Abstract

The utility model belongs to a door with special purposes, which is used for buildings and devices of cold storage, hothouses, re-drying devices of a tobacco machine, a transportation and refrigeration vehicle, etc. The door with special purposes is composed of glass fiber reinforced plastics and polyamine ester foam plastic which are adhered by resin. The utility model has the advantages of light weight, good heat-insulating property, corrosion resistance, high strength, etc.

Description

Thermal insulating door

The utility model belongs to the door of specific use, is used for building and equipment such as freezer, greenhouse, the redrying of cigarette machine, transport refrigeration railway carriage.

The thermal insulation door of traditional steel work is with iron sheet heat insulating materials such as rock wool, glass wool to be housed as enclosure, and the weight of this door is big, heat-insulating property is bad, and inconvenience is installed and since shell use iron plate not corrosion-resistant easy corrode.

In order to overcome the shortcoming of original technology, to be a kind of use glass fiber reinforced plastic polyamine fat plastic foam of design make the complex heat-preservation door-plate as material to the purpose of this utility model according to the specification shape hinge, keeper is given when the making sheet and burying, thereby make in light weight, the good heat insulating appearance looks elegant, the thermal insulation door new product corrosion-resistant, that intensity is high.

The utility model is realized by following measure:

A kind of thermal insulation door is to be made of shell, inner core, it is characterized in that shell is to make surperficial gel coating resin viscosity number layer glass fabric with flexible resin, and inner core is to fill polyurethane foamed plastic to combine, and the endosexine is by connecing cloth with the bonding glass of heat stable resin or the felt weak point is cut yarn fabric; Keeper, hinge are made and are given embedded part.

Thermal insulation door is to make on the mould of preparation according to shape, specification, size, brush release agent earlier, be coated with surperficial gel coating resin, in order to guarantee the door-plate appearance looks elegant, gel coating resin adopts flexible resin, repave polyurethane foamed plastic, add to give by design attitude and bury keeper, hinge member, shop glass fabric, undercoat felt fabric are coated with heat stable resin, then matched moulds, curing, the demoulding under the room temperature again cut edge and made product.

The utility model is realized by following measure:

Thermal insulation door is to make on the mould of preparation according to shape, specification, size, the brush release agent is coated with surperficial gel coating resin, in order to guarantee the door-plate appearance looks elegant earlier, gel coating resin adopts flexible resin, repave polyurethane foamed plastic, add to give by design attitude and bury keeper, hinge member, shop glass fabric, undercoat felt fabric, be coated with heat stable resin, matched moulds then solidifies under the room temperature, the demoulding again, cuts edge and makes product.

Advantage of the present utility model:

1) owing to adopt glass fiber reinforced plastic, polyamine fat plastics to make thermal insulation door, has its weight in light weight 1/4 of Steel structure door is only arranged.

2) because the coefficient of thermal conductivity of polyurethane foamed plastic has only 1/5 of traditional material, so good heat insulating.

3) weak point is cut felt or the fabric inner core is made cellular and polyurethane foamed plastic owing to adding in making, so increased intensity, rigidity and raising heat-insulating property greatly.

4) corrosion-resistant, ageing-resistant.

5) freezer equipment in transportation adopts this door can absorb vibrational energy, has the effect of vibration damping, noise elimination.

6) thermal insulation door finish height is aesthetic in appearance.

ě 7) can make the door of shape such as rectangle, circle, elliptical plate or deflection shape, arch and specification according to the requirement of equipment.

Accompanying drawings is as follows:

Accompanying drawing 1: plain batton door sectional drawing; Accompanying drawing 2: plain batton door;

Accompanying drawing 3: arched door sectional drawing; Accompanying drawing 4: arched door;

Accompanying drawing 5: round door sectional drawing; Accompanying drawing 6: round door.

See Fig. 1,2,3,4,5,6, be coated on the mould surface glue coating resin or flexible resin (1) bonding with the water saturation polyamino resin, several layers of glass fabric (2), shop polyurethane foamed plastic and cellular thing (3) are installed prefabricated component (5), are coated with heat stable resin shop glass fabric, short felt or the fabric (4) cut.

Claims

1, a kind of thermal insulation door, constitute by shell, inner core, it is characterized in that shell is to make surface course with gel coating resin or flexible resin, use unsaturated polyester resin viscosity number layer glass fabric again, inner core is to fill polyurethane foamed plastic or cellular thing and polyamine fat vacuole foam to combine, and the endosexine is heat stable resin adhering glass cloth or the short felt yarn fabric of cutting.

2, thermal insulation door according to claim 1 is characterized in that keeper, hinge member are hidden in advance between inner core and endosexine.

3, thermal insulation door according to claim 1 is characterized in that using different moulds to make the door of shapes such as circle, rectangle, ellipse, plane or arch.
