Description
Technical field
The present invention relates to a kind of energy-saving building materials, and in particular to a kind of hollow glass rigidly warm side spacer bar and its preparation
Method.
Background technique
At present in the case where China carries forward vigorously the big situation of energy-saving and emission-reduction, building energy conservation is the most important thing.Building energy consumption is complete
30% or more of social total energy consumption.And door and window energy conservation is the most important thing of building energy conservation, it is to pass through door that building energy consumption, which has half,
Window loss.Having any in door and window energy conservation is that cannot be neglected, that is, hollow glass spaceband, hollow glass edge pass through
Spacer bar carries out heat transfer, and thermal loss is made to cause the waste of whole society's energy.Have in Chinese market at present cold side spacer bar and
Warm side spacer bar, cold side spacer bar is using aluminum strip as representative, thermal coefficient about 160W/MK, and thermal loss is very big and can make
It condenses on the inside of empty glass chamber and generates bacterium.Warm side spacer bar has stainless steel spacer bar, stainless steel and the compound spacer bar of plastics, glass
Fibre reinforced composite material pastes composite membrane spacer bar etc..Since the thermal coefficient for warming up side spacer bar is low, such as: stainless steel thermal coefficient
About 15W/MK, polypropylene thermal coefficient about 0.19W/MK, polyvinyl chloride thermal coefficient about 0.17W/MK, hollow glass side
Portion, which carries out heat transfer by warm side spacer bar, to be greatly reduced, and thermal loss greatly reduces.
Chinese architecture glass and industrial glass association have issued Chinese architecture glass and industrial glass on 2 1st, 2016
Association criterion " warm side spacer bar " HBZ/T 003-2016, implements on April 1st, 2016 in the whole nation.According to Chinese architecture
Glass and industrial glass association criterion " warm side spacer bar " HBZ/T 003-2016, heat transfer performance is evaluated with C-factor
Parameter is indicated by the weighted value of the product d. λ of the thickness and thermal coefficient of spacer material.
Warm side spacer bar needs to have following performance characteristics:
1. spacer bar of the C-factor no more than 0.007W/K is only warm side spacer bar.C-factor is by spacer material
The weighted value of the product d. λ of thickness and thermal coefficient indicates.Need to bear the weight and wind load of hollow glass due to warming up side spacer bar
Lotus, warm side spacer bar need to have certain intensity, and the thickness to material is to have certain requirements, then will try to reduce warm
The thermal coefficient of side spacer material.
2. needing filling with inert gas, such as argon gas in hollow glass chamber to obtain hollow glass low heat conductivity, in hollow glass
In glass period whole service life, inert gas cannot all be leaked.The steam outside hollow glass can not be by warming up side simultaneously
Spacer bar frame enters hollow glass chamber, to avoid hollow glass failure.This requires warm side spacer bars to have barrier gas well
The performance of body and steam.
In the production process of warm side spacer bar, have the following problems:
If 1) warm side spacer bar is made with stainless steel, due to the compactness of stainless steel material itself, gas can be obstructed
Hollow glass chamber is penetrated into steam.But since stainless steel thermal coefficient is higher, and the density of load that stainless steel is born causes
The thickness of stainless steel cannot be too thin, so the C-factor of stainless steel heating side spacer bar is closest to limiting value, and heat
Amount loss is more.Simultaneously because stainless steel own mechanical performance characteristics, roll in continuous bending in corner often
The problems such as disconnected, breakage and gauffer.If the sawed-off use plastics limb of stainless steel spacer bar is connected, can be leaked in junction
Gas drainage.
If 2), can be continuous at normal temperature with full-automatic or half-automatic folding bender with stainless steel and the compound spacer bar of plastics
Bending, and be not in gas leakage drainage in corner.Due to the compactness of stainless steel material itself, it is of course possible to obstruct
Gas leak and steam penetrate into hollow glass chamber.But since stainless steel thermal coefficient is higher, for certain thickness stainless steel
Piece C-factor is also higher, is also certainly relatively more by the heat that this part stainless steel substrates loses.Simultaneously not
The production technology and equipment of rust steel and the compound spacer bar of plastics are all more complicated, higher cost.
If 3) composite membrane spacer bar is pasted with glass fibre reinforced composite material, due to the barrier gas and steam of composite membrane itself
Performance, it is of course possible to obstruct hollow glass intracavity gas leak and external moisture penetrate into hollow glass chamber.But fiberglass reinforced
The elongation percentage of composite material at normal temperature is lower, poor toughness, full-automatic or half-automatic folding bender cannot be used continuous at normal temperature
Bending.Use bending or warm side interval strap saw again after the full-automatic or half-automatic folding bender heating with heating device
It has no progeny and is connected using plastics limb.The warm side spacer bar frame that both modes make is existing in corner's leak that can all leak air
As.Because heating before warm side spacer bar bending in corner, glass fibre reinforced composite material temperature distortion can be made, lead to warm side interval
Corner's dimension overproof, while heating warm side spacer bar and can also reduce production efficiency.If warm side spacer bar it is sawed-off after make
It is connected, then can leaked air drainage in junction with plastics limb.Glass fibre reinforced composite material pastes composite membrane interval simultaneously
The production technology and equipment of item are all more complicated, higher cost.
Polyketone is a kind of novel high polymer crystalline material just to have emerged, has high barrier, high self-lubrication, high rigidity
And high impact resistance, high heat distortion temperature, short molding cycle, excellent high resiliency and have polypropylene PP possessed by hundred foldings
The characteristic of glue.But how polyketone is used as glass and warms up side spacer bar, make full use of the characteristic of polyketone, to make the warm side interval of rigidity
Item is with excellent watertightness and air-tightness, low thermal conductivity, high rigidity and excellent high resiliency and has clod wash characteristic,
There is presently no relevant document explanations.
