Embodiment 1

[0025] First, spray the deionized aqueous solution (30g / l, solution temperature: 30℃) of the prepared washing powder evenly on the surface of the resin model with a spray gun, clean the slush mold into the slot mold, and then spray the deionized water with the spray gun to rinse the residual Cleaning solution, the temperature of deionized water is 23°C;

[0026] Next, spray a wetting solution (30°C) on the cleaned surface. The mixed solution of deisopropanol and hydrophilic treatment agent HYDRO310 is the wetting solution. After staying for 1 minute, spray deionized water with a spray gun to clean the residual wetting solution. The temperature of deionized water is 23°C;

[0027] Again, the silver ammonia solution A (silver nitrate 5g / l) that has been configured and reducing agent B liquid are simultaneously sprayed onto the surface of the groove mold after wetting with a double-headed spray gun to form a bright and dense silver layer. The spray gun pressure is 0.5 Mpa, the d...

[0033] First, spray the deionized aqueous solution (35g / l, solution temperature: 30°C) of the prepared washing powder evenly on the surface of the resin model with a spray gun, clean the slush mold into the slot mold, and then spray the deionized water with the spray gun to rinse the residual Cleaning solution, the temperature of deionized water is 23°C;

[0034] Next, spray a wetting solution (32°C) on the cleaned surface. The mixed solution of deisopropanol and hydrophilic treatment agent HYDRO310 is the wetting solution. After staying for 3 minutes, spray deionized water with a spray gun to clean the residual wetting solution. The temperature of deionized water is 23°C;

[0035] Once again, the configured silver ammonia solution A (silver nitrate 10g / l) and reducing agent B liquid are sprayed onto the surface of the grooved mold after wetting simultaneously with a double-headed spray gun to form a bright, dense silver layer. The spray gun pressure is 0.5Mpa, the distance i...

Abstract

The invention belongs to the field of automobile instrument panels, and relates to a conductive treatment method for an inlet groove mould surface of a slush moulding mould. The conductive treatment method comprises the following steps: 1, cleaning the inlet groove mould surface by using a mixed solution of deionized water and washing powder; 2, rinsing the residual cleaning solution by spraying the deionized water through a spray gun; 3, wetting the inlet groove mould surface by using a mixed solution of isopropanol and a hydrophillic treatment agent HYDRO310; 4, rinsing the residual wetting solution by spraying the deionized water through the spray gun; 5, preparing a diaminesilver solution A and a reducing agent solution B; 6, silvering the inlet groove mould surface by using a double-head spray head; 7, cleaning the inlet groove mould surface by spraying the deionized water through the spray gun. In the conductive treatment method, a sensitization process is avoided, and in the preparation process of the diaminesilver solution, an alkaline solution is not used, and a silver mirror can be directly sprayed on the cleaned and wetted surface, so that the conductive treatment method is simple and low in cost; a formed silver layer is bright, dense, good in conductivity and unlikely to shed off, so that the requirement on conduction of the inlet groove mould surface of the large-sized slush moulding mould can be met.

Description

technical field [0001] The invention belongs to the technical field of automobile instrument panels, and relates to a surface conduction treatment method for a slush mold into a slot die, in particular to a surface conduction treatment method for an automobile instrument panel slush mold into a slot die. Background technique [0002] The large-scale slush molding mold for automobile instrument panel requires realistic simulation effect of surface patterns, so the requirements are very high in the later stage of conductive treatment of the resin mold in the groove. Avoid acid and alkali corrosion during treatment, otherwise it will cause the resin to decompose and cause the pattern to be distorted. On the other hand, the conductive treatment process is complicated by using the traditional silver mirror reaction. For example, the patent CN102808177A provides an epoxy resin The resin-based composite conductive layer is first chemically silver-plated, and then nickel-plated on i...
