Abstract
The utility model relates to a composite safety glass writing board, which is composed of a glass panel 1, a glass fiber reinforced plastic composite layer 2, a closed-cell foamed buffer layer 3 and a back board (a reinforcing layer) 4. Because of the compact combination between the glass panel and the glass fiber reinforced plastic composite layer, the protection of the closed-cell foamed buffer layer, and the reinforcement of the back board, the strength of the composite safety glass writing board can be greatly increased and the writing board is difficult to be damaged, and even the writing board is broken, glass fragments can be stuck to the glass fiber reinforced plastic composite layer without falling off to hurt people. The front face of the glass panel is a writing face with high hardness, and the writing board is available for writing of watercolor or greasepaint, which is easy for writing as well as erasing with never-discolored, non-cracking, scratch free and accumulated-ink resistant advantages. The composite safety glass writing board is weatherable and can be used at any locations indoors and outdoors.
Description
Technical field:
The utility model relates to a kind of clipboard, belongs to clipboard manufacturing technology field, particularly the technical field of the combined type safety glass clipboard of writing with watercolor or greasepaint.
Background technology:
Present common use glass writing board use glued board, fiberboard or resin plate to make backboard.In case, be easy to fragmentation and glass disintegrating slag and fall down life safety is constituted a threat to because these plates are difficult for being clashed into the closely connected glass of glass plate.State Intellectual Property Office disclosed " light-duty safety glass clipboard " on November 8th, 2000, it disclosed a kind of can absorb effectively to the impact of glass plate and vibrations glass plate broken and do not fall slag, remove that chalk dust is convenient, row's plate easily, long, lightweight clipboard of plate face life-span.Plate body is made of single face frosted glass plate, dark color (black, mass colour or blackish green) posting in time, backboard; Posting in time is bonded at the shiny surface of single face ground glass plate, have absorption to the impact of glass plate, shake and prevent that the glass plate fragmentation from falling the effect of quarrel; The shortcoming of " light-duty safety glass clipboard " is that the ground glass face is a writing surface, can only dip in clear water with chalk or writing brush and write, and just writes with watercolor or greasepaint and wipes not fall.And this patent with posting in time connect the shiny surface of ground glass plate when bonding basic row do not go out the air of bonding plane, behind the air expanded by heating, thereby lose bonding effect.Backboard KT plate shock resistance effect is limited, is difficult to accomplish to absorb effectively to the impact of glass plate and vibrations glass plate broken and do not fall slag, and the durability that posting in time connects also can not get ensureing, let alone safe and reliable.
The utility model content:
It is writing surface that the purpose of this utility model is to disclose the smooth front of a kind of glass-board surface, the combined type safety glass clipboard of writing with watercolor or greasepaint.Be mainly used in and replace present widely used iron sheet blank.After iron sheet blank major defect is to use a period of time, owing to write rubbing action with wiping, make the long-pending China ink of the injured formation of writing surface of hardness deficiency and card.
The technical solution of the utility model is:
A kind of combined type safety glass clipboard of writing with watercolor or greasepaint, by glass-board surface, the fiberglass composite bed, closed-cell foam cushion and backboard enhancement Layer constitute, it is characterized in that: glass-board surface thickness is 3～8 millimeters, the front that the plate face is smooth is a writing surface, the back side is the frosted layer, alternately cover 1～3 layer at the glass-board surface back side with epoxy resin after painted and glass layer, behind the epoxy resin cure, epoxy resin, glass fibre forms the fiberglass composite bed of combining closely with glass-board surface frosted layer, be that 10～20 millimeters closed-cell foam cushion sticks on the fiberglass composite bed back side with thickness again, backboard enhancement Layer available thickness is that 3～6 millimeters laminate or particle board is bonded in the foam back, and each layer after bonding adds upholstery border all around.
The utility model compared with prior art, because glass-board surface and fiberglass composite bed are combined closely, add the protective effect of closed-cell foam cushion and the booster action of backboard again, make the utility model combined type safety glass clipboard intensity increase substantially, be not easy to damage very much; Even damage, glass fragment also will be bonded on the fiberglass composite bed, can not come off and hurt sb.'s feelings.Because the shiny surface of glass-board surface is writing surface hardness height, and is will never change colour, do not ftracture, easy-to-write and erasable does not stay cut, never long-pending China ink.Be not afraid of and expose to the sun and rain, can be used for any place of indoor and outdoor.
