Embodiment 1-4 and comparative example 1-2

[0041] The formulations of Examples 1-4 and Comparative Examples 1-2 are shown in Table 1, and the units are parts by weight. Examples 1 to 4 are modified toners, antioxidants, dispersants, PA6, etc., mixed uniformly according to the proportion, then melt blended, extruded at 250 ° C, drawn, cooled with water, air-dried and pelletized to obtain modified Granules, injection molded into swatches at 250°C. Comparative examples 1 and 2 are prepared by mixing unmodified toner, antioxidant, dispersant, PA6, etc. according to the ratio, and then melt blending, extruding at 250°C, drawing, cooling in water, and air-drying to pelletize. Modified pellets, injection molded into color plates at 250°C.

[0042] The preparation method of the modified toner in Examples 1 to 4 includes: at room temperature, add melamine, m-phthalaldehyde and solvent to the reactor, stir to dissolve the solid powder completely, then add the pigment and continue to stir for 3-5min, and the reactor is heated C...

Abstract

The invention provides a low-frosting blue light red nylon material. The raw materials comprise 60%-80% of nylon, 20%-30% of glass fibers, 0.1%-0.5% of dispersing agents, 0.1%-0.5% of antioxidants, 0.1%-0.3% of lubricating agents and 0.3%-1% of modified toner. Under the condition that the original hue of the pigment is not changed, the natural color of the pigment is treated, the particle size of the pigment dye is enlarged, the possibility of precipitation of the pigment dye in a high-temperature environment is reduced, the frosting condition can be effectively improved, and meanwhile the frosting condition is further improved by adjusting an auxiliary system. After the nylon material provided by the invention is subjected to injection molding to form a product, the product is placed in a steam box to be steamed for 4 hours, and the product does not frost or fade.

Description

technical field [0001] The invention relates to the field of nylon material processing, in particular to a method for preparing low-blooming blue light red nylon material. Background technique [0002] There are many kinds of electric tools, and the application fields are very wide, which can involve almost all industries, and the market capacity is quite huge. With the continuous upgrading of the industry and the continuous expansion of the industrial scale, the output value of the electric tool industry has reached a level of 100 billion, and it is still growing. Early electric tools used cast iron as the casing, and later changed to aluminum alloy, and now thermoplastic engineering plastics are mainly used, and the double insulation of electric tools has been realized to ensure the safety of use. [0003] Among various thermoplastic engineering plastics, reinforced nylon is the best. Because nylon itself contains amide groups and has water absorption characteristics, ny...
