hydrotalcite, 5kg dibenzoylmethane, 5kg three (2-hydroxyethyl) isocyanurate and drop in the high-speed mixer successively, mix The machine runs at a speed of 1200rpm, and mixes at 45°C for 15 minutes; then puts 10kg of n-octadecyl β-(3,5-di-tert-butyl-4-hydroxyphenyl) propionate, and mixes at the same speed and temperature 10 minutes; finally put in 15kg of pentaerythritol ester, mix for 5 minutes under the same rotational speed and temperature conditions, and cool the material to 35°C to obtain the product of the present invention.

Embodiment 3

[0040]Weigh 10kg strontium stearate, 15kg zinc stearate, 45kg magnesium aluminum hydrotalcite, 5kg dibenzoylmethane, 5kg 2,2,4-trimethyl-1,3-pentanediol diisobutyrate Put them into the high-speed mixer one by one, the mixer runs at 1200rpm, mix at 45°C for 15min; , mixed for 10 minutes at the same speed and temperature; finally, 15kg of pentaerythritol ester was added, mixed for 5 minutes at the same speed and temperature, and cooled to 35°C to obtain the product of the present invention.

Abstract

The invention belongs to the technical field of heat stabilizers, and especially relates to a stabilizer for floor films, and a preparation method thereof. The stabilizer for floor films is prepared from, by weight, 3-10 parts of a main stabilizer A, 10-15 parts of a main stabilizer B, 25-55 parts of an auxiliary stabilizer C, 1-5 parts of an auxiliary stabilizer D, 5-10 parts of an antioxidant and 3-15 parts of pentaerythritol ester; the main stabilizer A is at least one of strontium stearate and calcium benzoate; the main stabilizer B is at least one of zinc stearate, lanthanum stearate andzinc benzoate; the auxiliary stabilizer C is at least one of magnesium aluminum hydrotalcite and magnesium aluminum zinc hydrotalcite; and the auxiliary stabilizer D is at least one of dibenzoylmethane, stearoylbenzoylmethane and dodecyl dihydropyridine diformate. Compared with stabilizers in the prior art, the stabilizer prepared in the invention has the advantages of no toxicity, environmental protection, no precipitation, good heat resistance, high transparency, good yellowing resistance and certain ultraviolet aging resistance.

Description

technical field [0001] The invention belongs to the technical field of thermal stabilizers, in particular to a stabilizer for floor film and a preparation method thereof. Background technique [0002] The main components of PVC floor film include PVC resin, plasticizer and heat stabilizer. Heat stabilizer plays an important role in the manufacturing process of plastic products. [0003] There are many kinds of heat stabilizers for PVC plastic processing. The non-environmentally friendly ones include lead and cadmium soap heat stabilizers, and the environmentally friendly ones include calcium zinc-based heat stabilizers, methyl tin stabilizers and heterocyclic stabilizers. Although lead and cadmium soaps have good thermal stability, their inherent high toxicity has greatly limited their application range as the restrictions of environmental protection laws at home and abroad are approaching. In the field of PVC film materials, the use of methyl tin as the main stabilizer is...
