CN102599028A - Novel synthetic wood greenhouse frame production process - Google Patents

Abstract

The invention relates to a novel synthetic wood greenhouse frame production process, which aims to overcome defects in the prior art. The greenhouse frame adopting the novel synthetic wood greenhouse frame production process has the advantages of favorable toughness, tension resistance, ultraviolet ray resistance and high intensity. The frame production process comprises the process flows of screening materials, mixing, pelletizing, molding and the like.

Description

A kind of novel synthetic wood big-canopy framework production technology

Technical field

The present invention is specifically related to a kind of novel synthetic wood big-canopy framework production technology.

Background technology

Along with developing rapidly of China's agricultural economy, plastic greenhouse miscellaneous is poured into market, mainly contains type shape such as steel skeleton, bamboo ribs frame and cement skeleton; They are the products that traditional manufacturing technique is produced, and its product is difficult for reclaiming, and transportation is difficult; The also price that has is expensive, lacks in the market a kind ofly can produce good toughness, tension; Antiultraviolet, the big-canopy framework production technology that intensity is high.

Summary of the invention

The object of the invention is intended to overcome the defective of prior art, adopts novel synthetic wood big-canopy framework manufacture craft, a kind of good toughness is provided, tension, antiultraviolet, the big-canopy framework that intensity is high.

For realizing above-mentioned purpose, the technical scheme that the present invention adopts is:

A kind of novel synthetic wood big-canopy framework production technology is characterized in that, may further comprise the steps:

1) sieve material;

2) puddle;

3) granulation;

4) moulding.

Said step 2) further comprising the steps of:

2.1) bright olefin(e) acid resin powder, PVC powder and plant stalk powder are at high temperature fully stirred;

2.2) when temperature rises to 60 ℃, add olefinic organic high-temperature stabiliser and calcium stearoyl zinc stabilizer and fully stir;

2.3) when temperature rises to 90 ℃, add ACR530 foaming control agent and HBA-401A PVC blowing agent and fully stir;

2.4) when temperature rises to 95 ℃, add PE wax and fully stir;

2.5) when temperature rises to 118 ℃, stir the discharging that finishes.

The prilling temperature of said step 3) is at 180 ℃.

The present invention is with respect to prior art, and the big-canopy framework of producing has good toughness, tension, antiultraviolet, the beneficial effect that intensity is high.

Embodiment

Below in conjunction with specific embodiment the present invention is done and to further describe:

A kind of novel synthetic wood big-canopy framework described in the invention carries out the screening of big-canopy framework material earlier, and bright olefin(e) acid resin powder, PVC powder and plant stalk powder are at high temperature fully stirred; When temperature rises to 60 ℃, add olefinic organic high-temperature stabiliser and calcium stearoyl zinc stabilizer and fully stir; When temperature rises to 90 ℃, add ACR530 foaming control agent and HBA-401APVC blowing agent and fully stir; When temperature rises to 95 ℃, add PE wax and fully stir; When temperature rises to 118 ℃, stir the discharging processing and manufacturing particle that finishes, again particulate material is extruded extrusion modling under 180 ℃ of high temperature.

The big-canopy framework that this explained hereafter goes out, superior performance, waterproof, fire prevention, mothproof, nontoxic, it is high to improve intensity, the tension antiultraviolet, and nontoxic, exempt to coat with lacquer one-shot forming, particularly heat insulation effect is best, and heat insulation effect is compared traditional booth thermal insulation can improve 8 ℃-9 ℃.

More than be the specific descriptions to this programme, obviously, any change of under the inventive concept of this programme, being made all will fall in protection scope of the present invention.
