Description
Technical field
The present invention relates to a kind of heat insulating decorative boards and its production technology with mounting connection structure.
Background technology
Expanded polystyrene (EPS)（EPS）With density is low, specific strength is high, water absorption rate is low, acid and alkali-resistance, sound deadener/insulator are good, protect
Warm nature is good, and shockproof, the advantages that can decorating, is easily molded and excellent cost performance are grown rapidly it, except in buffers packet
Outside dress, food fresh keeping packaging, inside and outside wall thermal insulation, heat-insulated etc. are widely applied, also in building, industrial circle more and more in recent years
Seem and attract people's attention.EPS is its heat preservation, heat-proof quality, its a large amount of use in building in the contribution that Application in Building protrudes
Use and the heating energy consumption of air-conditioning can be effectively reduced, and reduces the discharge of carbon dioxide.EPS is only single use at present
In every field, with the change of environment, simple EPS foam heat-insulating boards have occurred easy to crack, easy to fall off and unsightly
The problem of, new thermal insulation material is needed to replace EPS thermal insulation materials.Wood-plastic material, due to its have very high fire line, can
Plasticity and sound-proofing, have both high-environmental, nuisanceless, pollution-free, recyclable, and alternative color and material it is more and
Favored by more and more people.It is substantially stable for the moulding process of insulating plastic pipe at present, but in process of production
There are still the problem of some costs are excessively high, condition is harsh, bonding is insecure etc..
If when carrying out flame retardant treatment to finished product glued board, the adhesive for being generally employed to produce glued board is phenolic resin
Or cyanurotriamide modified urea resin, and gluing oxidant layer has larger impact to the scattering and permeating of fire retardant.If face ply
When remaining more fire retardant, product easily generates moisture absorption and returns white phenomenon, and subsequent secondary operation can and paint poor performance, if
Only to plywood skin veneer flame retardant treatment, expected flame retardant effect is often not achieved, needs to increase aid in treatment or increase to answer
Qualifications.
After organic insulation material reaches relevant criterion requirement or increases certain ancillary method, more it should be emphasized that the entirety of system
Fire savety.The evaluation of thermal insulation material fire-protection rating cannot represent system whole fire safety performance or fire occur when
Real conditions, even if the material of certain fire retardant grades is when condition has can vigorous combustion, so we should catch external thermal insulation
The emphasis of fire safety problem.The Reaction to fire of only outer heat preservation system entirety is functional, and the make of system is reasonable, Cai Nengbao
The fire safety performance of card architectural exterior insulation system is met the requirements, and just has extensive practical significance to engineer application.
