Detailed Description

In order to facilitate the understanding of the technical solutions of the present invention for those skilled in the art, the technical solutions of the present invention will now be further described with reference to specific embodiments.

According to the preparation process of the pigment printing adhesive without the acrylonitrile hard monomer, on the premise of not changing other components and proportion of the original formula of the pigment printing adhesive, styrene and partial soft monomer isooctyl acrylate are used for replacing all hard monomer acrylonitrile in the original formula of the pigment printing adhesive, the consumption of a main raw material butyl acrylate is reduced in the original formula, and acrylonitrile is not used at all. The preparation cost of the pigment printing adhesive is saved on the premise of not changing the whole process flow. Meanwhile, the prepared adhesive does not reduce the amount and the quality.

The preparation process of the pigment printing adhesive comprises the following steps:

the first step is as follows: adding all monomer components of the adhesive into an emulsifying tank, fully stirring, dispersing and emulsifying, wherein the emulsifying time is 15-25 minutes, and the stirring speed is 2500-3000 r/min, so as to obtain an emulsion;

the second step is that: and (3) putting the emulsion tank into a plastic bottle, and putting a radiation source for irradiation for 6-8 hours to obtain the adhesive. The plastic bottle is a transparent plastic bottle with the capacity of 1000ml, and the radiation source is r rays.

According to the technical scheme, in the preparation process of the coating printing adhesive without acrylonitrile hard monomers, the adhesive mainly comprises the following monomer components:

in the following, 7 examples are proposed for the above technical solution, and the specific formulation of each example is shown in table 1 below.

Table 1:

pigment printing binders without acrylonitrile hard monomers were prepared according to the formulation of examples 1 to 7, respectively, and then the pigment printing binders prepared according to the formulation of examples 1 to 7 were used to treat printed cloth samples, respectively, and the product properties thereof are shown in table 2 below.

Table 2:

as can be seen from the above table 2, the printed cloth sample treated by the coating printing adhesive without the acrylonitrile hard monomer in the technical scheme is environment-friendly, nontoxic, good in color fastness, wear-resistant, solvent-resistant, good in weather resistance, bright in color and non-combustible.

In the technical scheme, after the styrene and the isooctyl acrylate are utilized and are irradiated by a radiation source, the effect which is at least the same as that of adding acrylonitrile is obtained, meanwhile, the dosage of the main component butyl acrylate in the raw materials can be properly reduced, and the prepared adhesive dosage cannot be reduced. The preparation cost of the pigment printing adhesive is saved on the premise of not changing the whole process flow. Meanwhile, the prepared adhesive does not reduce the amount and the quality.

Based on the technical scheme, through investigation, the cost of styrene is 50% -60% of that of acrylonitrile, and the cost of isooctyl acrylate is equivalent to that of butyl acrylate. Therefore, the styrene and the isooctyl acrylate are used for replacing acrylonitrile and partial butyl acrylate, and the preparation cost is effectively reduced.
