Abstract
The present invention relates to a making technologic process of calendered and ground organic glass plate material. The process adopts high roller temperature, roller linear speed and a continuous producing technology organically matched with the roller temperature. The process overcomes the defects of low automatic degree, low yield and high producing cost of calendered and ground organic glass plate material produced by a casting method, and also overcomes the defects of calendering disappearance and poor grinding due to conventional extruding molding. Compared with a traditional technology, the producing cost of the calendered and ground organic glass plate material molded by extrusion in one step by the present invention is reduced by 50%; the yield is enhanced by 50%. The present invention can be applied to the decorative field of illuminating lamp appliances.
Description
The present invention relates to a kind of methacrylate sheet method of manufacturing technology, particularly a kind of making process of calendered and ground organic glass plate.
Calendered and ground organic glass plate has cast and extrudes two kinds of moulding techniques at present, and the sheet material molecular weight that the former produces is higher, stable physical property, frosted finish effect is good, but this method needs great amount of manpower and material resources, and human factor is higher, causes the product thickness inequality easily, the cost height, limitation such as yield poorly be difficult to adapt to the market of develop rapidly, and the latter can produce continuously, the output height, cost is relatively low.Yet, calendered and ground organic glass plate, because of being widely used in lighting, decorates good inferior photosensitiveness, but illumination needs secondary operations usually with sheet material, i.e. thermoforming is to the inferior tarry matter sand plate of the extrusion molding of routine, because temperature is usually at 80-100 ℃ during its typing, cause inferior light to disappear so add thermoforming meeting in man-hour, frosted finish effect is poor, does not reach the requirement of the lighting decoration of inferior tarry matter sand.Chinese patent CN97108817 has introduced " a kind of high-scattering light-conducting organic glass and preparation method thereof ", and this patent also is to adopt the method for cast, the same difficult point of artificial control and the discontinuity of production of existing.
The inferior photosensitiveness that not only can keep when the object of the present invention is to provide a kind of calendered and ground organic glass plate machine-shaping but also can the quantity-produced making process of calendered and ground organic glass plate.
The object of the present invention is achieved like this: higher roller temperature is set, the continuous production processes of roller linear velocity and the organic coupling of roller temperature, its processing step is as follows: material preheater---extrudes---cooling and shaping---detection---traction---pad pasting---scale cutting---packing, the preheating time and the temperature that it is characterized in that material were respectively 3 hours, 230-300 ℃, change over to and extrude that to keep extruding the gear pump rotating speed be 600-800rpm, sheet material is by last, in, following three roller temperature scopes are respectively: top roll 90-110 ℃, central roll 140-180 ℃, lower roll 70-90 ℃.
The invention has the beneficial effects as follows: higher roller temperature, the continuous production processes of roller linear velocity and the organic coupling of roller temperature are set owing to adopt.Overcome the calendered and ground organic glass plate automaticity that pouring procedure produces not high, yield poorly, the defective of production cost height, contaminated environment causes inferior light to disappear the defective of frosted difference when having overcome conventional extrusion modling again.Adopt the calendered and ground organic glass plate of an extrusion modling of the present invention, production cost reduces by 50% than traditional handicraft, and output improves 50%.
Embodiment 1: the calendered and ground organic glass plate of producing 3mm, its processing step is: material preheater---extrudes---cooling and shaping---detection---traction---pad pasting---scale cutting---packing, the preheating time of material and temperature are respectively 3 hours, 240-270 ℃, change over to and extrude that to keep extruding the gear pump rotating speed be 700rpm, sheet material is respectively by three the roller temperature scopes in upper, middle and lower: top roll 100-105 ℃, central roll 160-170 ℃, lower roll 80-90 ℃.All the other are common process.
Embodiment 2: the calendered and ground organic glass plate of producing 3mm, its processing step is: material preheater---extrudes---cooling and shaping---detection---traction---pad pasting---scale cutting---packing, the preheating time of material and temperature are respectively 3 hours, 250-280 ℃, change over to and extrude that to keep extruding the gear pump rotating speed be 750rpm, sheet material is respectively by three the roller temperature scopes in upper, middle and lower: top roll 90-100 ℃, central roll 165-175 ℃, lower roll 80-85 ℃.All the other are common process.
