Description

A kind of damp-proof PVC co-extrusion foaming board

Technical field

This utility model relates to field of material technology, particularly relates to a kind of damp-proof PVC co-extrusion foaming board.

Background technology

PVC foam plate is also called PVC expansion sheet and An Di plate, and its chemical composition is polrvinyl chloride, so also referred to as foam gathers Vinyl chloride sheet.It is widely used in passenger vehicle, railway carriage ceiling, casing sandwich layer, interior decoration plate, skin plate, built-in Decorations with plate, office, house, public place building compartment, commercial decorative frame, used in dustless room plate, ceiling board, screen printing, Computer lettering, advertisement sign, panel, the mark industries such as plate photograph album plate and chemical anticorrosion engineering, thermoforming part, freezer use Plate, special prepressing reserving works, environmental protection template die, sports equipment, cultivation material, beach protection against the tide facility, water-resistant material, art designing's material and Various light dividing plates replace glass ceiling etc..The most waterproof, fire-retardant, acid and alkali-resistance, mothproof, light weight, insulation, sound insulation, the characteristic of damping； 2. process on an equal basis with timber, and processing characteristics is far superior to timber；3. it is the ideal substitute of timber, aluminium, composite board；4. Skinning plate surface unusual light, hardness is high, it is not easy to have cut, is usually used in making cabinet, furniture etc..

Current foamed board replaces various planks conventional in existing structure, thus plays minimizing trees felling, protects The purpose in retaining ring border, but PVC foam plate, do not possess fire resistance, runs into wet environment changeableness, has service life to limit, It is difficult to meet the demand of people.

Compared with prior art, the beneficial effects of the utility model are: this utility model simple in construction, reasonable in design, This utility model is anti-by arranging the first waterproof layer, the first flame retarding material, drying layer, the second flame retarding material and second Water material layer, such PVC foam plate the first waterproof layer, the first flame retarding material, drying layer, the second flame retarding material with Having the most fire-retardant, good waterproof performance under the effect of the second waterproof layer, be adapted to high intensity environment and use, performance is steady Fixed, indeformable, high temperature resistant.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Detailed description of the invention

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing and enforcement Example, is further elaborated to this utility model.Should be appreciated that specific embodiment described herein is only in order to explain This utility model, is not used to limit this utility model.

Referring to Fig. 1, Fig. 1 is structural representation of the present utility model.

A kind of damp-proof PVC co-extrusion foaming board, including first PVC foam layer the 1, second PVC foam layer 7, a described PVC Foaming layer the 1, second PVC foam layer 7 thickness is identical, sets gradually between described first PVC foam layer the 1, second PVC foam layer 7 There are first waterproof layer the 2, first flame retarding material 3, drying layer the 4, second flame retarding material 5 and the second waterproof layer 6, institute The thickness stating first waterproof layer the 2, second waterproof layer 6 is identical, described first flame retarding material the 3, second fire proofing The material thickness of layer 5 is 1mm～5mm.

Described first flame retarding material the 3, second flame retarding material 5 is aluminium hydroxide or magnesium hydroxide or glass fibre, institute State first waterproof layer the 2, first waterproof layer 6 and for polyurethane or neoprene or butyl rubber or polrvinyl chloride or gather different Butylene, and the material of described drying layer 4 is calcium sulfate or calcium chloride.So PVC foam plate is at the first waterproof layer 2, first Have the most fire-retardant, anti-under the effect of flame retarding material 3, drying layer the 4, second flame retarding material 5 and the second waterproof layer 6 Aqueous is good, is adapted to high intensity environment and uses, and stable performance is indeformable, high temperature resistant.

In description of the present utility model, unless otherwise clearly defined and limited, term " install ", " being connected ", " even Connect ", " fixing " should be interpreted broadly, connect for example, it may be fixing, it is also possible to be to removably connect, or integral；Permissible It is to be mechanically connected, it is also possible to be electrical connection；Can be to be joined directly together, it is also possible to be indirectly connected to by intermediary, can be two The connection of individual element internal or the interaction relationship of two elements.For the ordinary skill in the art, can have Body situation understands above-mentioned term concrete meaning in this utility model.
