preparation example Construction

[0047] In terms of the preparation of EPS recycled granules, the technological process is to sort and wash the PS foam plastics first, then dry them, then grind them into powder, and then granulate them.

[0048] In terms of granulation of recycled profiles, the technological process is to first classify the scraps and scraps by color, then crush them, and then granulate them.

[0049] For the granulation step in the preparation process of EPS recycled granules and recycled profile granules, a co-rotating parallel twin-screw extruder with a screw diameter of 36 and a screw length-to-diameter ratio of 36:1 is used. The process parameters are as follows:

[0050] Main engine speed: 300~400r / min, feeding speed: 75~100r / min, cylinder zone 1: 135~145℃, cylinder zone 2: 140~150℃, cylinder zone 3: 145~155℃, machine Cylinder zone 4: 150~160℃, cylinder zone 5: 150~160℃, cylinder zone 6: 155~165℃, cylinder zone 7: 155~165℃, cylinder zone 8: 155~165℃, machine Cylinder zone 9: 160-170°C,...

Embodiment 1

[0052] Take 75 parts of EPS recycled granules and 25 parts of HIPS (high impact polystyrene) granules and add them to the high-speed mixer, then add 0.8 parts of 40# industrial white oil, start the low-speed switch and stir for 10 minutes, then add the flame retardant (hexabromocyclic 1.0 parts of dodecane), 0.5 parts of baking soda, 0.1 part of AC foaming agent, 0.1 part of anti-ultraviolet auxiliary agent, 2 parts of foaming aid, stirring at low speed for 15 minutes and discharging.

[0053] 40# industrial white oil is selected because of its high viscosity, powdered additives such as foaming agent can be evenly adsorbed on the surface of PS particles treated with 40# industrial white oil.

[0054] Take 80 parts of HIPS particles and 20 parts of PS (general-purpose resin, MI: 1.0-4.0g / 10min) and add them to the high mixer, then add 0.8 parts of DOP, start the low-speed switch and stir for 5 minutes, then add 0.1 parts of PE-wax, coloring 1.0 part of the agent was stirred at ...

Embodiment 2

[0061] Take 50 parts of EPS recycled granules and 50 parts of HIPS (high impact polystyrene) granules and add them to the high-speed mixer, then add 0.8 parts of 40# industrial white oil, start the low-speed switch and stir for 10 minutes, then add the flame retardant (hexabromocyclic 2.0 parts of dodecane), 1.5 parts of baking soda, 0.5 parts of AC foaming agent, 1.0 parts of anti-ultraviolet auxiliary agent, and 4 parts of auxiliary foaming agent, stirring at low speed for 15 minutes and discharging.

[0062] 40# industrial white oil is selected because of its high viscosity, and the powdered additives such as foaming agent can be evenly adsorbed on the surface of PS particles treated with white oil.

[0063] Take 80 parts of HIPS particles and 20 parts of PS (general-purpose resin, MI: 1.0-4.0g / 10min) and add them to the high-speed mixer, then add 0.8 parts of DOP, start the low-speed switch and stir for 5 minutes, then add 0.5 parts of PE-wax, coloring 2.0 parts of the age...

Abstract

The invention relates to a transom proximate matter and also relates to a preparation method thereof. A foam Ps transom proximate matter comprises a base material which is characterized in that the base material comprises the following raw materials according to the weight by parts: 50-75 parts of EPS regeneration particles, 25-50 parts of HIPS, 0.5-1.0 parts of saleratus, 0.1-1.5 parts of AC vesicant, and 2-4 parts of blowing promoter. The foam PS transom proximate matter prepared by a coextrusion method inherits the advantages of wood and micro expanded materials and overcomes shortcomings of the two materials. The raw material of the base material of the foam Ps transom proximate matter uses expandable polystyrene (EPS) in a great measure, thoroughly solves so called 'white foam' pollution in manufacturing production and current production; and scrapping materials can be recycled and reused in course of processing.

Description

technical field [0001] The present invention relates to a ventilation window profile, and also relates to a manufacturing method of the ventilation window profile. Background technique [0002] At present, most of the ventilation windows in China are made of wood or PVC micro-foaming materials. The ventilation windows made of wood have a series of advantages such as light weight and beautiful appearance. However, my country is a country with relatively scarce forest resources, and a large number of forest resources will be endangered. The interests of future generations are expressly prohibited by the law of our country, and because of the wood structure itself, it is very easy to absorb water and rot during use, so we must treat the surface before use, such as coating the wood surface with waterproof Paint or brush a layer of waterproof tung oil, etc. Surface treatment consumes a lot of manpower and material resources, thus increasing the manufacturing cost. [0003] The tr...
