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

preparation example Construction

[0077] The present invention simultaneously provides the preparation method of the coating of above-mentioned primer coating, comprises the steps: a, after film-forming agent is crushed, carry out with solidifying agent, nanometer material, powdery filler, leveling agent, pigment or dyestuff and other auxiliary agent Mixing; b. After mixing the mixed raw materials with an extruder, discharge, cool to room temperature, and tablet; c. Send the compressed raw materials to the crushing and screening unit for crushing, grading and sieving, and crushing particle size 170-190 mesh, to obtain the powder of the paint for coating the surface layer; d, adding the hollow microspheres to the powder of the paint for coating the surface layer, and mixing thoroughly to obtain the paint for coating the bottom layer.

[0078] Wherein, the step a breaks the film-forming agent, and the crushing speed is 1440r / min-1450r / min, the purpose is to break the film-forming agent into a particle size of 40-...

Embodiment 1

[0095] Embodiment 1: Common (non-broken bridge) aluminum alloy profiles / doors and windows coated with heat insulation coating of the present invention

[0096] (1) Preparation of coatings, including:

[0097] 1. Prepare the coating for the surface layer according to the following components and parts by weight: epoxy resin 100; curing agent 4.70; leveling agent 1.52; nano-titanium dioxide 0.64; zirconia 5.12; mica powder 12; Carbon black 0.70; other additives 0.50.

[0098] In this example, the film-forming agent epoxy resin was crushed to 40 mesh at a crushing speed of 1440r / min, and then mixed with other components in a high-speed mixer at a speed of 60r / min. After mixing for 10 minutes, enter the twin-screw extruder for mixing. The temperature of the feed section of the extruder is 80°C, and the temperature of the discharge section is 115°C. Discharging, cooling to room temperature, and tableting. Then enter the crushing and screening unit, crush, classify and sieve, an...

Abstract

The invention discloses a heat insulating coating as well as a coating method, paint and preparing method thereof and an aluminum alloy sectional material and aluminum alloy doors and windows using the heat insulating coating. The heat insulating coating comprises a bottom layer coating and a surface layer coating, wherein a base material is directly coated with the bottom layer coating, and the surface layer coating is coated with the bottom layer coating; the bottom layer coating comprises the following components in percent by weight: 85-90% of surface layer paint, and 6-15% of hollow microsphere; the surface layer coating comprises the following components in parts by weight: 90-100 parts of a film-forming agent, 1-10 parts of a curing agent, 0.5-10 parts of nanometer material, 20-50 parts of powdery filler, 0.5-2 parts of a flatting agent, 1-1.5 parts of pigment or dye and 0.5-4 parts of other auxiliaries Through the application of the heat insulating coating, common aluminum alloy gates and windows can be enabled to have good heat insulating effects without inserting a non-metallic material (bridge-cutoff aluminum alloy sectional material) between two common aluminum alloy sectional materials. The insulating effects of the bridge-cutoff aluminum alloy sectional material can be further improved when the paint is applied to the bridge-cutoff aluminum alloy sectional material.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a thermal insulation coating and a coating method, a coating and a preparation method, and an application of the thermal insulation coating. Background technique [0002] At present, my country's building energy consumption accounts for 28-30% of the country's total energy consumption, while the energy consumption of doors and windows accounts for 50% of building energy consumption. Therefore, the key to building energy saving is the energy saving of doors and windows. The adoption of new energy-saving doors and windows and the energy-saving renovation of existing building doors and windows are the objective requirements of my country's energy situation and the inevitable trend of market development. [0003] Aluminum alloy doors and windows, plastic doors and windows, steel doors and windows, wooden doors and windows and other types of doors and windows are common in the build...
