Abstract
The utility model discloses a microprism type reflective membrane. The reflective membrane comprises a resin film layer, a microprism layer, a sealing membrane layer, a back adhesive layer and a piece of anti-sticking paper, wherein the microprism layer comprises a plurality of microprisms; and a plurality of concave structures or/and convex structures are arranged on the microprisms. According to the microprism type reflective membrane, unequal concave and/or convex parts are randomly arranged on the microprisms, the production yield rate is improved; and besides, the concave or convex parts serve as light-focusing points, so that the reflective efficiency is effectively improved.
Description
Technical field
The utility model belongs to reflective technical field of mold, relates to a kind of reflective membrane, relates in particular to a kind of micro-prism type reflective membrane.
Background technology
Reflective membrane is mainly used in guide plate, direction board, profile mark, the protuberant guide post of various highways and railway; Cone, crashproof tube, safety island, mine airport security board, place name sign, car plate, property sub-district safety notice, construction marker, billboard, scenery, trade mark etc.Because reflective membrane plays tangible warning function with its bright-coloured color by day, under the situation of night or insufficient light, its bright reflecting effect can strengthen people's recognition capability effectively; See target clearly, arouse vigilance, thereby avoid accident to take place; Reduce casualties; Reduce economic loss, become the indispensable security guard of road traffic, obvious social is arranged.
Introduce the purposes of engineering level, high intensity level and diamond reflecting film below.
1. engineering reflecting film
The engineering reflecting film is applicable to the traffic sign of Ordinary Rd, promptly common one-level, secondary, three grades, level Four road and the interim sign that uses.The commonly used work: fingerpost; Prohibitory sign, warning notice and Warning Mark and regular price-line advertising sign.Can adopt generic printing ink, use screen printing technique preparing various kinds pattern.Its life-span was generally 3～7 years.
2. high-strength reflecting film
High-strength reflecting film successfully is used for making traffic sign always.Even sign is regional than wide-angle situation and light, high-strength reflecting film all makes sign high-visible, predicts driver's road ahead dangerous situation effectively.
High-strength reflecting film is applicable to the traffic sign of Ordinary Rd, promptly common highway, one-level, secondary, three grades, level Four road and the interim sign that uses.Be usually used in: fingerpost; Prohibitory sign, warning notice and Warning Mark and regular price-line advertising sign.Its life-span was generally 10 years.Under normal behaviour in service, the retro-reflecting coefficient retention after 10 years is at least 80% of initial retro-reflecting coefficient value.
3. diamond reflecting film
The diamond reflecting film is applicable to the traffic sign of high-grade highway and urban road.Be mainly used in: fingerpost, prohibitory sign, warning notice and Warning Mark.Adopt generic printing ink and use the screen printing technique can the preparing various kinds pattern.Its life-span was generally 10 years.Under normal behaviour in service, the retro-reflecting coefficient retention after 10 years is at least 80% of initial retro-reflecting coefficient.
Closely during the last ten years, the production technology develop rapidly of China's reflective membrane, multinomial reflectorized material has all had independent intellectual property right; Economy, engineering level, high-strength reflecting film have formed product line, and automotive number plate is also produced in enormous quantities with reflective membrane and truck reflecting marking reflective membrane; Not only substituted import, also exported to foreign countries.
The three big technical barriers of producing reflective membrane are material, equipment and technology.
The main material resin of reflective membrane, pigment, glass microballoon are most important to the reflective membrane Effect on Performance.Wherein, resin should have good coating, cementability, compatibility and weatherability etc., and the resin of top layer and focus layer must have good light transmittance.For pigment, should be bright in luster, form and aspect are stable, also want transparency height and and resin compatible.And glass microballoon particle diameter 35～90 μ m only are much thinner than people's hairline; Require granularity rounding, devitrification rate low, refractive index and size distribution rate height.
The production equipment of domestic reflective membrane is formed production line mostly, and can realize connecting machine, the operation of group line according to technological requirement.Coating, composite production line all adopted frequency conversion, synchronously, correction, the regulation and control of permanent tension force; The drying tunnel temperature separated regions is accurately controlled; Coating and rolling station are realized the constant temperature operation basically.
The technological level of domestic reflective membrane is basically near world level.Should be pointed out that especially some enterprise is only with planting the difficult problem that the pearl mode has just solved the glass microballoon single-layer coplanar tree, has been evenly distributed easily.But present domestic diamond reflecting film still is in development, trial production stage; The occupation rate of homemade high-strength reflecting film on highway is also lower; The independent research and development capacity of homemade reflective membrane, production technology and product quality are still waiting further raising.
The structure of reflective membrane is divided into three types of lens baried type, seal capsule type and micro-prism types.The structure of ultra engineering level, engineering level, economic reflecting film is the lens baried type, and the structure of high-strength reflecting film is the seal capsule type, and diamond reflecting film structure is a micro-prism type.
After each micro-crystal cubic body of diamond reflecting film combines to arrange, at the micro-crystal cubic angle body that has on the material area of a square centimeter more than 930.Micro-crystal cubic angle body lower floor forms an air layer after sealing, make incident ray form inner full-reflection, thereby do not need can reach superior reflecting effect by metallic reflector.The diamond reflecting film and traditional engineering level and comparison of high strength reflecting film that use high rigidity, wear-resisting polycarbonate material and micro-crystal cubic body technique to process, its reflective function not only is multiplied, and wide-angle performance also improves a lot.
Yet the production yield of existing diamond reflecting film is lower, and simultaneously, existing diamond reflecting film structure makes that the reflector efficiency of reflective membrane is low.
The utility model content
The utility model technical matters to be solved is: a kind of micro-prism type reflective membrane is provided, can improves the production yield of product, can effectively improve reflector efficiency simultaneously.
