In recent years, lead-containing materials has a wide range of applications in industry, and its toxicity affects the mankind and other biology day by day.The lead of a large amount of at present high pollutions of using, high toxicity, low-intensity, low usefulness will be eliminated rapidly; And the tungstenic material of high comprehensive performance, environment-protecting asepsis will be optimal substitution material.Tungsten (or tungsten alloy) powder/nylon 6 composite material has good high-energy ray screening ability, but is that tungsten powder or its alloyed powder that nylon 6 (PA6) engineering plastics that injection moulding is extruded coat difficult moulding is prepared from.This composite is good high-energy ray shielding material; X ray, gamma-rays and radio isotope radiation had excellent decay and absorbability; Can be suitable with lead, have potential application in fields such as medical science diagnosis and treatment, nuclear energy uses, article safety check, industrial flaw detections.Yet tungsten (or tungsten alloy) powder/the nylon 6 composite material structural strength is not high, has limited its range of application.
Summary of the invention
The utility model technical problem to be solved provides a kind of leadless environment-friendly high-energy ray shielding composite plate, can overcome single tungsten (or tungsten alloy) shortcoming that powder/the nylon 6 composite material structural strength is not high, and alternative lead is done radiation proof, anti-shielding material.
The utility model solves the technical scheme that its technical problem adopted: a kind of leadless environment-friendly high-energy ray shielding composite plate is provided, comprises the shielding material layer, also comprise the structure aluminium lamination; Be fixed with said shielding material layer on said structure aluminium lamination one side surface.
Have groove on said structure aluminium lamination one side surface, described shielding material layer is entrenched in the said groove; The telescoping part of said shielding material layer and said structure aluminium lamination forms binder course.
Said shielding material layer is the nylon 6 engineering plastic layer that is coated with tungsten powder or tungsten alloy powder.
Beneficial effect
Owing to adopted above-mentioned technical scheme; The utility model compared with prior art; Have following advantage and good effect: the utility model utilizes the high temperature plasticity and the structure aluminium sheet of tungsten (or tungsten alloy) powder/nylon 6 composite material compound; Make full use of the shielding properties of composite and the strength advantage of structure aluminium, efficiently solved single tungsten (or tungsten alloy) problem that powder/the nylon 6 composite material structural strength is low.Wherein, tungsten (or tungsten alloy) powder/nylon 6 composite material Mi Du ≧ 10.0g/cm3, shielding properties is with quite plumbous, and radiation resistance is good.
Description of drawings
Fig. 1 is the structure cutaway view of the utility model.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction the utility model scope.Should be understood that in addition those skilled in the art can do various changes or modification to the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
The embodiment of the utility model relates to a kind of leadless environment-friendly high-energy ray shielding composite plate, and this composite plate can be processed into parts easily.The structure of the utility model is as shown in Figure 1, is fixed with shielding material layer 3 on the side surface of structure aluminium lamination 1, and this shielding material layer 3 is high density tungsten (or tungsten alloy) powder/nylon 6 composite material layer.The high-energy ray shielding composite that is adopted; Be but that tungsten powder or its alloyed powder that nylon 6 (PA6) engineering plastics that injection moulding is extruded coat difficult moulding is prepared from; That is to say that shielding material layer 3 is for being coated with the nylon 6 engineering plastic layer of tungsten powder or tungsten alloy powder.In order to make structure aluminium lamination and shielding material layer more firm, have groove on said structure aluminium lamination 1 one side surfaces, described shielding material layer 3 is entrenched in the said groove; Said shielding material layer 3 forms binder course 2 with the telescoping part of said structure aluminium lamination 1.
What this product was realized is to adopt certain pressure, with tungsten (or tungsten alloy) powder/nylon 6 composite material at a certain temperature, by structure chimeric with absorption affinity attached on the structure aluminum component.This leadless environment-friendly high-energy ray shielding composite plate, the high-energy ray screening ability is strong, can be processed into various parts, is used for detecting chemical industry, security, fields such as medical treatment, nuclear industry.
Tungsten (or tungsten alloy) powder/nylon 6 composite material prepares as follows; At a certain temperature; Adopt mechanical agitation that tungsten (or its alloy) powder and coupling agent ethanolic solution are fully mixed certain hour, the tungsten that will handle then (or its alloy) powder in baking oven 90 ℃ dry 4-20 hour.In temperature is between 220-260 ℃, and above-mentioned tungsten (or its alloy) powder, nylon 6 particles and antiradiation additive etc. at the mixing device melt blending, are prepared tungsten (or tungsten alloy) powder/nylon 6 composite material; Between 220-260 ℃, be squeezed into leadless environment-friendly high-energy ray shielding composite plate then, form shielding composite plate as shown in Figure 1 with the structure aluminium sheet.
Be not difficult to find; The utility model utilizes the high temperature plasticity and the structure aluminium sheet of tungsten (or tungsten alloy) powder/nylon 6 composite material compound; Make full use of the shielding properties of composite and the strength advantage of structure aluminium, efficiently solved single tungsten (or tungsten alloy) problem that powder/the nylon 6 composite material structural strength is low.Wherein, tungsten (or tungsten alloy) powder/nylon 6 composite material Mi Du ≧ 10.0g/cm
3, shielding properties is with quite plumbous, and radiation resistance is good.
By on can know that the utility model is an a kind of leadless environment-friendly high-energy ray shielding composite plate, its advantages of good shielding performance, good mechanical performance, and processing; Can be widely used in fields such as medical treatment, security, chemical industry, nuclear industry, and not contain lead, be a kind of shielding composite board of green, has practical preferably prospect.
