Embodiment 1

[0037] In Example 1, the mixed monomer consists of the following components by weight percentage:

[0038] (1) Vinylidene chloride monomer, the dosage is 80% of the total weight of mixed monomers;

[0039] (2) For unsaturated fatty acid monomers, the dosage is 5% of the total weight of mixed monomers;

[0040] (3) Acrylic monomers, the dosage is 15% of the total weight of mixed monomers;

[0041] The percentages of the emulsifier, initiator and auxiliary agent in the total weight of the mixed monomer are as follows: emulsifier 2.5%; initiator 0.08%; auxiliary agent 0.005%.

Embodiment 2

[0042] In Example 2, the mixed monomer consists of the following components by weight percentage:

[0043] (1) Vinylidene chloride monomer, the dosage is 85% of the total weight of mixed monomers;

[0044] (2) For unsaturated fatty acid monomers, the dosage is 5% of the total weight of mixed monomers;

[0045] (3) Acrylic monomers, the dosage is 10% of the total weight of mixed monomers;

[0046] The percentages of the emulsifier, initiator and auxiliary agent in the total weight of the mixed monomer are as follows: emulsifier 2%; initiator 0.05%; auxiliary agent 0.006%.

Embodiment 3

[0047] In Example 3, the mixed monomers consist of the following components by weight percentage:

[0048] (1) Vinylidene chloride monomer, the dosage is 75% of the total weight of mixed monomers;

[0049] (2) Unsaturated fatty acid monomers, the dosage is 10% of the total weight of mixed monomers;

[0050] (3) Acrylic monomers, the dosage is 15% of the total weight of mixed monomers;

[0051] The percentages of the emulsifier, initiator and auxiliary agent in the total weight of the mixed monomer are as follows: emulsifier 3%; initiator 0.2%; auxiliary agent 0.009%.

[0052] The preparation method of soft latex for above-mentioned automobile sponge is as follows:

[0053] Feed deionized water, 20% by weight of emulsifier, initiator, and additives into the reaction kettle, vacuumize, fill with nitrogen, inhale the core layer monomer accounting for 10% of the total weight of the mixed monomer as a seed, and stir for half an hour , then the temperature is raised to 55°C, and ...

Abstract

The invention discloses a method for preparing soft latex for automobile sponge. The method comprises the following steps: adding deionized water, 20wt% of emulsifying agent, initiator and aids into a reaction kettle, vacuumizing, introducing nitrogen, inhaling nuclear layer monomer which accounts for 10 percent of the mixed monomer to serve as the seed, and stirring for half an hour; raising the temperature to be 55 DEG C, when the pressure is dropped to zero, pumping the residual nuclear layer monomer and the other 80wt% of emulsifying agent through a metering pump for 8 hours, and when the pressure is dropped to zero, pumping the shell layer monomer through the metering pump for 6 hours, reducing the pressure to be zero after pumping, reducing the temperature to be 30 DEG C or below, and filtering and discharging by using a filtering net with the particle size of 120 meshes. After the latex is coated on a sponge, the tensile strength of the sponge is improved, and low-temperature heat sealability, folding resistance and the like are provided for the sponge.

Description

technical field [0001] The invention relates to a method for preparing soft latex for automobile sponges. Background technique [0002] For cars and buses, interior decoration is required. The car roof, walls and door panels made of rigid materials such as metal and laminate need to be attached with PVC microcellular foam artificial leather, synthetic fiber non-woven fabric, printed or jacquard decorative cloth , sponge, velvet car blanket and other porous soft materials to make the car interior environment beautiful, harmonious and comfortable, sound absorption and noise reduction. Adhesives are required for these interior decorations, and most of these adhesives are solvent-based, which have problems of environmental pollution and harm to human body. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for preparing water-based soft latex for automobile sponges. The water-based soft latex does not have the...
