Abstract

The invention discloses a formula of strip copper gold powder. The strip copper gold powder is prepared from copper gold powder with mass percentage of 80-85% and a liquid medicine A with mass percentage of 15-20%, wherein, the liquid medicine A comprises the following components based on mass percentage: 18-30% of rosin glycerol resin and 70-82% of n-propyl acetate. The preparation method comprises the following steps: (1) mixing the rosin glycerol resin with the n-propyl acetate according to the mass percentage, and uniformly stirring to obtain the liquid medicine A; (2) pouring the liquid medicine A into the copper gold powder according to the mass percentage, uniformly stirring and infiltrating; and (3) putting the infiltrated copper gold powder in a molding press to be extruded into strips, and air drying to obtain the strip copper gold powder. The strip copper gold powder prepared by the method has the advantages that the powder does not contain benzene, methanol and ketone, thus the environmental protection requirement is improved; the dust pollution is avoided when a user uses the strip copper gold powder so as to improve production conditions of an operation workshop; the damage on top-grade printing equipment can be avoided; and the powder has low cost and is convenient for sale and transportation.

Description

technical field [0001] The invention relates to a copper-gold powder, in particular to a formula and a preparation method of a strip-shaped copper-gold powder, and belongs to the field of metal powder material production. Background technique [0002] At present, the copper gold powder on the market is widely used in coatings and printing industries such as flying gold, gold paint, handicraft coating, paper gold printing, plastic gold printing and rubber letterpress gold printing, so the market demand for copper gold powder is relatively large, but in production In the workshop, because the copper and gold powder is in the form of powder, it is easy to suspend in the air, causing dust pollution, which will affect the health of front-line production operators or fly into high-end printing equipment and cause damage. Simultaneously, because the powder object is bulky, it is extremely inconvenient to sell and transport, and it does not meet the requirements of environmental pro...
