Abstract

The invention relates to a heatproof oilcloth and a preparation method, the heatproof oilcloth comprises linen and a coating, the coating comprises the following components by weight ratio: 3-5 parts of ethyl acetate, 2-5 parts of polyvinyl alcohol, 3-4 parts of rosin resin, 5-7 parts of diglyceride, 11-14 parts of polyurethane and 12-15 parts of polyethylene. The heatproof oilcloth is prepared by the steps of preparing the coating, brushing and drying. The heatproof oilcloth has good heat resistance performance.

Description

A kind of heat-resisting oilcloth and preparation method thereof

Technical field

The present invention relates to a kind of oilcloth and preparation method thereof, particularly relate to a kind of heat-resisting oilcloth and preparation method thereof.

Background technology

The scope of application of oilcloth is wider, can be as rainproof tarpaulin, tent cloth etc.In the use procedure of oilcloth, except having the function of waterproof, also need to possess certain resistant to elevated temperatures function.Because under certain conditions, under hygrothermal environment, the heat resistance of oilcloth has larger impact to the serviceability of oilcloth.Improve the heat resistance of oilcloth, can strengthen the serviceability of oilcloth, expand the scope of application of oilcloth.Meanwhile, improve the resistance to water of oilcloth, also very necessary, resistance to water is bad, the use that affects oilcloth that can be serious.

Summary of the invention

The technical problem solving: the common poor problem of oilcloth heat resistance.

Technical scheme: the invention discloses a kind of heat-resisting oilcloth and preparation method thereof, heat-resisting oilcloth comprises burlap and coating, and coating is comprised of according to weight ratio following composition: ethyl acetate is that 3～5 parts, polyvinyl alcohol are that 2～5 parts, abietic resin are that 3～4 parts, diglyceride are that 5～7 parts, polyurethane are that 11～14 parts, polyethylene are 12～15 parts.

A preparation method for heat-resisting oilcloth, preparation method comprises the following steps: (1) gets ethyl acetate is that 3～5 parts, polyvinyl alcohol are that 2～5 parts, abietic resin are 3～4 parts, mentioned component is put into agitator tank and stir evenly; (2) to adding diglyceride in agitator tank, be that 5～7 parts, polyurethane are that 11～14 parts, polyethylene are 12～15 parts again, after adding, stir evenly each composition, prepare coating; (3) get common burlap, with brush by the coating preparing evenly brushing on burlap surface; (4) after brushing, oilcloth is dried, bake out temperature is 90～95 ℃, and drying time is 6～12h.After oven dry, obtain heat-resisting oilcloth.

Beneficial effect: the heat-resisting oilcloth preparing by preparation method of the present invention has good heat-resisting effect and waterproof effect, heats 10h to 20h at can resistance to 120 ℃ unchanged, and soaking-resistant 30h to 40h produces without drainage.

The specific embodiment

Embodiment 1

(1) getting ethyl acetate is that 5kg, polyvinyl alcohol are that 2kg, abietic resin are 4kg, mentioned component is put into agitator tank and stir evenly; (2) to adding diglyceride in agitator tank, be that 5kg, polyurethane are that 11kg, polyethylene are 15kg again, after adding, stir evenly each composition, prepare coating; (3) get common burlap, with brush by the coating preparing evenly brushing on burlap surface; (4) after brushing, oilcloth is dried, bake out temperature is 90 ℃, and drying time is 6h.After oven dry, obtain heat-resisting oilcloth.

Embodiment 2

(1) getting ethyl acetate is that 3kg, polyvinyl alcohol are that 3kg, abietic resin are 3kg, mentioned component is put into agitator tank and stir evenly; (2) to adding diglyceride in agitator tank, be that 7kg, polyurethane are that 12kg, polyethylene are 13kg again, after adding, stir evenly each composition, prepare coating; (3) get common burlap, with brush by the coating preparing evenly brushing on burlap surface; (4) after brushing, oilcloth is dried, bake out temperature is 95 ℃, and drying time is 8h.After oven dry, obtain heat-resisting oilcloth.

Embodiment 3

(1) getting ethyl acetate is that 4kg, polyvinyl alcohol are that 5kg, abietic resin are 3kg, mentioned component is put into agitator tank and stir evenly; (2) to adding diglyceride in agitator tank, be that 6kg, polyurethane are that 14kg, polyethylene are 12kg again, after adding, stir evenly each composition, prepare coating; (3) get common burlap, with brush by the coating preparing evenly brushing on burlap surface; (4) after brushing, oilcloth is dried, bake out temperature is 90 ℃, and drying time is 12h.After oven dry, obtain heat-resisting oilcloth.

It is that the baking oven of 120 ℃ heats 10h, 15h, 20h that the oilcloth of embodiment 1, embodiment 2, embodiment 3 is put into respectively to temperature.Separately get again the oilcloth of embodiment 1, embodiment 2, embodiment 3, put into respectively water and soak 30h, 35h, 40h.

After Heating Experiment finishes, oilcloth performance and the color of embodiment 1, embodiment 2, embodiment 3 are unchanged, have good heat resistance.

After water-fast experiment finishes, the oilcloth of embodiment 1, embodiment 2, embodiment 3 produces without drainage, has good water resistance.
