Abstract

The invention discloses iron oxide red for leather, which is prepared from the following raw materials in parts by weight: 90-100 parts of iron oxide red, 2-4 parts of acrylate resin, 1-2 parts of methyl methacrylate, 10-20 parts of ethyl acetate, 0.1-0.3 part of zinc oxide, 0.1-0.3 part of zinc stearate, 0.2-0.4 part of zinc acetate and 0.2-0.4 part of alkyl glycoside.

Description

A kind of leather red iron oxide

Technical field

The present invention relates to red iron oxide field, is exactly a kind of leather red iron oxide.

Background technology

Red iron oxide (Iron Oxide Red) claims again that iron oxygen is red, colcother, rust are red, has natural and artificial two kinds.Natural title is western red, is substantially pure ferric oxide, be redness powder.Due to the difference of production method and operational condition, their crystalline structure and physical behavior have very large difference, and color and luster changes in orange light to blue light extremely purple lightbetween. opacifying powerall very large with tinting strength. density5-5.25.There are superior fast light, resistance to elevated temperatures, and resistance to atmospheric influence, resistant foul smell body, resistance to all bases.The in the situation that of only heating in concentrated acid, just can dissolve gradually.

Summary of the invention

The object of the present invention is to provide a kind of leather red iron oxide

Above-mentioned purpose realizes by following scheme:

A kind of leather red iron oxide, it is characterized in that: it is that raw material by following weight parts makes: red iron oxide 90-100, acrylate resin 2-4, methyl methacrylate 1-2, ethyl acetate 10-20, zinc oxide 0.1-0.3, Zinic stearas 0.1-0.3, zinc acetate 0.2-0.4, alkyl glycoside 0.2-0.4.

Described a kind of leather red iron oxide, is characterized in that:.

Preparation method is:

(1) acrylate resin, methyl methacrylate, ethyl acetate are mixed by weight, obtain coating resin standby;

(2) zinc oxide, Zinic stearas, zinc acetate, alkyl glycoside and appropriate amount of deionized water are mixed, at 30-40 ℃, after stirring reaction 5-12 minute, add red iron oxide, at 40-50 ℃, stir 10-12 minute, take out and dry, abrasive dust, obtains modified powder;

(3) modified powder and coating resin are mixed by weight, under 100-200 rev/min, stir 10-20 minute, take out, naturally dry in the shade, abrasive dust, obtains.

Beneficial effect of the present invention is: the present invention is made an addition in leather, and itself and all the other raw material consistencies are good, and acid and alkali-resistance, does not fade.Acrylate resin, methyl methacrylate form compact film, acid and alkali-resistance outward in red iron oxide.

Embodiment

A leather red iron oxide, it is that raw material by following weight parts (kg) makes: red iron oxide 100, acrylate resin 4, methyl methacrylate 2, ethyl acetate 20, zinc oxide 0.3, Zinic stearas 0.3, zinc acetate 0.4, alkyl glycoside 0.2.

Described a kind of leather red iron oxide,

Preparation method is:

(1) acrylate resin, methyl methacrylate, ethyl acetate are mixed by weight, obtain coating resin standby;

(2) zinc oxide, Zinic stearas, zinc acetate, alkyl glycoside and appropriate amount of deionized water are mixed, at 40 ℃, stirring reaction, after 12 minutes, adds red iron oxide, stirs 12 minutes at-50 ℃, takes out and dries, and abrasive dust, obtains modified powder;

(3) modified powder and coating resin are mixed by weight, stir 20 minutes under 200 revs/min, take out, naturally dry in the shade, abrasive dust, obtains.

The present embodiment product performance analytical data is as following table:

Project	Index	Detected result
			105 ℃ of volatile matters (%)	≤1.0	0.94
Tinctorial strength (%)	95-105	97.1
			Resistance to 200 ℃/30min(△ E)	≤1.0	0.78
