Embodiment
[0019] combine figure 1 and figure 2 This embodiment will be described in detail. The integral molding production process of an anti-glare diffuser plate involved in this embodiment includes four steps in sequence: raw material pretreatment, melt extrusion, sheet forming, and traction cutting.
[0020] In the raw material pretreatment step, the raw material is placed in the light material machine, and the dust and large particles in the raw material are initially separated to avoid the influence of dust and large particles on the subsequent process steps. The temperature and time required for pre-crystallization and heat melting are inconsistent with other granular raw materials. The processed raw material is sent to a pre-crystallizer, and the raw material is fully dried and crystallized, so that the water content of the dried raw material is below 0.01%. In this step, the drying temperature is 155-160° C., and the drying time is 2-3 hours, so that the moisture content of...

The invention discloses an anti-dazzle diffusion plate integrated forming production process. The anti-dazzle diffusion plate integrated forming production process sequentially comprises raw materialpretreatment, melt extrusion, sheet material forming and traction cutting. The raw material pretreatment comprises the following step of carrying out preliminary separation and pre-crystallization onthe raw materials. The melt extrusion comprises the following steps of heating and melting raw materials, and extruding through a diffusion mold and an anti-dazzle mold; the sheet material forming comprises the following steps of cooling and forming through a cooling mold so as to obtain an anti-dazzle diffusion plate sheet material; and the traction cutting comprises the following steps that thesheet material is dragged through a traction machine, so that the sheet material is flat and is cut according to the required size. According to the anti-dazzle diffusion plate integrated forming production process, the fused raw materials are extruded through a diffusion mold and an anti-dazzle mold, so that the anti-dazzle diffusion plate is integrally formed, the diffusion plate and an anti-dazzle plate are replaced, an illuminating device does not need to be additionally provided with the diffusion plate, the cost of the illuminating device can be reduced, and the weight of the illuminating device can be reduced.
Description
technical field [0001] The invention relates to the technical field of anti-glare plate production, in particular to an integrated molding production process of an anti-glare diffusion plate. Background technique [0002] In the traditional sense, a lighting device that can reduce glare includes a panel light source, a reflector, a light guide plate, a diffusion plate, and an anti-glare plate. The anti-glare plate in this lighting device includes an anti-glare microstructure and a transparent substrate. The arrangement of the diffusion plate and the anti-glare plate can make the production cost of the illuminating device with this arrangement relatively high, and the weight is also relatively large. Contents of the invention [0003] The purpose of the present invention is to provide an integrated production process for the anti-glare diffuser plate, so that the diffuser plate and the anti-glare plate are integrally formed without additional assembly of the diffuser plate....
