As a further improvement on the present invention, described continuous glass fibre is an alkali free glass fibre, and its diameter is 10～25 μ m.
As a further improvement on the present invention, described toughner is ethylene-propylene acid butyl ester-glycidyl methacrylate copolymer.
As a further improvement on the present invention, described carbon black is the powder with strong black opacifying power.
As a further improvement on the present invention, described nucleator is the saturated carboxylic acid sodium salt of linear long-chain.
As a further improvement on the present invention, described laser marking additive is to have the white powder that strengthens resin combination laser labelling function.
The present invention also provides a kind of preparation method with PET resin combination of laser labelling function, and its concrete steps are:
1. example takes by weighing polyethylene terephthalate, toughner, nucleator, laser marking additive and carbon black by weight percentage;
2. with above-mentioned load weighted polyethylene terephthalate, toughner, nucleator, enter twin screw extruder behind laser marking additive and the carbon black uniform mixing, add continuous glass fibre in the 6th district, forcing machine middle part, the content of this continuous glass fibre is controlled by regulating forcing machine rotating speed and feeding rotating speed, control a district temperature 230-250 ℃ simultaneously, two district temperature 230-250 ℃, three district temperature 240-260 ℃, four district temperature 240-260 ℃, five district temperature 240-260 ℃, six district temperature 240-260 ℃, seven district temperature 240-260 ℃, eight district temperature 240-260 ℃, nine district temperature 240-260 ℃, engine speed 300-400 rev/min;
3. extruding cooling, drying, pelletizing gets product.
The invention has the beneficial effects as follows: employing laser marking additive as the performance enhancement component, is prepared a kind of resin combination that has better mechanical property and laser labelling performance simultaneously as laser labelling enhancing ingredients, continuous glass fibre.This PET resin combination can form white text at the black product surface, perhaps forms distinct laser labellings such as black literal at white product surface, has kept the high performance nature of PET resin combination when having laser labelling function preferably.
Embodiment
Below in conjunction with embodiment, the present invention is described in further detail:
Matrix resin PET resin selects that engineering plastics factory of Yizheng branch office of assets management Management Co., Ltd of SINOPEC produces for use commonly has a light slicing product; Continuous glass fibre adopts the thermoplastics assembled roving of Chinese megalith group preparation, and the trade mark is 988A.Toughner adopts the ethylene-propylene acid butyl ester-glycidyl methacrylate copolymer (PTW) of du pont company; Nucleator employing section is a kind of long-chain linear saturated carboxylic acid sodium salt of benefactor department how, and the trade mark is NAV101; Carbon black is that Shanghai Yanrun Ray Machine Technology Co., Ltd. produces, and the trade mark is C-311; The laser marking additive is that DSM N. V. produces, and the trade mark is Micabs A206.
