Abstract
The present invention relates to the preparation method that composite board installed by a kind of Novel marine freezer, by composite board measure up-protective layer and lower substrate layer; Expandability phenol-formaldehyde resin modified, surfactant, blowing agent, curing agent and auxiliary agent are sprayed between up-protective layer and lower substrate layer by High Pressure Gun head after 25 DEG C-60 DEG C heating mixing, carry out namely obtaining composite board after emulsification, sizing insulation 24 hours, the demoulding through continuous production line equipment; Described expandability phenol-formaldehyde resin modified: surfactant: blowing agent: curing agent: the mass ratio of auxiliary agent is 100:4:5:25:5; Described surface-active agent is silane and the universal surfactant of TWEEN Series; Described blowing agent is NACO or metal dust general solid blowing agent; Described curing agent is hydrochloric acid or sulfuric acid or phosphoric acid; Described auxiliary agent is boric acid or urea or antimony oxide.
Description
Technical field
The present invention relates to a kind of composite insulating board, especially relate to a kind of preparation method being applicable to the metal face type phenolic aldehyde composite insulating board of the warming plates such as shipbuilding industry freezer.
Background technology
Cold storage plate is as the requisite important component part of freezer in messes refrigeration in Modern Shipbuilding industry, and its material and manufacture craft are along with the continuous progress of science and technology is also in continuous renewal.As: the heat-barrier material of traditional bulk type freezer is rock wool or super glass wool, in processing and installation process, all can produce harmful dust, harmful, heat insulation effect relative mistake, and adds hull weight.Assembly cold storage polyurethane composite module sheet material Assembling, simple and fast during installation, mounting process is simple, saved the plenty of time, and tailored appearance is smooth, has beautified cabin.But because sheet material is by polyurethane foam as insulation material, this material thermal resistance is poor, easy firing, calory burning is large and produce poison gas, easily causes the injures and deaths of trapped personnel and rescue personnel; Simultaneously heat insulation foamed material structure intensity difference, single when using as cold storage plate, freezer overall construction intensity is poor, and usage safety performance is low.
Summary of the invention
For the deficiency that in present shipbuilding, freezer sheet material fire-protection rating is inadequate, structural strength is poor, usage safety performance is low, the invention provides that a kind of structure is simple, preparation technology is simple, structural strength is high, the Novel marine freezer of use safety installs composite board and preparation method thereof.
To achieve these goals, the technical solution used in the present invention is: the preparation method of composite board installed by a kind of Novel marine freezer, by composite board measure up-protective layer and lower substrate layer; Expandability phenol-formaldehyde resin modified, surfactant, blowing agent, curing agent and auxiliary agent are sprayed between up-protective layer and lower substrate layer by High Pressure Gun head after 25 DEG C-60 DEG C heating mixing, carry out namely obtaining composite board after emulsification, sizing insulation 24 hours, the demoulding through continuous production line equipment; Described expandability phenol-formaldehyde resin modified: surfactant: blowing agent: curing agent: the mass ratio of auxiliary agent is 100:4:5:25:5; Described surface-active agent is silane and the universal surfactant of TWEEN Series; Described blowing agent is NACO or metal dust general solid blowing agent; Described curing agent is hydrochloric acid or sulfuric acid or phosphoric acid; Described auxiliary agent is boric acid or urea or antimony oxide.
Compared with prior art, advantage of the present invention is: moderate soak layer adopts phenolic foam foaming, makees blowing agent without freon, the gas that burning is overflowed is nontoxic, thermal conductivity factor 0.024w/m.k, water absorption rate <0.2%, insulation effect is good, is conducive to freezer rule and improves and save energy and reduce the cost; The up-protective layer of foaming up and down of moderate soak layer and lower substrate layer, overall construction intensity is high, model calling; good airproof performance, without condensation water, fire prevention, sound insulation, overall shock-resistant, collision; not cracky, anticorrosive and ageing resistance good, use safety, life-span are long.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: up-protective layer 1, moderate soak layer 2, lower substrate layer 3.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
Shown in Fig. 1; a kind of Novel marine freezer is installed composite board and is comprised up-protective layer 1, moderate soak layer 2 and lower substrate layer 3; up-protective layer 1, moderate soak layer 2 and lower substrate layer 3 from top to bottom superpose successively; moderate soak layer 2 is phenol-formaldehyde resin modified insulating foam layer; moderate soak layer thickness is 20 ~ 150mm; up-protective layer 1 is galvanized steel plain sheet or stainless steel or color steel; up-protective layer thickness is 0.1 ~ 0.5mm; lower substrate layer 3 is galvanized steel plain sheet or stainless steel or color steel or aluminium sheet protection surface layer, and lower substrate layer thickness is 0.05 ~ 0.5mm.
The preparation method that composite board installed by Novel marine freezer of the present invention is: by composite board measure up-protective layer and lower substrate layer; Expandability phenol-formaldehyde resin modified, surfactant, blowing agent, curing agent and auxiliary agent are sprayed between up-protective layer and lower substrate layer by High Pressure Gun head after 25 DEG C-60 DEG C heating mixing, carry out namely obtaining composite board after emulsification, sizing insulation 24 hours, the demoulding through continuous production line equipment; Described expandability phenol-formaldehyde resin modified: surfactant: blowing agent: curing agent: the mass ratio of auxiliary agent is 100:4:5:25:5; Described surface-active agent is silane and the universal surfactant of TWEEN Series; Described blowing agent is NACO or metal dust general solid blowing agent; Described curing agent is hydrochloric acid or sulfuric acid or phosphoric acid; Described auxiliary agent is boric acid or urea or antimony oxide.
Embodiment recited above is only be described the preferred embodiment of the present invention; not design of the present invention and protection are limited; under the prerequisite not departing from design concept of the present invention; the various modification that in this area, common engineers and technicians make technical scheme of the present invention and improvement, all should fall into protection scope of the present invention.
