DETAILED DESCRIPTION

[0022] To make the technical means, features, purposes and effects of the present invention easy to understand, detailed embodiments are combined hereinafter to further elaborate the techniques of the present invention.

[0023] As shown in FIGS. 1-4, the wiring trough of the present invention comprises a trough body 1 and a trough cover 2 arranged on the trough body 1, wherein the two ends of the trough body 1 are respectively provided with a first clamping portion, and the two ends of the trough cover 2 are respectively provided with a second clamping portion 4. The trough body 1 and the trough cover 2 are connected in a mutual clamping manner through the first clamping portion 3 and the second clamping portion 4. A channel for receiving a wire is form in the middle of the trough body 1 and the trough cover 2. A first decoration lug 6 is arranged on one side of the first clamping portion 3, and a second decoration lug 5 is arranged on one side of the second clamping portion 4.

[0024] The cross section of the trough cover 2 is in an arc shape or a wave shape. The trough body 1 and the trough cover 2 are made of PVC plastic.

[0025] A method for preparing the wiring trough, comprising the steps of: Step 1: selecting raw materials: weigh 99 parts of PVC resin, 3 parts of a combined heat stabilizer, 4 parts of an anti-impact agent, 2 parts of a lubricant and 4 parts of a flame retardant, and then feeding them into a mixing mechanism to obtain a mixture;

[0026] Step 2: feeding the mixture obtained in step 1 into a heating device for heating, wherein the heating temperature is 110° C.-120° C., then cooling and letting it sit for 24 hours;

[0027] Step 3: feeding the mixture processed in step 2 into two twin-screw extruders for extrusion, plasticizing and molding, thereby enhancing the wood feeling of the wiring trough and achieving the multi-color of the wiring trough; finally, automatically cutting to obtain finished wiring troughs.

[0028] In step 3, the extrusion temperature of the twin-screw extruder is 150° C.-180° C.

[0029] In step 1, the flame retardant is a magnesium hydroxide halogen-free flame retardant.

[0030] In step 1, the lubricant is composed of stearic acid, oxidized polyethylene wax and stearic acid glyceride in a mass ratio of 1:1:2.
