Abstract
The invention provides a laser marking aid for polyamide plastics, a preparation method for the laser marking aid and application of the laser marking aid. The laser marking aid for the polyamide plastics is characterized by containing the following components in percentage by weight: 55 to 75 percent of hydroxide, 10 to 35 percent of tin oxide, 0.5 to 8 percent of talcpowder, 0.5 to 4 percent of metal antimony, 0.5 to 8 percent of halogen-free flame retardant and 0.5 to 4 percent of lubricant. The preparation method comprises the following steps of: uniformly mixing the tin oxide and the metal antimony by ultrasonic waves or a high-efficiency dispersion machine under the condition that the lubricant is added; and adding the hydroxide, the talcpowder and the halogen-free flame retardant into the mixture, and mixing uniformly. When the laser marking aid is used for plastic manufacture, the adding amount is 0.5 to 20 weight percent. A dark marker with obvious contrast can be formed on the light plastic surface by performing laser printing after the laser marking aid is added into polyamide resin, and adverse phenomena can be avoided; and the laser marking aid can be widely applied in the fields of manufacture of shells of low-voltage electric appliances and the like.
Description
Technical field
The present invention relates to a kind of additive of modifying plastics, particularly a kind of auxiliary agent that is used for laser labelling and preparation method thereof.
Background technology
Laser labelling is a kind of industrialized marking method, has advantages such as quick, efficient, all is widely used at industry-by-industry.A basic demand of laser labeling method is exactly behind mark, to produce enough effect clearly in material surface.But that on the different resins base material, carries out laser marking is difficult to the degree difference, because different plastics have the different laser S. E. A..Some plastics is easy to mark because be prone to absorb energy; Some plastics does not then absorb laser, can not generate mark with laser at all.The specific absorption of laser energy is the function of wavelength, and therefore, under the effect of same laser intensity, different plastics can obtain the mark of Different Weight.For example, some coloured high density polyethylene(HDPE)s and polycarbonate need not add any additives and just can obtain the ideal marking with the YAG laser apparatus time; And the employing CO 2 laser marking machine just prints bad if do not add special additive.In addition, the cavity on the degraded of plastics, slight crack, surface etc. also can cause mark weight to reduce.Polymeric amide and compsn thereof relate to the laser marking requirement as a kind of engineering plastics in a lot of industries.For polyamide material, itself is not strong to the incident laser absorption, so under the laser energy irradiation; Plastics are difficult for generating mark, but after the energy increase, can generate mark at material surface; But the edge of the marking can thicken behind the laser labelling; Still can take place to obtain trace clearly, phenomenons such as marking contrast gradient deficiency that obtains or the jaundice of marking color, thus can't satisfy mark requirement clearly.
In order to solve above-mentioned technical problem, many inventions about laser labelling have been arranged at present so that terms of settlement to be provided.But these inventions all are the methods of coming material is carried out laser labelling in the method that adds the laser auxiliary agent, mainly are to utilize the energy of laser radiation to make material carbonization variable color realize the marking of laser labelling.Yet, still can there be the phenomenon that the edge of the marking can thicken behind the laser labelling, still can't obtain the good mark of sharpness.
Summary of the invention
The objective of the invention is to overcome in the prior art in the surperficial problem that produces the tangible dark mark of contrast through the method for laser labelling of polyamide plastics.
In order to achieve the above object; The invention provides a kind of laser mark auxiliary agent that can on the polyamide resin matrix of light colour, realize the dark colour mark; After being added on it in polyamide plastics; Can on the light-colored resin matrix, realize contrasting tangible dark mark through laser labelling, it is characterized in that, comprise following raw material by weight percentage:
