Embodiment 1

[0056] The present embodiment 1 provides the preparation method of the first antifouling layer raw material, comprising the following steps:

[0057] Pass 150g acetone in the reactor, logical N 2 Protection, start stirring, the stirring speed is 250r / min, heat up to 85°C, add 20g perfluorodecyltrimethoxysilane, 5g butyl orthosilicate, 5g modified fumed silica and 0.5g diacetic acid in 3h Dibutyltin was poured into the reaction kettle and kept warm for 3 hours to obtain the first product 1.

Embodiment 2

[0059] This embodiment 2 provides the preparation method of the first polyolefin seat, comprising the following steps:

[0060] Step 1. Mix 95g of polypropylene raw material and 5g of polypropylene grafted maleic anhydride, stir at 25°C, the stirring speed is 300r / min, and the stirring time is 20min, to obtain the raw material of polypropylene seat body;

[0061] Step 2. Spray the anti-fouling layer raw material provided in Example 1 into the injection molding mold of the injection molding machine, then melt and extrude the polypropylene seat body raw material provided in step 1, and inject it into the mold sprayed with the anti-fouling layer raw material , heat preservation and pressure for 10 minutes, after cooling in the air, a polypropylene seat is obtained;

[0062] Wherein, the temperature of the melt extrusion in this embodiment is 260°C, the screw speed of the melt extrusion is 30r / min, the mold temperature is 75°C, and the cooling temperature of the air is 25°C. .

Embodiment 3

[0064] This embodiment 3 provides the preparation method of the second polyolefin seat, the difference between the preparation method and embodiment 2 is: step 1, 95g polypropylene raw material, 4gPP color masterbatch, 5g polypropylene graft maleic anhydride Mix and stir at 25° C., the stirring speed is 300 r / min, and the stirring time is 20 minutes to obtain the raw material of the polypropylene seat body.

Abstract

The invention belongs to the technical field of plastic seats, and particularly relates to a polyolefin seat as well as a preparation method and application thereof. The polyolefin seat provided by the invention comprises the polyolefin seat body and the antifouling layer, the antifouling layer covers the surface of the polyolefin seat body, and polyolefin grafted with polar groups in the polyolefin seat body improves the surface energy of the polyolefin seat and is chemically bonded with groups in the antifouling layer; the adhesive force between the antifouling layer and the polyolefin seat body is improved, so that the technical problems that the antifouling layer on the surface of the polyolefin seat is easy to fall off and the durability is poor are solved.

Description

technical field [0001] The application belongs to the technical field of plastic seats, in particular to a polyolefin seat and its preparation method and application. Background technique [0002] Seats in large public places such as gymnasiums, bus stations, and railway stations are prone to stains on the surface of the seats during long-term use, which affects the appearance. Moreover, large public places have a large flow of people and a large area. Cleaning the seat surface stains or Replacing a new seat is time-consuming and labor-intensive; therefore, the surface of the seat in a large public place will be covered with an anti-fouling layer to reduce the generation of stains, reduce the consumption of manpower and material resources, and improve the aesthetics of the seat. [0003] However, on the one hand, since the antifouling layer and the seat belong to two materials, the compatibility and adhesion between the antifouling layer and the seat of different materials a...
