Embodiment 1

[0019] Example 1 : The composition by weight of the color paste for water-based polyurethane foaming in the present invention is as follows: 38% of pigment; 6% of fatty alcohol polyoxyethylene ether; 6% of SOLSPERSE series super-dispersing auxiliary; 50% of water.

[0020] The above pigments can be selected as black pigment C.I.PB7, PRINTEXG carbon black, specific surface area 40-50m 2 / g, white pigment C.I.PW6, titanium dioxide, specific surface area 11-18m 2 / g, red pigment C.I.PR48:2, specific surface area 45-55m 2 / g, yellow pigment C.I.PY74, specific surface area 40-50m 2 / g, or blue pigment C.I.PB15:1, specific surface area 60-70m 2 / g; in this example, the pigment used is carbon black PRINTEXG.

[0021] The preparation method of embodiment 1 is: add 6 grams of fatty alcohol polyoxyethylene ether and 6 grams of SOLSPERSE hyperdispersant in 50 grams of water, stir for 15 minutes with a rotating speed of 800 rev / min, slowly add 38 grams of carbon black PRINTEXG, and us...

Embodiment 2

[0022] Example 2 : The composition by weight of the color paste for water-based polyurethane foaming in the present invention is: C.I.PR48:2 red pigment 36%; fatty alcohol polyoxyethylene ether 6%; SOLSPERSE series hyperdispersing aid 8%; water 50%.

[0023] The preparation method of Example 2 is as follows: add 6 grams of fatty alcohol polyoxyethylene ether and 8 grams of SOLSPERSE hyperdispersant to 50 grams of water, stir for 15 minutes with a rotating speed of 800 rpm, and slowly add 36 grams of C.I.PR48:2 red pigment. , disperse at a high speed of 2000 rpm for 30 minutes, and grind it into a horizontal sand mill until the fineness is less than 15um.

[0024] For the above-mentioned embodiment 1 and embodiment 2, the physical and chemical indicators that its product has after testing are shown in the following table:

Abstract

The invention discloses a water-based polyurethane foaming color paste, which is characterized in that: the composition in parts by weight is: 35-45% of pigment; 5-10% of fatty alcohol polyoxyethylene ether; 3-8% of SOLSPERSE series hyperdispersive aid %; water 40-60%, the pigments are black pigment C.I.PB7, white pigment C.I.PW6, red pigment C.I.PR48:2, yellow pigment C.I.PY74 and blue pigment C.I.? One or more of PB15:1. The beneficial effects of the invention are: low viscosity facilitates automatic material supply, which greatly reduces the cost of product color change and improves production efficiency; it belongs to a resin-free color paste with water as a carrier, and is especially suitable for water-based For foamed polyurethane products, the added amount of the product is within 3% of the multicomponent components used by customers, which is easy to use and has good environmental protection performance.

Description

technical field [0001] The invention relates to a polyurethane color paste, in particular to a water-based polyurethane foam color paste. Background technique [0002] Polyurethane foam is a new type of material. Due to its light weight, breathability and adjustable characteristics, it has a wide range of applications. It is widely used in civil aviation, transportation, automobiles, clothing, toys, furniture, beds, transportation, refrigeration, construction, heat insulation It is widely used in industries such as plastics and has become one of the most widely used varieties in plastics. [0003] At present, polyurethane foam is mainly colored with toner or color paste. Direct use of toner dyeing, due to the high specific surface area of ​​organic pigments, it is difficult to disperse directly in polyether polyols, so it is difficult to add enough toner to produce defects such as insufficient color and rough surface of the product; due to pigment dispersion The flocculati...
