Embodiment 1

[0024] The production of the attached frame material consists of the following raw materials in parts by weight: 100 parts of ASA / PVC material, 15 parts of PVC, 2 parts of processing aid, 2 parts of stabilizer, 1 part of titanium dioxide, 10 parts of calcium carbonate, and 0.1 parts of internal lubricant 0.1 part of external lubricant, 0.5 part of glass fiber yarn treated with silane-based sizing agent.

[0025] The energy-saving attached frame finally produced through this formula has a coefficient of thermal expansion and contraction of 15×10 -6 m / °C.

Embodiment 2

[0027] The production of the attached frame material consists of the following raw materials in parts by weight: 100 parts of ASA / PVC material, 30 parts of PVC, 3 parts of processing aid, 3 parts of stabilizer, 2.5 parts of titanium dioxide, 25 parts of calcium carbonate, and 0.5 parts of internal lubricant Parts, 0.5 parts of external lubricant, 10 parts of glass fiber filaments treated with silane-based sizing agent; and mix them.

[0028] The energy-saving attached frame finally produced through this formula has a coefficient of thermal expansion and contraction of 17.5×10 -6 m / °C.

Embodiment 3

[0030] The production of the attached frame material consists of the following raw materials in parts by weight: 100 parts of ASA / PVC material, 50 parts of PVC, 4 parts of processing aid, 4 parts of stabilizer, 4 parts of titanium dioxide, 40 parts of calcium carbonate, and 1 part of internal lubricant 1 part, 1 part of external lubricant, 20 parts of glass fiber filaments treated with silane-based sizing agent.

[0031] The energy-saving attached frame finally produced through this formula has a coefficient of thermal expansion and contraction of 21.3×10 -6 m / °C.

[0032] This shows that the formula component among the embodiment 1 can obtain best effect.

Abstract

The invention relates to a processing technology of a high-strength low-creep PVC energy-saving auxiliary frame. The processing technology comprises the following steps that 1, an auxiliary frame material is prepared by mixing, by weight, 100 parts of an ASA-PVC material, 15-50 parts of PVC, 2-4 parts of a processing auxiliary, 2-4 parts of a stabilizer, 1-4 parts of titanium dioxide, 10-40 parts of calcium carbonate, 0.1-1 part of an inner lubricant, 0.1-1 part of an outer lubricant and 0.5-20 parts of fiber glass filaments; 2, a mixture obtained in the step 2 is added into a plastic extruding machine to be plastified and extruded; 3, an extruding product obtained in the step 2 is contained in a mold to be shaped; 4, drying is conducted, wherein a product obtained in the step 3 is dried; 5, cutting is conducted. According to the processing technology, the problems that a general plastic auxiliary frame has obvious thermal expansion and cold contraction phenomena and is prone to deform are solved, the size and position of a door window can be determined, and the installation quality of the door window is more easily controlled.

Description

technical field [0001] The invention belongs to the field of building construction, and in particular relates to a processing technology of high-strength and low-creep PVC energy-saving frame attached. Background technique [0002] The traditional door and window installation method belongs to wet installation. After the door and window openings of the building are completed, the door and window construction personnel directly install the main frame, and finally install the door and window glass and seal it with glue in the later stage of decoration. However, there is a long period of time between the completion of the installation of the main frame of doors and windows and the later stage of decoration. The main frame of doors and windows is exposed to the construction site for a long time, and it will inevitably be affected by other constructions, resulting in damage, deformation, and surface corrosion of the frame. and pollution issues. In the civil construction stage, t...
