Problems solved by technology

[0003] Among them, the main component of the rubber material is natural rubber. This raw material is collected by hand, and the output is small. Although it has the advantages of wear resistance, heat resistance, tear resistance, bending resistance and crack resistance, good air tightness, high strength, and light weight, etc., However, the rubber preparation process is complicated, resulting in high cost of the kayak, and it is not beautiful enough
The main component of a PVC fabric kayak is plastic-coated fabric, which can be mass-produced on an assembly line, so the cost is low. However, the kayak made of this material has poor wear resistance and scratch resistance, and often needs to be repaired.

Embodiment 1

[0051] 1) Take the following raw materials by weight percentage to prepare the inner coating:

[0052]

[0053]

[0054] 2) Get the following weight percent raw materials to make a calendered film as the outer coating:

[0055]

[0056] The thickness of the calendered film was 0.2 mm.

[0057] 3) After the above raw materials are blended, put them into the mixing tank and stir them evenly with a mixer at room temperature. Since there will still be a small amount of particles in it, use a three-roller grinder to grind the mixture. It can be used after grinding for 8-10 minutes. .

[0058] 4) After the gray cloth is cleaned, it is flattened and dried by an ironing tractor at a drying temperature of 130°C.

[0059] 5) Apply the inner coating prepared in step 1) evenly on both sides of the gray cloth treated in step 4) by padding and sizing, and then plasticize in an oven.

Abstract

Canvas for a canoe comprises gray fabric, an inner coating and an outer coating, wherein the gray fabric is filament woven plain cloth, the inner coating is prepared from, by weight, 25-35% of polyvinyl chloride paste resin, 10-30% of dioctyl phthalate, 10-20% of dioctyl adipate, 8-10% of polyester type plasticizer, 20-35% of light calcium carbonate, 2-5% of lead oxide phosphite hydrate, 1-3% of titanium dioxide, 0.1-1.5% of preservative, 0.5-3% of flame retardant and 1-2% of pigment, and the inner coating is 0.5-1 mm thick; the outer coating is a polypropylene calendering film and is prepared from, by weight, 60-70% of polypropylene resin, 0.3-0.8% of ultraviolet light absorber, 15-30% of flame retardant, 10-15% of glass fiber and 0.6-1% of pigment, and a polyamide film which is purchased from market and 0.2-0.4 mm thick can also be adopted. A method for preparing the canvas mainly comprises the steps of padding and sizing, plasticizing in an oven, surface flattening and cooling into coils.

Description

technical field [0001] The invention relates to a canvas, in particular to a canvas for kayaking and a preparation method thereof. Background technique [0002] Existing materials for making inflatable kayaks can be roughly divided into two classes, namely rubber materials and PVC cloth materials. [0003] Among them, the main component of the rubber material is natural rubber. This raw material is collected by hand, and the output is small. Although it has the advantages of wear resistance, heat resistance, tear resistance, bending resistance and crack resistance, good air tightness, high strength, and light weight, etc., However, the complicated rubber preparation process causes the cost of kayaking to be high, and it is not attractive enough. The main component of PVC cloth kayaks is plastic coated cloth, which can realize mass production on the assembly line, so the cost is low, but the kayaks made of this material have poor wear resistance and scratch resistance, and o...
