Abstract

The invention relates to a PVC (polyvinyl chloride) heat stabilizer and a preparation method thereof, and particularly relates to a heat stabilizer for wallpaper and a preparation method of the heat stabilizer. The potassium-zinc liquid stabilizer for the PVC wallpaper is prepared from the following components in proportion by weight: 59.3%-60.3% of 2-ethylhexanoic acid, 5.6%-6.0% of diethylene glycol monobutyl ether, 7%-7.5% of potassium hydroxide, 13.9%-14.5% of zinc oxide, and 13.2%-14% of butyl cellosolve. The potassium-zinc liquid stabilizer can be used for solving the problem of abnormal odour of products and the problem of environment pollution due to solvent volatilization in the manufacture process; the dosage of the potassium-zinc liquid stabilizer is reduced by 100% compared with that of the conventional stabilizer; the colour of the wallpaper is beautiful; and the potassium-zinc liquid stabilizer has the characteristics of being high in foaming capacity, uniform in cell, excellent in whiteness and the like. Compared with international products with same functions, the potassium-zinc liquid stabilizer has the advantages of very great price superiority and higher competitiveness.

Description

The PVC wallpaper is with potassium zinc liquid stabilizer and preparation method thereof
Technical field
The present invention relates to a kind of pvc thermo-stabilizer and preparation method thereof, relate in particular to a kind of thermo-stabilizer that is applied to wallpaper and preparation method thereof.
Background technology
Thermo-stabilizer is one type can be prevented or reduce polymkeric substance and in the course of processing, be heated and degraded or crosslinked, the additive in elongate composite material work-ing life take place.Stablizer commonly used according to the staple classification can be divided into salt base class, fatty acid soaps class, organo-tin compound, composite type heat stablizer and pure organic cpds class.
1) alkali type thermal stabilizing agent: the alkali type thermal stabilizing agent is meant and is combined with the inorganic of " alkali " and organic acid lead salt; This type stablizer has good thermotolerance, weathering resistance and point insulating property, and cost is low, and the transparency is poor; Certain toxicity is arranged, and consumption is generally 0.5% ~ 5.0%.
2) fatty acid thermo-stabilizer: this type thermal stabilizing agent is meant the compound of being made up of fatty acid radical and metals ion, also claims metal soap thermal stabilizers, and its performance is relevant with the kind of acid group and metals ion, and general consumption is 0.1% ~ 3.0%.
3) organic tin thermo-stabilizer: this type thermal stabilizing agent can form ligand with unstable chlorine atom in the SE molecule, and in ligand the carboxylic acid group and the unsettled chlorine atomic substitutions of organotin.The characteristics of this type thermal stabilizing agent are that stability is high, and the transparency is good, excellent heat resistance, and weak point is that price is more expensive.
4) composite type heat stablizer: this type thermal stabilizing agent is the mixture that the liquid or solid mixture that is the basis with salt base class or metallic soap class and organotin are the basis, and wherein metallic salt has calcium-magnesium-zinc, barium-calcium-zinc, barium-zinc and potassium-zinc etc.; Organic acid such as organic lipid acid, naphthenic acid, oleic acid, phenylformic acid and Whitfield's ointment etc. commonly used.
5) organic cpds thermo-stabilizer: the main stabilizer that this type thermal stabilizing agent can use separately except that minority (mainly being nitrogenous organic cpds); Also comprise high boiling polyvalent alcohol and phosphorous acid ester; Phosphorous acid ester normal and metal(lic)stabilizer and usefulness; Can improve weathering resistance, the transparency of matrix material, improve the surface color of goods.
The mechanism of action of PVC thermo-stabilizer is following: in 1) absorbing and HCL, suppress its autocatalytic action.This type stablizer comprises lead salts, organic acid metal soap class, organo-tin compound, epoxy compounds, phenates and metal mercaptide salt etc.They can react with HCL, suppress the reaction that PVC takes off HCL.2) unsettled chlorallylene atom suppresses to take off PVC in the displacement PVC molecule.Combine with the unstable chlorine atom generation coordination of PVC molecule like organotin stabilizer, in ligand, organotin and unstable chlorine atomic substitutions.3) with polyene structure generation addition reaction, destroy the formation of big conjugated system, reduce painted.The salt of unsaturated acid or ester contain two keys, with conjugated double bond generation diene addition reaction in the PVC molecule, thereby destroy its conjugated structure, suppress variable color.
The existing domestic stablizer that is used for wallpaper is often big at manufacturer's fabricate-leather process energy input; Improved production cost; Traditional potassium zinc stabilizer solvent is generally all greater than 50%, and solvent just will volatilize when temperature reaches 130 ℃, and in manufacturing processed temperature of oven up to 220 ℃; Its solvent certainly will volatilize in a large number, and air is polluted.
Summary of the invention
The defective that exists for the stablizer that solves above-mentioned wallpaper; An object of the present invention is to provide a kind of PVC wallpaper and use the potassium zinc liquid stabilizer; It is at high temperature non-volatile that this stablizer does not have any solvent; Having solved product has the problem of peculiar smell, have the characteristics of safety and environmental protection, and this stablizer reduces 100% as the stabilizing agent specially used of wallpaper than traditional stablizer on consumption.Another object of the present invention provides the preparation method of above-mentioned PVC wallpaper with the potassium zinc liquid stabilizer.
In order to realize first above-mentioned purpose, the technical scheme below the present invention has adopted:
The PVC wallpaper is used the potassium zinc liquid stabilizer, and this stablizer is prepared from the component of following weight ratio:
