Abstract

The invention relates to red master batches resistant to acids and bases. The red master batches comprise, by weight ratio, 14-18 parts of pigment red 177, 19-22 parts of styrene, 3-4 parts of glycerinum, 4-5 parts of tertiary butyl hydroquinone, 7-9 parts of phenolic resin, 3-5 parts of polyacrylamide and 2-4 parts of limestone flour. The prepared red master batches have good acid-base resistance and stability.

Description

The red master batch of a kind of acid and alkali-resistance
Technical field
The present invention relates to a kind of master batch, particularly relate to the red master batch of a kind of acid and alkali-resistance.
Background technology
Masterbatch has very wide application, can be used in plastics, helps pigment to be dispersed in system uniformly.Masterbatch is generally formed by pigment and mixed with resin, then has good performance after adding some other dispersion agent compositions.In conventional Masterbatch use procedure, because storage period is long, can produce the unsettled situation of Masterbatch character and occur.Simultaneously, because Masterbatch does not have acid-proof alkaline, after it is applied in plastic cement, can the acid-proof alkaline of plastic cement be exerted an influence, so we need to strengthen the acid-proof alkaline of Masterbatch.
Summary of the invention
The technical problem solved: conventional Masterbatch acid-proof alkaline is poor, the problem of less stable.
Technical scheme: the invention discloses the red master batch of a kind of acid and alkali-resistance, red master batch is comprised of according to weight ratio following composition: Pigment red 177 is that 14～18 parts, vinylbenzene are that 19～22 parts, glycerine are that 3～4 parts, tertiarybutylhydroquinone are that 4～5 parts, resol are that 7～9 parts, polyacrylamide are that 3～5 parts, limestone powder are 2～4 parts.Wherein, Pigment red 177 is preferably 14 parts; Vinylbenzene is preferably 22 parts; Glycerine is preferably 3 parts; Resol is preferably 9 parts.
The red agglomerate preparation method of acid and alkali-resistance is as follows: taking Pigment red 177 is that 14～18kg, vinylbenzene are that 19～22kg, glycerine are that 3～4kg, tertiarybutylhydroquinone are that 4～5kg, resol are that 7～9kg, polyacrylamide are that 3～5kg, limestone powder are 2～4kg, with the twin screw cone-type mixer, mixed, mixing time is 15min, re-using twin-screw extruder, to carry out high temperature miscible, temperature is 160 ℃, screw speed is 150r/min, after screw extruding high temperature mixes, mixture is carried out to granulation, drying, obtain red master batch.
Beneficial effect: the red master batch that the present invention prepares has excellent acid-proof alkaline, and magnesium hydroxide solution soaking that can anti-15wt% does not change in 10 days, and the citric acid solution of anti-20wt% soaks and do not change in 10 days.After at room temperature placing 6 months in addition, color and luster does not change.
Embodiment
Embodiment 1
Taking Pigment red 177 is that 19kg, glycerine are that 4kg, tertiarybutylhydroquinone are that 4kg, resol are that 7kg, polyacrylamide are that 5kg, limestone powder are 2kg for 18kg, vinylbenzene, with the twin screw cone-type mixer, mixed, mixing time is 15min, re-using twin-screw extruder, to carry out high temperature miscible, temperature is 160 ℃, and screw speed is 150r/min, after screw extruding high temperature mixes, mixture is carried out to granulation, drying, obtain red master batch.
Embodiment 2
Red agglomerate preparation method is with embodiment 1, and concrete component content is as follows: Pigment red 177 is that 21kg, glycerine are that 3kg, tertiarybutylhydroquinone are that 5kg, resol are that 8kg, polyacrylamide are that 3kg, limestone powder are 3kg for 16kg, vinylbenzene.
Embodiment 3
Red agglomerate preparation method is with embodiment 1, and concrete component content is as follows: Pigment red 177 is that 22kg, glycerine are that 4kg, tertiarybutylhydroquinone are that 4kg, resol are that 9kg, polyacrylamide are that 4kg, limestone powder are 4kg for 14kg, vinylbenzene.
After preparing red master batch, resistance to acids and bases and the stability of red master batch are investigated.The red master batch of embodiment 1, embodiment 2, embodiment 3 is put into respectively the magnesium hydroxide solution soaking 10 days of 15wt%, and the citric acid solution of 20wt% soaks 10 days.At room temperature place 6 months in addition.
The red master batch of embodiment 1, embodiment 2, embodiment 3 was the magnesium hydroxide solution soaking of 15wt% 10 days, and the citric acid solution of 20wt% soaked after 10 days, did not all change, and had good resistance to acids and bases.After at room temperature placing 6 months in addition, color and luster does not change, and has satisfactory stability yet.
