Problems solved by technology

[0006] Emulsified paste (Abang pulp) has been widely used in the pigment/pigment printing of textiles. Since a large amount (75% of the weight of the emulsified paste) of kerosene is used as the internal phase, it not only causes ecological and environmental problems, but also has major problems. Potential safety hazard, has been gradually banned from use
Although currently widely used synthetic thickeners have no environmental and

Abstract

The invention discloses an O/W-type ultralow solid-containing rate kerosene-free printing emulsion paste and a preparation method thereof, the O/W-type ultralow solid-containing rate kerosene-free printing emulsion paste consists of raw materials with the following portions by weight: 70 to 80 portions of methylsiloxane compounds, 20 to 30 portions of water, 2.5 to 4 portions of non-ionic surfactant and 0 to 0.5 portion of anionic surfactant. The preparation method of the O/W-type ultralow solid-containing rate kerosene-free printing emulsion paste comprises the following steps of: placing water which is taken as an external phase in a container under the condition that the temperature T is more 0 DEG C and less than 40 DEG C, slowly adding the non-ionic surfactant and the anionic surfactant which are completely dissolved and evenly stirred; slowly adding the internal phase component, namely, the methylsiloxane compounds, under the condition of high-speed stirring with the rotating speed of 1000 to 10000r/min; controlling the adding speed, ensuring that the added methylsiloxane compounds can be quickly emulsified and dispersed in the water; and stirring for 5 to 10 minutes continuously to obtain the finished products after the paste is formed. The invention has the advantages of no environment and safety problems, good stability and the solid-containing rate approximating zero.

Description

technical field [0001] The invention belongs to the field of pigment / pigment printing emulsification paste for textiles, and in particular relates to an O / W printing emulsification paste with no kerosene and extremely low solid content and a preparation method thereof. Background technique [0002] When printing textiles, the colorant must be adjusted into a high-viscosity color paste to ensure accurate and clear local dyeing effects during the printing process. Therefore, in addition to dye / pigment / paint and other additives in the color paste, the most important thing is the original paste. There are two main types of raw paste for textile printing, one is made of water and solid thickener, including natural hydrophilic polymer raw paste with high solid content and synthetic thickener with low solid content Raw paste; another type is formed by emulsification of two mutually incompatible liquids, that is, emulsified paste with a solid content close to zero. So far, the O / W ...
