Technical field
This utility model belongs to composite board manufacturing technology field, particularly relates to a kind of phenolic foam sandwich flame-retardant composite board and manufacturing technology.
Background technology
Phenolic foam sandwich flame-retardant composite board is as upper and lower plane materiel by flame retardant fibre board, with hard phenol formaldehyde foam for core, by the sandwich composite board that one-shot forming or secondary forming process (hot pressing or mode of colding pressing) are prepared from, also known as light-duty flame retardant fibre board sandwich hard phenolic foam composite plate.General density is less than or equal to 350kg/m3Sandwich composite board.
Interior/exterior decoration finishing material is the key factor determining building trade safety, and the generation of a large amount of fire incidents all shows, mainly uses combustible material to cause.Flame retardant fibre board is a kind of artificial wood-based board, there is the features such as fire-retardant and easy secondary operations use, it is widely used in the furniture of public place, floor and door-plate manufacture and indoor decorating field, but the defect such as self there is matter weight, thickness is little and thermal and insulating performance is poor, use scope is subject to a definite limitation.Wang Zhicai, Bai Peikang scholar points out at " research of phenol formaldehyde foam and composite thereof and application " literary composition, phenol formaldehyde foam is a kind of lightweight, fire-retardant, insulation and heat insulation expanded plastic material, there is fire-retardant, low-smoke low-toxicity and the heat stability of excellence, but have that intensity is low, surface quality is poor, easy dry linting and the defect such as fragility is big.
Currently, along with the development of material manufacturing technology, sandwich sandwich is increasingly used widely.Hong Lu, Wang Meilan etc. " prediction of phenolic foam material industry development " the article pointed out, phenolic foam board is many with phenolic foam for central layer, and surface pastes aluminium sheet, color steel or non-woven fabrics.And at present flame retardant fibre board pastes phenolic foam products and still belongs to lab scale conceptual phase in market, industrialization is had not yet been formed.How to overcome flame retardant fibre board and the self-defect of phenolic foam board own, the advantage playing each material, solve that flame-retarded light composite production efficiency is low or difficulty realizes the drawback of automated production, thus widening fire-retardant composite wood in applications such as industry and civil buildings warming plate, internal partition wall, roofing, ceilings, meet market place differentiation demand, to promoting the development of wood-based plate transition and upgrade, eliminate disaster hidden-trouble, ensure safety, significant.For solving above-mentioned technical bottleneck, research utility model phenolic foam sandwich flame-retardant composite board and industrialization produce significant.
Utility model content
The purpose of this utility model is in that for the deficiencies in the prior art, it is provided that a kind of phenolic foam sandwich flame-retardant composite board, widens it as field ranges of application such as non-structural building decoration, warming plate, partition wall, roofing, variolas, eliminates disaster hidden-trouble, it is ensured that safety.
The purpose of this utility model is achieved through the following technical solutions.
A kind of phenolic foam sandwich flame-retardant composite board, including upper layer, cutting optimal and sandwich layer, it is characterized in that, using flame retardant fibre board as upper layer, cutting optimal, with hard phenol formaldehyde foam for sandwich layer, between flame retardant fibre board upper layer and hard phenol formaldehyde foam sandwich layer and between flame retardant fibre board cutting optimal and hard phenol formaldehyde foam sandwich layer, contain phenolic resin glue or amino resin adhesive layer；The thickness of described flame retardant fibre board upper layer is 1.0-45.0mm, and the thickness of described flame retardant fibre board cutting optimal is 1.0-45.0mm, and the thickness of described hard phenol formaldehyde foam sandwich layer is 10.0-450.0mm.
The glue-spread of described phenolic resin glue or amino resin adhesive layer is 100kg-150kg/m2。
The breadth of described composite plate be shaped as arbitrary shape.
Being shaped as of the breadth of described composite plate is square.
The breadth of described composite plate is arbitrary dimension.
The book size of described composite plate is 4 × 8 chis or 4 × 16 chis.
Relative to prior art, the method have the advantages that in phenolic foam sandwich flame-retardant composite board of the present utility model containing phenolic resin glue or amino resin adhesive layer.While improving its adhesion strength, give again composite material light, insulation, heat insulation and fire protecting performance.Expand the use scope of phenolic foam sandwich flame-retardant composite board, solve and be difficult to the common technology bottleneck problem such as industrialization or automated production.Contribute to promoting the further development of forest product industry, there is good Social benefit and economic benefit.
