Embodiment 1

[0027] The linear low-density polyethylene (LLDPE, 7047) is used as raw material, and industrial pigment (reduced bright green FFB) is added, and the added amount accounts for 0.8% of the linear low-density polyethylene (LLDPE) according to the weight percentage.

[0028] The processing steps are as follows:

[0029] The raw materials are stirred, and the raw materials are respectively added into a high-speed mixer, stirred and mixed, and the stirring speed is 5000 rpm, and the time is 50 minutes.

[0030] High temperature and high pressure injection molding. Put the mixed raw materials into a high-temperature and high-pressure injection molding machine, and perform injection molding at a temperature of 180° C. and a pressure of 2 MPa.

[0031] Injection molding. The injection molding material is added to the mold cast according to the shape of the product, and is shaped by the mold.

[0032] Composite, bonding non-woven fabric and heat-resistant non-slip mesh on the bottom...

Embodiment 2

[0037] The linear low-density polyethylene (LLDPE, 7540) is used as raw material, and industrial pigment (reduced olive green B) is added, and the added amount accounts for 0.01% of the linear low-density polyethylene (LLDPE) according to the weight percentage.

[0038] The processing steps are as follows:

[0039] The raw materials are stirred, and the raw materials are respectively added into a high-speed mixer, stirred and mixed, and the stirring speed is 1000 rpm, and the time is 150 minutes.

[0040] High temperature and high pressure injection molding. Put the mixed raw materials into a high-temperature and high-pressure injection molding machine, and perform injection molding at a temperature of 170° C. and a pressure of 0.5 MPa.

[0041] Injection molding. The injection molding material is added to the mold cast according to the shape of the product, and is shaped by the mold.

[0042] Composite, bonding non-woven fabric and heat-resistant non-slip mesh on the botto...

Embodiment 3

[0047] The linear low-density polyethylene (LLDPE, 7042) is used as a raw material, and an industrial pigment (phthalocyanine green G) is added, and the added amount accounts for 2% of the linear low-density polyethylene (LLDPE) according to the weight percentage.

[0048] The processing steps are as follows:

[0049] The raw materials are stirred, and the raw materials are respectively added into a high-speed mixer, and stirred and mixed at a stirring rate of 10000 rpm for 5 minutes.

[0050] High temperature and high pressure injection molding. Put the mixed raw materials into a high-temperature and high-pressure injection molding machine, and inject them under the conditions of a temperature of 190° C. and a pressure of 5 MPa.

[0051] Injection molding. The injection molding material is added to the mold cast according to the shape of the product, and is shaped by the mold.

[0052] Composite, bonding non-woven fabric and heat-resistant non-slip mesh on the bottom surfa...

Abstract

The invention relates to a method for producing linear low-density polythene grass pad. Wherein, it uses linear low-density polythene grass pad as material, uses industrial dope; and the production comprises that mixing materials, injecting at high temperature and high pressure, combining, demoulding, finishing, coiling and packing. And the invention uses environment friend material, without toxicity and irritant odor. And it has long service life and can be recycled.

Description

technical field [0001] The invention relates to a method for preparing floor mats for removing dust and dirt on shoe soles at doors, or for places with water such as bathrooms, in particular to a method for preparing lawn-shaped linear low-density polyethylene mats. Background technique [0002] In daily life, the commonly used plastic floor mat materials are polyvinyl chloride (pvc). According to the information currently available, polyvinyl chloride is a polymer called vinyl chloride chemical substance. Vinyl chloride itself is harmful to the human body. Although its polymer, polyvinyl chloride, is harmless in principle, any chemical substance The polymerization of PVC is not complete, so a certain amount of vinyl chloride is not completely polymerized, but it cannot be separated from it. These unpolymerized vinyl chloride is the "culprit" of carcinogenicity in PVC materials. [0003] At the same time, since PVC itself is relatively hard, plasticizers are generally added...
