Problems solved by technology

[0004] At present, the embossing process for wood-plastic composite profiles is mainly to use embossing machines for embossing, which belongs to the secondary processing of profiles. It is labor-intensive and time-consuming, which greatly wastes the production cost; on the other hand, using an embossing machine to emboss the surface of the wood-plastic composite material will seriously damage the wood-plastic composite material formed during the extrusion cooling process. Skinning, which is bound to have a negative impact on the mechanical properties of the profile

Embodiment 1

[0024] The processing equipment used in the original preparation of wood-plastic composite profiles is as follows: figure 1 As shown, it mainly includes a dryer 2, an extruder 3, a cooling and setting table 4, a tractor 5 and a cutting device 6, and the feed port of the dryer 2 is provided with a feeding cylinder 1 for feeding, and the drying The discharge port of the extruder 2 is connected with the feed port of the extruder 3. The cooling and shaping table 4 is provided with a calibrating die 41 and a cooling water tank 42. The calibrating die 41 is close to the head of the extruder 3. If necessary, use figure 1 If the profile prepared by the processing equipment shown is embossed, the embossing machine needs to be used for secondary processing. For this reason, the present invention proposes a kind of preparation method of wood-plastic composite profile, and the processing equipment that it adopts is as figure 2 as shown, figure 2 The processing equipment shown is in f...

Embodiment 2

[0041] The preparation process of this embodiment is basically the same as that of Example 1, the only difference is that the color masterbatch is added in step ②, and the granular material and the color masterbatch are firstly mixed according to actual requirements; then the prepared particles Granular materials and color masterbatch are put into the dryer 2 through the upper barrel 1, and the prepared granular materials and color masterbatch are dried, and the drying temperature does not exceed 85°C. The profiles made by adding color masterbatch are not only rich in color, but also do not need to be painted. Here, the color masterbatch directly adopts the commercially available color masterbatch.

Abstract

The invention discloses a method for preparing wood plastic composite material sections with embossing, which has the advantages that: an embossing processing procedure is increased between shaping processing and cooling processing; the sections subjected to shaping processing are still in a softened and molten state, an embossing die arranged between a shaping die and a cooling water tank is used for performing embossing processing on the sections subjected to shaping processing, and the embossed sections are subjected to subsequent cooling, so crusts formed in the process of cooling the wood plastic composite material sections cannot be damaged; therefore, the excellent mechanical properties of the wood plastic composite material sections can be kept. Because the embossing die arranged between the shaping die and the cooling water tank is used for embossing processing, the sections are not needed to be conveyed by manpower in the embossing process, and are conveyed through mechanical transmission so as to greatly save manpower; and the product extruding and embossing are synchronously carried out, so the production and processing time is greatly saved, and the production cost iseffectively saved.

Description

technical field [0001] The invention relates to a profile processing technology, in particular to a method for preparing an embossed wood-plastic composite material profile. Background technique [0002] With the reduction of natural forest area in my country and the implementation of forest protection policies, the price of high-quality wood is getting higher and higher, the increase of waste in the wood processing industry and the increase in the demand for forest products in the world have made the forest product industry bring unprecedented benefits to the society. pressure. The proposal of wood-plastic composite material solves this problem well. It not only has the texture of wood, but also has the excellent performance of plastic. It meets people's pursuit of an elegant and comfortable living environment while protecting the environment. Therefore, At present, wood-plastic composite materials can be used as the best substitute for wood. [0003] At present, in the de...
