Problems solved by technology

[0005] At present, there are many PVC composite materials that can be applied to yachts, but in order to achieve aesthetics, they are often spray-painted directly on the surface of the PVC film, and yachts are not like advertising spray-painted cloth that stands still. Scratching occurs, which can easily lead to flaws in an exquisite pattern; in addition, traditional PVC composite materials for yachts are often prone to "wicking" phenomenon, which affects their aesthetics and service life; traditional PVC composite materials for yachts The material has defects such as insufficient peel strength and easy aging, which seriously affect its use

Embodiment 1

[0068] A production process of a composite material for a yacht, the steps of which are:

[0069] (1) The transparent elastic PVC mask layer 1, the spray-painted PVC film layer 2, and the black base film layer 4 are respectively prepared through the following procedures:

[0070] Screening → batching → high-speed kneading at 195°C → banburying at 200°C → rough refining at 195°C → refining at 205°C → extrusion and filtration at 180°C → four-roll calendering, 1#180°C, 2#185°C, 3#170°C, 4 #163°C → 160°C extraction → 180°C heating → biaxial stretching → 150°C heating → cooling and shaping → trimming → coiling; Among them, the spray-painted PVC film layer 2 can be photo-painted with various exquisite patterns according to needs.

[0071] The raw material of transparent elastic PVC mask layer 1 is composed of: 100 parts by weight of PVC resin powder with degree of polymerization K=80, 5 parts of thermoplastic polyurethane, 40 parts of citric acid ester plasticizer, auxiliary plastic...

Embodiment 2

[0087] A production process of a composite material for a yacht, the steps of which are:

[0088] (1) The transparent elastic PVC mask layer 1, the spray-painted PVC film layer 2, and the black base film layer 4 are respectively prepared through the following procedures:

[0089] Screening → batching → high-speed kneading at 200°C → internal mixing at 205°C → rough refining at 195°C → refining at 205°C → extrusion and filtration at 185°C → four-roll calendering, 1#185°C, 2#190°C, 3#175°C, 4 #165°C→162°C Extraction→185°C Heating→Biaxial Stretching→155°C Heating→Cooling and Shaping→Edging Trimming→Coiling; Among them, the spray-painted PVC film layer 2 can be photo-painted with various exquisite patterns according to needs.

Abstract

The invention relates to a production technology of a composite material for a yacht, comprising the following steps: firstly using a padding-bonding all-in-one machine to pad a mesh cloth layer with a PVC resin-pasting adhesive and drying and preheating; then synchronously bonding the mesh cloth layer with an ink-jet printing film layer and a surface film layer at 190-200 DEG C, wherein the ink-jet printing film layer is arranged between the mesh cloth layer and the surface film layer; bonding the other side surface of the mesh cloth layer with a bottom film layer; and finally cooling to mold, and trimming and reeling to obtain the composite material for the yacht. According to the invention, by preferred formula of the surface film layer, a transparent elastic film with excellent performance is obtained; by using the PVC resin-pasting adhesive, the peeling strength, tearing strength, handle resilience and other physical properties are good; by completing the bonding of the multiple film layers and the mesh film layer in one step, the damage to the PVC film layer caused by multi-time heating and cooling is reduced, and the product performance is raised.

Description

technical field [0001] The invention belongs to the field of new textile materials, and in particular relates to a production process of composite materials for yachts. Background technique [0002] Yacht is a high-grade durable consumer goods for water entertainment. It integrates navigation, sports, entertainment, leisure and other functions to meet the needs of individuals and families to enjoy life. With the rapid development of the economy and the improvement of people's living standards, people are turning their interest to yachts. [0003] my country is a large oceanic country with 90,000 lakes, 6,500 islands, and 18,000 kilometers of coastline, and has the natural and geographical conditions for yacht consumption. The 2011 China (Shanghai) International Boat Show ended in Shanghai. During the four-day show, the turnover of yachts alone exceeded 1 billion yuan. The strong momentum of yacht sales once again indicates that yachts may soon become the "commanding heigh...
