Embodiment Construction
[0039] The present invention will be further described by referring to the accompanying drawings below through the description of specific embodiments;
[0040] One of a typical specific implementation manner, as attached Figure 1-7 shown.
[0041] A trough-type solar thermal power generation concentrating reflector component, including a thin-walled glass reflector 1 with a curved surface to collect light and coated with a reflective layer, and a rear protection that matches the glass reflector 1 and is sealed and fixedly connected with a distance. The shell 2 and the polyurethane foam material layer 3 arranged in the cavity between the glass reflector 1 and the rear protective shell 2, in the polyurethane foam material layer 3, contain a standing glass fiber three-dimensional net Lattice core woven fabric 4;
[0042] And the thickness of the polyurethane foam material layer 3 is in the range of 30 ~ 100mm;
[0043] And the rear protective shell 2 is made of glass fiber r...

The invention discloses a solar concentrating reflector component and a preparation method thereof. The concentrating reflector component is mainly used for solar thermal power generation, and its finished product consists of a glass reflector 1, a rear protective shell 2 and polyurethane hair. The foam material layer 3 is composed of the foam material layer 3, and the glass fiber three-dimensional mesh core material woven fabric 4 is contained in the foam material layer 3 as the main feature, and its preparation method includes preparing the rear protective shell in sequence, and laminating the glass reflector On the male mold, there are 6 steps including bonding the glass fiber three-dimensional grid core material woven fabric in the female mold, combining the mould, injecting polyurethane foam material and shaping. The finished product has the characteristics of light weight, high reflectivity, long service life, etc., and its preparation method is simple, reasonable, easy to control, and the like.
Description
technical field [0001] The invention relates to a solar concentrating reflector component and a preparation method thereof, belonging to the technology of solar energy utilization equipment. Background technique [0002] The solar concentrating reflector component of the present invention includes various forms of concentrating reflector components for solar heat utilization such as solar thermal power generation, heating engineering, cooking rice and boiling water, etc., especially the trough solar energy for solar thermal power generation. The thermal power concentrating mirror component, the tower type solar thermal power concentrating mirror component and the dish solar thermal power concentrating mirror component are the key points of the solar concentrating mirror component of the present invention. [0003] The mirror surface of the trough solar thermal power concentrating mirror is generally a parabola or a combination of parabola and involute structure, while the mi...
