Embodiment 1

[0007] Standard pigment release agent (PE-2 type release agent)

[0008] In the experimental reactor, first inject 2.5g of triethanolamine, 58g of water and 1g of sodium lauryl sulfate into the prepared emulsion, add 1g of sodium bisulfite and 0.5g of potassium persulfate under stirring conditions, and heat up to 50°C as the initiator; add 400g of butyl acrylate, 40g of acrylic acid and 100g of styrene monomer mixture dropwise into the initiator emulsion, and after the polymerization is initiated, the system automatically heats up to 70°C-85°C. Temperature, after continuing to react for 1h-2h, it becomes a copolymer of acrylic acid and styrene. In this copolymer emulsion, add 3 g / kg of Turkish red oil and 3 g / kg of fumed silicon dioxide (using a high specific surface area ratio) with a percentage set by the formula, and then add 250 g of starch with a degree of etherification of about 0.7-1.2 ( Hydroxyl has been shielded) and appropriate amount of water, after stirring the ab...

[0011] Formula by mass percentage:

[0012] Acrylic and styrene copolymer is 70%,

[0013] Silica 0.3%,

[0014] Turkish red oil is 0.2%,

[0015] The starch with a degree of etherification of about 1.2 is 18%,

[0016] Tributyl ester is 0.4%,

[0017] Adjust to 100% with water.

[0018] In an industrial reaction kettle, first inject 2.5kg of triethanolamine, 58kg of water and 1kg of sodium lauryl sulfate into the prepared emulsion, add 1kg of sodium bisulfite and 0.5kg of potassium persulfate under stirring conditions, and heat up to 50 ℃ as the initiator; add 500kg of butyl acrylate, 50kg of acrylic acid and 150kg of styrene monomer mixture dropwise into the initiator emulsion. After continuing to react for 1.5h, it becomes a copolymer of acrylic acid and styrene. In this copolymer emulsion, 2kg (0.2%) of Turkish red oil and 3kg (0.3%) of fumed silicon dioxide (with a high specific surface a...

Embodiment 3

[0020] Pigment release agent for cold transfer printing paper of wool (protein fiber) type fabric

[0021] Formula by weight percentage:

[0022] Acrylic and styrene copolymer is 50%,

Abstract

The invention relates to a pigment separator of cold-transfer print paper, whose formula in mass percentage comprises: the copolymer of crylic acid and styrene in 35-80%; silicon dioxide in 0.05-0.5%; Turkey chilli oil in 0.2-1.8%; three-butonate in 0.1-0.8%; starch in 5-30% whose etherified degree is 0.7-1.2; and water. The producing method comprises: in the emulsion of initiator, mixing and adding sodium bisulfite and potassium peroxodisulfate, and heating it to 50Deg. C; adding the butyl acrylate, the mixture of crylic acid and styrene monomer into said emulsion, to initiate aggregation, and heating it to 70-80Deg. C; at said temperature, reacting for 1-2h, to attain the copolymer; adding turkey chilli, silicon dioxide, three-butonate, and starch whose etherified degrees is 0.7-1.2 and adding water; attaining the cold transfer print paper. The inventive transfer print paper coated with separator has the function for shielding carrier, with better print transfer property, anti-penetrate property, and anti-compress property, etc, to support the coil paper production.

Description

technical field [0001] The invention relates to the printing and dyeing industry in the textile industry, in particular to the formulation and synthesis of a pigment release agent for cold transfer printing paper. Background technique [0002] Transfer printing paper has become a new method for daily industrial decoration and textile printing. It is to use the printing method to print the pattern or text to be printed on the special paper with suitable dye ink, and print it into a kind of transfer printing paper, and then make the dyed side of the transfer printing paper close to the printed fabric. Combined, the dye ink is released and peeled off from the paper by pressure, and the pattern or text on the transfer printing paper is transferred to the fabric. At present, transfer printing methods can be divided into two categories: dry transfer printing, namely thermal transfer printing and pressure-sensitive transfer printing; and wet transfer printing, namely cold transfer...
