preparation example Construction

[0051] A method for preparing an artificial leather surface layer material for furniture and building materials, comprising the following steps: weighing the first TPO, the second TPO, polyethylene, polypropylene, fillers and auxiliary agents, and putting them into an internal mixer for internal mixing , the banburying temperature of setting internal mixer is 160-190 ℃, the initial electric current of banburying is 260-320A, the electric current when unloading is 180-240A, obtains final product.

[0052] The internal mixing of raw materials under this condition can strengthen the internal mixing and shorten the mixing cycle. At the same time, the heat generated at this speed will not be too high, which will have little effect on the viscosity of the raw materials and will not reduce the mechanical shearing effect. It is conducive to the full dispersion of each component; in addition, there will be no raw material burning phenomenon, and there will be no raw material crushing ph...

Embodiment 1-4

[0065] An artificial leather comprising a surface layer and a substrate layer bonded upper and lower. The composition and dosage (parts by weight) of the artificial leather of Examples 1-4 are shown in Table 1 below.

[0066] The formula table of the artificial leather of table 1 embodiment 1-4

[0067]

[0068] A kind of preparation method of artificial leather, comprises the following steps:

[0069] Mixing step: Weigh the first TPO, the second TPO, polyethylene, polypropylene, fillers and additives in the formula, put them into the internal mixer for internal mixing, set the internal mixing temperature of the internal mixer to 160-190 ℃, the initial current of banburying is 260-320A, and the current during unloading is 180-240A to obtain the raw material of the first surface layer;

[0070] Milling step: unload the raw materials of the first surface layer into the mill, set the temperature of the mill to 160-190°C, further knead and plasticize, and obtain the raw mater...

Abstract

The invention discloses an artificial leather surface layer material for home building materials. The artificial leather surface layer material comprises, by weight, 35-55 parts of first TPO, 15-35 parts of second TPO, 5-15 parts of polyethylene, 10-25 parts of polypropylene, 0-10 parts of a filler and 0.1-0.5 part of an assistant. The artificial leather surface material of home building materialshas a simple composition, different composite substrates can be selected according to the hardness need to obtain products having different hardness values, the hardness can be easily controlled to meet the needs of different consumers, and the products have good heat resistance, good weatherability and good mechanical properties. The invention also discloses a preparation method of the artificial leather surface layer material for home building materials. The preparation method has the advantages of short flow, simplicity and safety in operation, and low cost. The invention also discloses anartificial leather. The artificial leather has the advantages of flexibility in adjustment of the hardness, wide application range, and durability. The invention further discloses a production methodof the artificial leather. The production method has the advantages of few steps, simple process, safety in operation, and low cost.

Description

technical field [0001] The invention relates to the technical field of artificial leather, in particular to an artificial leather surface layer material for furniture and building materials, a preparation method and application thereof. Background technique [0002] Olefin thermoplastic elastomers include TPO and TPV (Thermoplastic Vulcanizate). Thermoplastic polyolefin elastomer (TPO) is a blend of soft segment (more than 20%) rubber and hard segment polyolefin. Generally, the components of rubber are ethylene propylene diene monomer (EPDM), nitrile rubber (NBR), butyl rubber (IIR) and natural rubber (NR); the components of polyolefins are mainly polypropylene (PP) and Polyethylene (PE). Currently used more is the blend of EPDM and PP, also known as modified polypropylene or modified polyethylene. [0003] The largest application field of polyolefin thermoplastic elastomers is the automotive industry. In automotive exterior parts, it is mainly used for bumpers, radiators,...
