preparation Embodiment 1

[0027] The preparation method of the spray-free metallic aluminum pigment with embrittlement performance comprises the steps of:

[0028] 1. Adopt the raw material ratio of Example 1 in the formula table of the above-mentioned spray-free metal aluminum pigment, that is, weigh the consumption of raw materials:

[0029] Metallic aluminum pigment (5um) 60%, modified ABS resin 30%, diffusing powder 6%, mica 3% and NaF 1%.

[0030] 2. Add metallic aluminum pigment, embrittlement agent and diffusing powder into the kneader in sequence, and pre-mix for 30 minutes to obtain a mixture.

[0031] 3. Then add modified ABS resin, then add petroleum solvent. The petroleum solvent is a kind of environmentally friendly mineral oil, such as Mobil hydrocarbon cleaning agent D40, D60, D80, etc. The petroleum solvent in it acts as a dilution and wetting function and is volatile Drop, do not participate in the physical and chemical reaction.

[0032] Due to the high-intensity shearing force of t...

preparation Embodiment 2

[0041] Adopt the raw material proportioning of the embodiment 2 in the above-mentioned spray-free metal aluminum pigment formula table, promptly weigh the consumption of raw material:

[0042] Metallic aluminum pigment (15um) 68%, modified ABS resin 27%, diffusing powder 2%, mica 1% and Al 2 o 3 2%.

[0043] The steps for the preparation of the following spray-free metal aluminum pigments are the same as the steps of Preparation Example 1.

[0044] Such as figure 2 Shown is a schematic diagram of the detection and comparison of metallic aluminum pigments for spray-free coating. figure 2 The picture on the left in the center shows the broken appearance of the existing metal aluminum pigment for spray-free coating. figure 2 The right side of the middle is the effect of the metal aluminum pigment for spray-free coating of the present invention being crushed under the same conditions. Apparently, the metal aluminum pigment particles for spray-free coating of the present inv...

preparation Embodiment 3

[0048] Adopt the raw material proportioning of embodiment 3 in the above-mentioned spray-free metal aluminum pigment formula table, promptly weigh the consumption of raw material:

[0049] Metallic aluminum pigment (35um) 75%, modified ABS resin 20%, diffusing powder 2%, mica 2% and Al 2 o 3 1%.

[0050] The steps for the preparation of the following spray-free metal aluminum pigments are the same as the steps of Preparation Example 1.

[0051] Such as image 3 Shown is a schematic diagram of the detection and comparison of metallic aluminum pigments for spray-free coating. image 3 The picture on the left in the center shows the broken appearance of the existing metal aluminum pigment for spray-free coating. image 3 The right side of the middle is the effect of the metal aluminum pigment for spray-free coating of the present invention being crushed under the same conditions.

Abstract

The invention disclose a spray-free metal aluminium pigment with embrittlement performance, and a preparation method thereof. The spray-free metal aluminium pigment with embrittlement performance is prepared from, by weight, metallic aluminum pigment 60% to 75%, epoxy resin 20% to 35%, diffusion powder 2% to 6%, and an embrittlement agent 3% to 5%. According to the preparation method, the embrittlement agent is added, so that after granulation and drying, the obtained pigment can be crushed more easily, the crushing time of the pigment in a pulverizer is shortened greatly, the shape of metal aluminum sheets in the spray-free metal aluminium pigment can be protected effectively, injection moulding product color difference is reduced, injection moulding product appearance is improved, production cost is reduced, and at the same time, the size of the crushed pigment is uniform, and mixing with plastic particles is more uniform.

Description

technical field [0001] The invention relates to the technical field of spray-free pigments, in particular to a spray-free metallic aluminum pigment with embrittlement performance and a preparation method thereof which can reduce the breakage time of the pigment. Background technique [0002] At present, the shells of home appliances and the interior parts of automobiles are usually sprayed with a layer of paint on the surface of plastic or metal parts to meet the different needs of consumers. However, most of the coatings on the market today contain volatile substances harmful to the body such as benzene and aldehydes. During the spraying process, these chemical substances will volatilize, which not only causes great pollution to the environment, but also causes great harm to the bodies of long-term spraying personnel. Especially when some high-end products are processed, the spraying process requirements are relatively high, which will inevitably lead to an increase in the...
