Abstract
The present invention relates to a kind of environmental and durable glass writing board of writing with watercolor or greasepaint, constitute by float glass plate face 1, adhesive-layer 2, glass fabric or other cloth 3, closed-cell foam cushion 4, backboard enhancement Layer 5 and upholstery border 6.Glass and glass fabric are bonded as one fully, and with the closed-cell foam buffering, impact resistance strengthens greatly again, is difficult for broken; Even damage, glass disintegrating slag and glass fibre strong bond can not come off and hurt sb.'s feelings.In light weight, durable, write smoothly, wiping is light, never long-pending China ink, card not are not afraid of and are exposed to the sun and rain, and can be used for any place of indoor and outdoor.
Description
Technical field:
The present invention relates to a kind of utmost point of writing, belong to clipboard manufacturing technology field, particularly the technical field of the environmental and durable glass writing board of writing with watercolor or greasepaint.
Background technology:
Now the case hardness of the common iron sheet blank that generally uses is not high, and at most through the writing and wiping of 3 years left and right sides time, originally smooth surface can be injured and become coarse, and ink enters coarse surface, can deposit and card gradually.
Though safety glass clipboard case hardness is consistent with this product, because the glass tempering of big panel, the thickness of glass can not be less than 8mm.Therefore there are four shortcomings in it: the one, and font has ghost image, influences vision; The 2nd, too heavy, potential safety hazard is arranged; The 3rd, itself will be out of shape behind the glass tempering, influences attractive in appearance; The 4th, after safety glass damaged, the glass disintegrating slag still can land hurted sb.'s feelings.
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 objective of the invention is to disclose a kind of glass is writing surface, the environmental and durable glass writing board of writing with watercolor or greasepaint.
Technical scheme of the present invention is:
A kind of environmental and durable glass writing board of writing with watercolor or greasepaint, by the float glass plate face, glass fabric or other cloth, adhesive-layer, closed-cell foam cushion and backboard enhancement Layer constitute, the float glass plate face thickness is the 4-8 millimeter, the one side of plate face is a writing surface, another side sprays paint and glass fabric or other cloth is glued on the paint face after painted, be that 10～20 millimeters closed-cell foam cushion is glued on glass fabric or other cloth with thickness again, backboard enhancement Layer available thickness is that the laminate or the particle board of 1-5 millimeter is bonded in the closed-cell foam back, and each layer after bonding adds upholstery border all around.
The present invention compared with prior art has following advantage:
1, write well, durable.Write smoothly, wiping is light, never long-pending China ink, card not.
2, safety.Glass and glass fabric are bonded as one fully, and with the closed-cell foam buffering, impact resistance strengthens greatly again, is difficult for broken; Even damage, the glass disintegrating slag can not come off and hurt sb.'s feelings.
3, in light weight.Weight is 50% of safety glass.Blackboard is heavy more, and potential safety hazard is also big more.And safety glass damages back glass disintegrating slag and also can come off, hurt sb.'s feelings.

Embodiments of the invention:
Embodiment:
As shown in Figure 1: a kind of environmental and durable glass writing board of writing with watercolor or greasepaint is made of float glass plate face 1, adhesive-layer 2, glass fabric or other cloth 3, closed-cell foam cushion 4, backboard enhancement Layer 5 and upholstery border 6.The float glass plate face thickness is 4 millimeters, the one side of plate face is a writing surface, another side sprays paint and glass fabric is glued on the paint face after painted, the closed-cell foam cushion that with thickness is 15 millimeters again is glued on glass fabric, backboard enhancement Layer thickness is that 5 millimeters laminate is bonded in the closed-cell foam back, and each layer after bonding adds that upholstery border forms complete blackboard all around.
