Problems solved by technology

The existing attached frames on the market are mainly divided into plastic-wood attached frames, wood attached frames and fiberglass attached frames according to their materials, but they all have some insurmountable shortcomings in production and use.
For example, the plastic-wood attached frame is relatively heavy and has poor nail holding power; the wooden attached frame is easily deformed and will be damaged by insects and ants; the fiberglass attached frame is poisonous and not suitable for indoor use

Embodiment 1

[0037] The manufacturing process of reinforced door and window frames includes the following steps:

[0038] (1) Melt 100 parts of high-density polyethylene plastic particles, 0.5 parts of crosslinking agent, 0.5 parts of rigidizer, 1 part of reinforcing fiber, and 5 parts of filler through a twin-screw extruder at high temperature and then extrude and granulate. The temperature is gradually increased from 120°C to 160°C inwards from the machine head, so that the molecular chains of the material are rearranged to obtain a premix, and each component is calculated by weight component;

[0039] (2) Add 0.5 parts of AC foaming agent and 1 part of lubricant, and at the same time, under the condition of process temperature of 60°C-80°C, stir and mix at a high speed to fully wrap the premix to obtain a new premix;

[0040] (3) The new premixed material obtained in step (2) is sent to the progressive extruder, and the temperature of the fuselage is gradually increased from 120°C to 16...

Embodiment 2

[0042] The manufacturing process of reinforced door and window frames includes the following steps:

[0043] (1) Melt 100 parts of polyvinyl chloride plastic particles, 2 parts of cross-linking agent, 0.7 parts of stiffening agent, 5 parts of reinforcing fiber, and 10 parts of filler through a twin-screw extruder at high temperature and then extrude and pelletize. Gradually increase from 120°C to 170°C inwards from the machine head, so that the molecular chains of the material are rearranged to obtain a premix, and each component is calculated by mass component;

[0044] (2) Add 1 part of AC foaming agent and 2.5 parts of lubricant, and at the same time, under the condition of process temperature of 60°C-80°C, stir and mix at a high speed to fully wrap the premix to obtain a new premix;

[0045] (3) The new premixed material obtained in step (2) is sent to the progressive extruder, and the temperature of the fuselage is gradually increased from 120°C to 170°C at the head, resu...

Embodiment 3

[0047] The manufacturing process of reinforced door and window frames includes the following steps:

[0048] (1) Melt 100 parts of FRP plastic particles, 3 parts of cross-linking agent, 1 part of stiffening agent, 10 parts of reinforcing fiber, and 15 parts of filler through a twin-screw extruder at high temperature and then extrude and pelletize. The first 120°C gradually rises inwards to 180°C, so that the molecular chains of the material are rearranged to obtain a premix, and each component is calculated by weight component;

[0049] (2) Add 2 parts of AC foaming agent and 4 parts of lubricant, and at the same time, under the condition of process temperature of 60°C-80°C, stir and mix at a high speed to fully wrap the premix to obtain a new premix;

[0050] (3) The new premixed material obtained in step (2) is sent to the progressive extruder, and the temperature of the fuselage is gradually increased from 120°C to 180°C at the head, resulting in a diameter of 0.01mm-0.5mm ...

Abstract

The invention discloses an enhanced door and window auxiliary frame. The enhanced door and window auxiliary frame is composed of a micro-foaming sheet material and a steel body embedded inside the micro-foaming sheet material; the micro-foaming sheet material comprises the following compositions: plastic particles, a cross-linking agent, a stiffening agent, reinforced fibers, an AC (Azodicarbonamide) foaming agent and a packing material. By the existence of a large number of bubbles in the micro-foaming material, the enhanced door and window auxiliary frame is low in density, light in weight and high in impact absorption loading capacity; by the steel body embedded inside the micro-foaming sheet material, the enhanced door and window auxiliary frame shows excellent cushioning capacity, and has the advantages of high heat insulation property, good sound insulation effect, acid and alkali resistance and good chemical stability.

Description

technical field [0001] The invention relates to a door and window frame, in particular to a reinforced door and window frame and a manufacturing method thereof. Background technique [0002] The frame attached to the door and window plays a role in determining the size and positioning of the door and window. Generally speaking, after the openings of the doors and windows of the building are built, the size is not standardized. After installing the attached frame, the processing size of the doors and windows can be measured more accurately, which is also conducive to the installation of the doors and windows, and the safety is better. At the same time, the use of attached frames reduces the expansion and contraction of plastic doors and windows due to thermal expansion and contraction. The existing attached frames on the market mainly include plastic-wood attached frames, wood attached frames and fiberglass attached frames according to their materials, but they all have some...
