Abstract

The utility model relates to hollow glass with a heat-insulating membrane and double cavities, comprising two glass plates and a plurality of sectional material frames, wherein drying agents are filled in the sectional material frames. The hollow glass with a heat-insulating membrane and double cavities is characterized in that a heat-insulating membrane is disposed between the two glass plates, a plurality of sectional material frames are disposed between the glass and the heat-insulating membrane, and two cavities fully filled with dry air are formed at the middles of the two pieces of glass; and an polyisobutene adhesive is coated at the connected places of the sectional material frames and the glass plates and at the connected places of the sectional material frames and the heat-insulating membrane. The hollow glass with a heat-insulating membrane and double cavities disclosed by the utility model has the advantage that the lower heat transmissivity is, the better energy-saving effect is.

Description

Thermal isolation film two-chamber double glazing

Technical field

The utility model relates to a kind of double glazing, especially relates to a kind of thermal isolation film two-chamber double glazing.

Background technology

At present, known double glazing is in the middle of two glass sheets, the section material framework of folder to combine; The siccative of filling some amount in the section bar is after secondary seal, pressing, curing, in the middle of two glass sheets; Constitute a cavity that is full of dry air, thereby process double glazing.In temperature outside is 0 ℃; The inboard is 20 ℃; Outside wind speed 0.38m/sec; Inboard wind speed is under the 0m/sec condition, and by common single chamber double glazing that 12 ㎜ section material frameworks and two 3 ㎜ float glass process white transparent glasses are formed, its hot transmitance is 2.74kcal/ (m ²H ℃).

Summary of the invention

To the problems referred to above, the purpose of the utility model is to provide the thermal isolation film two-chamber that a kind of hot transmitance is low more, energy-saving effect is higher double glazing.

The technology contents of the utility model does; A kind of thermal isolation film two-chamber double glazing; It comprises two glass sheets and some section material frameworks, is filled with siccative in the section material framework, it is characterized in that between two glass sheets, being provided with a thermal isolation film; Between glass and thermal isolation film, be provided with some section material frameworks, have two cavitys that are full of dry air at two sheet glass intermediate formation; Scribble polyisobutylene adhesives with sheet glass, thermal isolation film connecting place respectively at section material framework.

Polyisobutylene adhesives and thermal isolation film are conventional products in above-mentioned utility model.

The preparation process of thermal isolation film two-chamber double glazing is following in the utility model:

(1), pastes polyisobutylene adhesives at the two ends of filling siccative section material framework;

(2), two ends are scribbled the corresponding in twos both sides that are bonded in the effectively insulating film of section material framework of polyisobutylene adhesives;

(3), be put into the effectively insulating film that has section material framework that makes in the step (2) in the middle of two glass sheets, and make section material framework and bonding glass through polyisobutylene adhesives; After secondary seal, pressing, curing, process finished thermal insulation film two-chamber double glazing.

The utility model utilizes polyisobutylene adhesives to be bonding medium, is bonded in the effectively insulating film in the middle of the section material framework of two groups of filling siccative; Utilize polyisobutylene adhesives to have combination the section material framework of effectively insulating film to be combined in the middle of two sheet glass; Utilization is clipped in the effectively insulating film of sheet glass middle device and the width of section material framework, in the middle of two sheet glass, produces to have two cavitys that are full of dry air; After secondary seal, pressing, curing, thereby process a kind of effectively insulating film two-chamber double glazing.In temperature outside is 0 ℃; The inboard is 20 ℃; Outside wind speed 0.38m/sec; Inboard wind speed is under the 0m/sec condition, and by the effectively insulating film two-chamber double glazing that 12 ㎜ section material frameworks and two 3 ㎜ float glass process white transparent glasses and one deck 0.2 ㎜ effectively insulating film are formed, its hot transmitance is 1.12kcal/ (m ²H ℃).Heat-energy losses descends 41% than common single chamber double glazing.
