Problems solved by technology

[0007] 1. The use of chemical preparations in ingredients often causes environmental pollution during product production and product use;
[0008] 2. The complex formula causes the high production cost of the product;
[0009] 3. After the service life of the product is over, the product is difficult to degrade
[0010] The composite materials in the prior art have various defects due to the limitation of their own ingredients, and it is difficult to adapt to the development trend and actual needs of today's composite materials.

Embodiment 1

[0055] as attached figure 1 Shown, a kind of production method of the environmental protection composite material described in claim 1 comprises the following steps:

[0056] 1) Prepare the mixed material, which includes: 40-60 parts of PVC, 10-60 parts of calcium powder, 0.1-40 parts of carbon powder, 1.5-4 parts of stabilizer, 1-5 parts of negative oxygen Ion powder, 0.1-5 parts of photo-oxygen catalyst, 0.2-1 parts of flame retardant, 0.1-5 parts of toughening agent, 0.1-3 parts of modifier and 1-15 parts of plant fiber powder;

[0057]2) Stir the material, use a mixer to stir the material, and the stirring time is 35-50 minutes;

[0058] 3) Exhaust the excess gas in the material, and use the vacuum pump to extract the excess gas in the mixer. The vacuum degree in the mixer is 0.07-0.09MPa;

[0059] 4) Material mixing, material melting, the melting temperature of the material is 170-190 ° C, using the mixing section of the foaming twin-screw extruder for material mixing, ...

Embodiment 2

[0074] as attached figure 2 As shown, after step 5) and before step 6), vacuum pumping of the molten material is also included. Except for this, other steps and implementation methods are the same as in Example 1.

[0075] Through vacuum pumping, the cross-section of the extruded molten material is in the shape of a flute. The molding material after this step helps to reduce the weight of the product; at the same time, it can save the molten material.

Abstract

The invention discloses an eco-friendly composite material. The eco-friendly composite material mainly comprises 40-60 parts by weight of PVC, 10-60 parts by weight of calcium powder, 0.1-4 parts by weight of carbon powder, 1.5-4 parts by weight of a stabilizing agent, 1-5 parts by weight of negative oxygen ion powder and 1-15 parts by weight of plant fiber powder. The eco-friendly composite material is environmentally friendly, can release negative oxygen ions, can improve air quality and can catalytically decompose poisonous and harmful gas and bacteria. Through use of degradable materials as main materials, the eco-friendly composite material can be easily decomposed.

Description

technical field [0001] The invention relates to a composite material, in particular to an environment-friendly composite material and a production method thereof. Background technique [0002] Composite materials are materials with new properties composed of two or more materials with different properties through physical or chemical methods on the macroscopic (microscopic) level. Various materials learn from each other in terms of performance and produce synergistic effects, so that the comprehensive performance of the composite material is better than that of the original constituent materials to meet various requirements. The matrix materials of composite materials are divided into two categories: metal and non-metal. Among them, non-metallic substrates mainly include synthetic resin, rubber, ceramics, graphite, carbon, etc. The development of modern high technology is inseparable from composite materials, and composite materials play a very important role in the develo...
