Abstract
A high-strength glass fibre reinforced plastic light baffle-board mainly includes two layers of glass fibre reinforced plastic skin and a preset mounting embedded part, a high-density polyurethane which is added. The high-density polyurethane is filled between the two layers of glass fibre reinforced plastic skin after foaming and molding. The utility model has the advantages of high mechanical intensity, good reflection effect, light weight, low cost and high work efficiency, so the utility model has strong market competitiveness.
Description
Technical field:
The utility model relates to a kind of fiberglass light reflecting plate, and the fiberglass light reflecting plate that particularly a kind of outdoor illumination uses belongs to the laminar product field.
Technical background:
Can directional lighting for the light that makes outdoor lighting, all the light reflecting plate of directional illumination need be installed above electric light.Existing fiberglass light reflecting plate is to paste frp layer by two one-side moulds, interior with batten or bonding jumper the junction is reinforced after, two-sided matched moulds forms the hollow type constructed products.More quality problems have appearred in this product in actual use, at first are in order to guarantee the production cycle, and frp layer is will the demoulding before not solidifying fully, makes the product surface appearance uneven; Second, because of the batten of liner or bonding jumper are reinforced junction at the layer glass steel, and batten or bonding jumper are all different with the coefficient of thermal expansion and contraction of fiberglass, after product is thrown off from mould, the stiffness height of footing, the stiffness of fiberglass part is low, product unbalance stress when continuing to solidify, the flatness of product is destroyed, badly influenced the reflective function of product; The 3rd, what this plate adopted is on an empty stomach to mold technique, be subjected to the influence of process conditions, the binding site of product is the end face contact during to mould, contact-making surface only has the edge contact of 2-3MM, mechanical strength is low, be easy to generate cracking even fracture, add the solar radiation on daytime and the light-illuminating at night is penetrated plate in turn respectively to reflection the upper and lower heating, the end face cracking that the further aggravation of meeting is in contact with one another and the flatness of reflector face, personal injury is very easily caused on the ground of will degenerating when can't stand the pressure of strong wind; The 4th, this product is because of being hollow-core construction, though in light weight many than solid glass steel construction, the thickness of every layer of fiberglass still needs about 3MM, still reach the 5-15 kilogram for basic size 0.5-1.5 square metre large product weight, the mechanical strength of lamp stand is also had relatively high expectations; The 5th, because the specific (special) requirements of product, the shape of light reflecting plate can be designed to multiple shapes such as curved surface, hyperboloid, disc or sphere, make the batten of footing or bonding jumper also will be prefabricated into and be connected the inboard corresponding shape of end face, make complex manufacturing, production efficiency low according to design.
Summary of the invention:
The purpose of this utility model is in order to overcome the weak point of above-mentioned fiberglass light reflecting plate, the intensity that designs a mechanism height, the high strength glass fiber reinforced plastic light reflecting plate that reflecting effect is good, in light weight, cost is low, production efficiency is high.
Technical measures of the present utility model mainly are cancellation batten or bonding jumper girth members and enhancing productivity, and further reduce the thickness of frp layer and weight reduction and reducing cost, and are locating the filling foamed plastic and are improving mechanical strength and flatness in empty stomach.Its structure mainly comprises layer glass steel covering and the installation built-in fitting that presets, and also includes the high density polyurethane, and described high density polyurethane is filled between the layer glass steel covering through foaming and molding.
High strength glass fiber reinforced plastic light reflecting plate of the present utility model has the mechanical strength height, reflecting effect is good, in light weight, cost is low and the production efficiency advantages of higher, has the very strong market competitiveness.
Description of drawings:
Accompanying drawing 1 is a structural representation that embodiment is a S shape plate of the present utility model;
Accompanying drawing 2 is that the A-A of accompanying drawing 1 is to cross-sectional view;
Accompanying drawing 3 is second structural representation that embodiment is a Da Yan shape plate;
Accompanying drawing 4 is that the A-A of accompanying drawing 3 is to cross-sectional view;
Accompanying drawing 5 is that the 3rd embodiment is the structural representation of arc;
Accompanying drawing 6 is that the A-A of accompanying drawing 5 is to cross-sectional view.
The specific embodiment:
Because the light reflecting plate can be designed to multiple shape as required, but its structure all is the same, by layer glass steel covering and installation built-in fitting and high density polyurethane are formed up and down, accompanying drawing provides is the structural representation of several practical shapes, describe in further detail below in conjunction with accompanying drawing, accompanying drawing 1,3,5, it is the structural representation of the high strength glass fiber reinforced plastic light reflecting plate of several simple shapes, among the figure 1 is the fiberglass covering, the 2nd, the installation built-in fitting that being used in the high density polyurethane between the layer glass steel covering that presets fixedlys connected with lamp stand, this installs built-in fitting can use steel plate, copper coin, alloy aluminium sheet or other metallic plate are made, can preset bolt hole on the built-in fitting, but bore also tapping when also non-bolt also and is at the scene installed.Accompanying drawing 2,4,6 be respectively the A-A of accompanying drawing 1,3,5 to cross-sectional view, 2 among the figure installs built-in fitting, the 3rd, upper strata fiberglass covering, the 4th, lower floor's fiberglass covering, the 5th, high density polyurethane.During production, in the open-close module of the various types that presets, smeared mould release wax, paste and solidify after glass cloth makes it to reach 1-2MM covering layer, put the installation built-in fitting well through preliminary finishing corner with in the precalculated position, bonding minute land area, and carry out matched moulds, and forming empty stomach product by mould control, the reserved passageway by mould injects the about 120KG/M of density again
3High density polyurethane, foaming in the empty stomach product, and the temperature in the die cavity is reached about 120 ℃ can also produce 2KG/CM
2Pressure is improved the curing degree of fiberglass part, and simultaneously, the polyurethane resin used because of the glass cloth that pastes fiberglass belongs to binding material together with foaming polyurethane partly, the coefficient of thermal expansion and contraction basically identical, and the overall performance after compound is splendid.Because of fiberglass covering layer has formed bigger surface tension and very high rigidity, and high density polyurethane is greatly improved mechanical performance of products except higher intensity being arranged and preferably the toughness, can also making product have good internal stress.Since this product have best bright finish, high-flatness, high strength, in light weight, be convenient to supporting user, also can make the user bring benefit on the lamp stand basis with aspect saving energy and reduce the cost for a long time, have the stronger market competitiveness.
