Embodiment 1-5

[0076] An environment-friendly sun-resistant printing overprint white paste, comprising the following components:

[0077] Water-based acrylic emulsion, titanium dioxide, triazine compounds, fillers, water;

[0078] Triazine compounds are 2,5-dihydro-6-hydroxy-2-methyl-5-oxo-3-mercapto-1,2,4-triazine, 2-amino-4-methoxy-6- A compound of one or more of methyl-1,3,5-triazine, 2,4,6-tris(2-pyridyl)triazine, and phenyl-1,3,5-triazine.

[0079] The filler is a compound of white carbon black and silicate.

[0080] The silicate includes one or more of zirconium silicate, calcium silicate, aluminum silicate, cesium silicate and barium silicate.

[0081] The input amount (unit Kg) of each component among the embodiment 1-5 sees table 2 for details

[0082] Table 2

[0083]

[0084] refer to figure 1 , is the preparation method of a kind of environment-friendly sun-resistant printing overprint white pulp of embodiment 1-5, comprises the following steps:

[0085] Step 1), stir an...

Embodiment 6

[0090] Compared with embodiment 5, the difference only lies in:

[0091] In step 1), after each component is added, stir for 20 minutes to obtain a mixed solution;

[0092] In step 2), after each component is added, the disperser is used to continuously stir at a speed of 1500r / min for 40min, and after grinding, filter with a 270-mesh gauze.

Embodiment 7

[0094] Compared with embodiment 5, the difference only lies in:

[0095] In step 1), after each component is added, stir for 30 minutes to obtain a mixed solution;

[0096] In step 2), after each component is added, the disperser is used to continuously stir at a speed of 1500r / min for 50min, and after grinding, filter with a 300-mesh gauze.

Abstract

The invention relates to the field of coatings, in particular to an environment-friendly type light-resisting printing cover printing white paste and a preparing method thereof. The environment-friendly type light-resisting printing cover printing white paste particularly comprises 30 parts of water-based acrylic emulsion, 10 to 20 parts of titanium dioxide, 2 to 4 parts of triazine compounds, 16to 20 parts of filler and 8 to 12 parts of water. The invention further discloses a preparing method of the environment-friendly type sunshine-resisting printing cover printing white paste. The methodspecifically comprises the following steps of firstly, stirring and filtering, wherein the water and the water-based acrylic emulsion are added into a container, and are continuously stirred, the triazine compounds are added, after adding, stirring is carried out for 10 to 30 min, and mixed liquid is obtained; and secondly, dispersion grinding, wherein the titanium dioxide and the filler, stirring is carried out for 30 to 50 min, grinding is carried out, and a filter part of 200 to 300 meshes is used for filtering. The white paste has the effects that a pattern formed through printing and dyeing is higher in light fastness, not prone to fading, not prone to color changing and not prone to yellowing.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an environment-friendly sun-resistant printing overprint white paste and a preparation method thereof. Background technique [0002] At present, with the development of society and the progress of human civilization, people have higher and higher requirements for clothes, especially the appearance of clothes. Patterns will be printed. [0003] When the existing clothes are printed and dyed, printing overprinting white paste is often used, and white patterns can be printed and dyed through printing overprinting white paste, which is very aesthetically pleasing. [0004] There are following defects in the above-mentioned prior art scheme: [0005] However, when people wear clothes and walk outdoors, the clothes will be exposed to sunlight, and the white pulp is mainly made of polymer materials. The printed and dyed white patterns change color and turn yellow, seriously affectin...
