Problems solved by technology

[0006] However, there are three major problems in doors and windows using broken bridge aluminum alloy profiles: one is that the cross-sectional area of ​​aluminum alloy door and window profiles increases, which increases the consumption of aluminum alloys (the weight ratio of broken bridge aluminum alloy profiles to non-broken bridge aluminum alloy profiles is 10.5: 6.5), increasing the production cost of doors and windows; second, the non-metallic materials used in the middle of the two aluminum materials, most of which are plastics, will age after a long time, affecting the strength and safety of doors and windows; Secondary pollution of the environment
The coating process of this method is relatively complicated, and it is necessary to coat the coating containing glass beads first, because the glass beads will be broken a lot during the mixing process with other components of the coating, so it is necessary to coat the glass beads separately coating, followed by a coating containing glass beads
[0008] Since the glass bead coating applied separately is post-added, the fusion is not good enough and delamination will occur, so the thermal insulation performance will also be affected

preparation example Construction

[0082] The present invention also provides a method for preparing the above-mentioned coating, which comprises the steps of: a. after the film-forming agent is broken, it is mixed with a curing agent, a foaming agent and a leveling agent; b. the mixed raw materials are kneaded with an extruder Then, discharging, tableting, and cooling to room temperature; c. The tableting raw materials are sent to the crushing and screening unit, crushed, classified and sieved, and the particle size is 170-220 mesh to obtain the desired powder coating.

[0083] Wherein, before step a, the foaming agent may be ball-milled and then passed through a 100-400 mesh sieve; preferably, through a 300-400 mesh sieve.

[0084] Moreover, in step a, when the film-forming agent is broken and mixed with the curing agent and the foaming agent, the following components can also be added for mixing: adhesion promoters, nanomaterials, powdery fillers, pigments or dyes, other One or more of the adjuvants. The sp...

[0103] Example 1: Ordinary (non-broken bridge) aluminum alloy profiles / doors and windows coated with the thermal insulation powder coating of the present invention

[0104] (1) Preparation of coatings, including:

[0105] 1. Prepare the coating for the surface layer according to the following components and parts by weight: epoxy resin 100; curing agent 4.70; foaming agent 0.3; leveling agent 1.52; adhesion promoter 3; nano-titanium dioxide 0.64; zirconia 5.12; mica powder 12; chrome yellow 5.22; iron oxide red 3.48; carbon black 0.70; other additives (light stabilizer used in this example) 0.50.

[0106] In this embodiment, the foaming agent is first ball-milled and then passed through a 100-400 mesh sieve. The film-forming epoxy resin was then crushed to 40 mesh, and the crushing speed was 1440 r / min. Then add it and other components into a high-speed mixer for mixing, and the speed of the mixer is 60r / min. After mixing for 15 minutes, enter the twin-screw extruder for mi...

Abstract

The invention discloses a heat-insulation heat-preservation powdered paint, a preparation method and a coating method of the heat-insulation heat-preservation powdered paint, a coating formed by using the coating method and application of the coating. The heat-insulation heat-preservation powdered paint comprises the following components in parts by weight: 90-100 parts of a film-forming agent, 1-10 parts of a curing agent, 0.1-2 parts of a foaming agent and 0.5-5 parts of a flatting agent, wherein the foaming agent is an inorganic component foaming agent or an organic component forming agent of which the decomposition temperature Td is between 120 DEG C and 220 DEG C. Ordinary aluminum alloy sections and aluminum alloy doors / windows using the heat-insulation heat-preservation powder coating have the advantages that no non-metallic material needs to be inserted between two aluminium products, the complexity of a coating process can be reduced and good heat insulation property can be ensured.
