preparation example Construction

[0014] A preparation process for post-filling energy-saving and heat-preserving door and window profiles. The solution is to seal the two ends of the profile 5, and process the pouring hole 1 on one end of the side of the door and window 6 profile 5 and the vent hole 4 on the other end, or directly Install and fix the mold with the check valve 2 with the opened hole on the two end faces of the profile 5. The end face where the check valve 2 is installed is the end of the filling hole 1 and the other end is the end of the exhaust hole 4. The filling hole 1 is installed There is a check valve 2, a 100-mesh stainless steel filter screen 3 is installed on the exhaust hole 4, and a sealing strip is pasted around the filter screen 3. The end of the door and window profile 5 where the perfusion hole 1 is processed is inserted through with a filling gun Check valve 2, the filling gun is equipped with energy-saving thermal insulation foaming material, turn on the filling gun switch, fill...

Embodiment 1

[0016] Example 1: In actual use, first process a hole at both ends of the profile 5 to be produced, and install a sealed check valve 2 on one hole 1 to ensure that the check valve 2 does not leak or leak. The filter screen 3 is installed on the other end hole 4, and the filter screen is pasted and fixed on the profile hole with a sealing strip, and the gun head is installed with the air tube, adapter, needle and sealing gasket. Check valve 2, (or directly install the mold with the check valve 2 in the opened hole and fix it on the two end faces of the profile 5. The end face where the check valve 2 is installed is the end of the filling hole 1. Install the trachea, Adapter, needle, and gasket The improved filling gun needle is inserted through the check valve 2, the other end is the vent 4 end, and the filter 3 is installed on the other end of the vent 4 end, with a sealing strip Paste and fix the filter screen on the profile hole.) Install a suitable one-component polyurethane...

Abstract

The invention discloses a preparation process of post-filling energy-saving and heat-preserving door and window profiles. Back valve, 100-mesh stainless steel filter screen is installed on the exhaust hole, and a sealing strip is pasted around the filter screen. The filling gun is inserted through the check valve at the end of the door and window profile processed with the filling hole, and the filling gun is equipped with Foaming material, turn on the switch of the filling gun, fill the foaming material into the pouring hole, observe the foaming material at the vent hole, when it is observed that the foaming material is 2-4mm away from the vent hole, close the filling gun to stop filling Inject foaming material, seal the vent hole with a sealing strip, leave it for 24 hours to foam and solidify, tear off the sealing strip on the vent hole, and the finished profile is obtained. The present invention is not limited by the size of the profiles for making doors and windows, has strong foaming stability, and is suitable for popularization and use in making various energy-saving and heat-preserving doors and windows.

Description

Technical field [0001] The invention relates to the technical field of building material door and window profiles, and in particular belongs to a preparation process of post-filling energy-saving and heat-insulating door and window profiles, which are used to make door and window frames and fan profiles. Background technique [0002] At present, when the construction industry makes and install doors and windows, most of the door and window profiles are aluminum alloy, stainless steel, plastic steel, etc. In actual use, these materials have good strength and strong mechanical processing performance, but they all have poor thermal insulation performance and poor overall energy saving effect. Shortcomings. In order to solve this problem, the current domestic door and window profile manufacturers adopt embedded thermal break bridge structure and cast-type broken bridge structure. The former has the disadvantages of high cost, complex technology, high processing accuracy, and easy dis...
