preparation example Construction

[0070] In order to manufacture PVC leather that does not use adhesive bonding when being applied to automobile curtains, the present invention also provides a kind of preparation method of above-mentioned PVC leather: adopt calender molding process, comprise the following steps:

[0071] Step 1: Prepare the raw materials required for the foam layer and the surface layer respectively according to the weight ratio.

[0072] The foam layer includes the following raw materials in parts by weight: 38-50 parts of SG-5 type PVC resin, 19-25 parts of plasticizer, 23-30 parts of filler, 0.2-0.3 parts of foam stabilizer, 0.9-0.9 parts of foaming agent 1.2 parts, 1-1.3 parts of stabilizer, 0.6-0.9 parts of flame retardant, 0-5 parts of pigment.

[0073] The surface layer includes the following raw materials by weight: 48-65 parts of SG-3 type PVC resin, 23-32 parts of plasticizer, 10-13 parts of filler, 1.5-2 parts of stabilizer, 1.5-2 parts of flame retardant parts, 0-5 parts of pigmen...

Embodiment 1

[0088] Prepare the raw materials required for the foaming layer and the surface layer according to the weight ratio, put them into a high-speed stirring pot and stir at high speed for 5 minutes to obtain the foaming layer mixed powder and the surface layer mixed powder, and the mixed powder is successively banburyed, The foam layer and surface layer are obtained by kneading, extrusion, and calendering. The foam layer and surface layer are placed on the base fabric layer in turn for lamination, and then the laminated semi-finished product is foamed and embossed, and finally the surface is treated with an environmental protection agent. Process and dry to obtain PVC leather, and further use the PVC leather without adhesive to make car blinds.

[0089] The raw materials of the foam layer formula include by weight: 44 parts of SG-5 type PVC resin, 22 parts of plasticizer, 27 parts of filler, 0.24 parts of foam stabilizer, 1 part of foaming agent, 1.1 parts of stabilizer, pigment 4...

Embodiment 2

[0095] Prepare PVC leather with the method described in application example 1, difference is:

[0096] The raw materials of the foam layer formula include by weight: 50 parts of SG-5 type PVC resin, 20 parts of plasticizer, 20 parts of filler, 0.3 part of foam stabilizer, 1.2 parts of foaming agent, 1.3 parts of stabilizer, pigment 4 parts, 0.9 parts of flame retardant.

[0097] The surface layer formulation raw materials include by weight: 65 parts of SG-3 type PVC resin, 23 parts of plasticizer, 10 parts of filler, 1.5 parts of stabilizer, 0 part of pigment, and 1.6 parts of flame retardant.

[0098] The melting temperature of the surface layer is 162°C, and the melting temperature of the foam layer is 147°C.

[0099]The PVC leather has good mechanical properties and high flame retardancy. The flame retardancy rate is 35mm / min. After it is made into a car curtain, the VOC is low and the bonding effect is good. Applying a force of 10KG from the direction of pulling out the c...

Abstract

The invention discloses PVC leather and a manufacturing method and application thereof. The PVC leather comprises base fabric layers, a foam layer and a surface layer from inside to outside. The surface layer has a melting temperature higher than the melting temperature of the foam layer. The foam layer in the molten state can penetrate the base fabric layer. When used to make a car curtain, the PVC leather bypasses a reel of the curtain. The foam layer is in the molten state and the surface layer is not molten in the high-frequency heat sealing. Under the pressure, the molten foam layer penetrates the base fabric layer and enters the gap between the two base fabric layers and the layers are molten into a whole without a binder so that the PVC leather is environmentally friendly and has good adhesion effects and mechanical strength.

Description

technical field [0001] The invention belongs to the field of artificial leather, and in particular relates to a PVC leather and a production method and application thereof. Background technique [0002] With the rapid development of the automobile industry, especially the increasing use of MPV and SUV cars, people's demand for covering curtains has further increased. Installing covering curtains can effectively protect the privacy and safety of personal items and prevent the Seat personnel can spy on the personal belongings in the trunk, and at the same time prevent the tragedy of stealing valuables from smashing windows; improve the neat and generous image of the vehicle, and make it easier to use the space rationally; Put some dolls, decorations and other things to play a better decorative role. [0003] Currently, the main materials for covering curtains are canvas and leather. Canvas has the disadvantages of being not waterproof, not resistant to dirt, not easy to clean...
