Abstract
The utility model relates to a photon reflection composite film which is characterized in that TYVEK paper is symmetrically adhibited on two sides of a PE film through adhesive. According to the photon reflection composite film, through laminating combination, a polyethylene film is well adhibited with TYVEK paper, thereby forming a novel film structure with symmetry. The photon reflection composite film has the following advantages: high strength, high tearing resistance, smooth surface, high water resistance, high acid-base resistance, electrostatic prevention performance, high wearing resistance, high aging resistance and high perpendicularity.
Description
Technical field
The utility model belongs to the material field, especially a kind of photon reflection composite membrane.
Background technology
The utility model is mainly used in the test of high-energy physics space particle, be used for Daya Gulf neutrino experiment engineering, the photon of generation when hydrogen nuclei bumps in neutrino that nuclear reactor produces and the water, can reflect 99% photon through reflectance coating, amplify analysis by photon signal is entered computer, thereby find the oscillation mode of new neutrino.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, the photon reflection composite membrane is provided, and the reflective film material of the utility model preparation has characteristics such as high strength, in light weight, soft, level and smooth, difficult fluffing, anti-water, antiacid alkali, antistatic, folding, wear-resistant, ageing-resistant, suitable environmental protection.
The purpose of this utility model is achieved through the following technical solutions:
A kind of photon reflection composite membrane, the consisting of of material: TYVEK paper is bonded in the both sides of PE film by the adhesive symmetry.
And the glue-spread of described adhesive is 3-20g/ ㎡.
And the thickness of described PE film is the 50-150 micron.
And the thickness of described photon reflection composite membrane is: 0.55-0.75mm.
Advantage of the present utility model and beneficial effect are:
1, the utility model is compound by lamination, polyethylene film and TYVEK well are bonded together, form a kind of new symmetric film equipment structure that has, this laminated film has that intensity height, resistance to tearing are good, surfacing, anti-water, antiacid alkali, antistatic, wear-resistant, ageing-resistant, sag is good.
2, the utility model positive and negative of preparing reflectance coating has the identical reflectivity to photon, reflectivity to photon in air reaches 98%, reach more than 99% in the water, make neutrino through in the water with water in the hydrogen nuclei photon that bumps and produce, can be to the reflectivity of photon more than 99% through reflectance coating, and photon amplifies by photomultiplier and becomes data signal through converter and enter computer and calculate and amplify to analyze, thereby find the oscillation mode of new neutrino, huge contribution is made in new scientific discovery.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.
Raw material of the present utility model are that the TYVEK of individual layer is the polyolefine fiber goods that du pont company is produced, but the TYVEK film of individual layer to the reflectivity of photon about 70%, the sag difference can not satisfy the neutrino experiment requirement, therefore needs to improve reflectivity and the sag of film.
The utility model is by being bonded together TYVEK paper and PE film under the effect of heat and pressure, make a kind of neither cloth, paper/cloth type the nonwoven that neither plastic sheeting but has paper, cloth and three kinds of advantages of film, have high strength, in light weight, soft, level and smooth, be difficult for characteristics such as fluffing, anti-water, antiacid alkali, antistatic, folding, wear-resistant, ageing-resistant, suitable environmental protection.
The utility model photon reflection composite membrane is three-layer combined structure, and as described in Figure 1, thickness is: 0.65mm, structure is: TYVEK paper logical 1 is crossed the both sides that adhesive 2 symmetries are bonded in PE film 3.Wherein TYVEK paper is the product of du pont company, model is 1082D, the thickness of PE film is that the 50-150 micron all can, present embodiment adopts 100 microns, adhesive is two component anti-boiling and anti glue sticks (two component boiling resistant polyurethane composite adhesives, this adhesive is adhesive well known in the art, does not have particularity), glue-spread is 3-20g/ ㎡, and colloidal solids content is controlled at 20-35%.
The requirement that the physical and chemical parameter of PE film need satisfy is:
1. hot strength/MPa portraitlandscape is more than or equal to 30;
2. elongation at break (%) portraitlandscape is more than or equal to 500.
Adhering method is: with the even smooth adhesive coating in PE film both sides, be 3-20g/ ㎡ with glue-spread; The back side of TYVEK paper evenly is bonded in PE film both sides; Flat surface gets final product.
After testing, the physical and chemical parameter of above-mentioned photon reflection composite membrane is as follows:
100 ℃ of not delaminations in 30 minutes of poach;
Thickness is: 0.65mm;
The physical and chemical parameter of table 1 photon reflection membrane material
