The invention discloses SBS grafted odor-removing mattress spraying glue and a preparation method thereof. The SBS grafted odor-removing mattress spraying glue comprises, by weight, 10-15 parts of methyl isobutyl ketone, 5-10 parts of isopropyl formate, 10-20 parts of aromatic environment-friendly solvent oil, 15-25 parts of methyl cyclohexane, 10-18 parts of SBS elastomer, 0.1-0.5 part of BPO, 5-15 parts of MMA, 0-8 parts of BA, 0-3 parts of 2-HEMA, 1-3 parts of terminating agent, 10-15 parts of hydrogenated petroleum resin and 12-18 parts of hydrogenated rosin modified resin. The SBS grafted odor-removing mattress spraying glue has the advantages that the glue is colorless, transparent, high in adhesive force, resistant to yellowing, efflorescence, high temperature, oil and plasticizer, nontoxic, odorless and free of residues and is an ideal spraying glue choice for high-end mattress manufacturers, the glue is small in odor during spraying, a glue film is free of residual solvents and resin odor, pure white and transparent, and light-colored mattress fabric cannot polluted after glue spraying.

The invention provides a modified self-adhesive EVA chip and a wall repairing tape, and production methods thereof. The modified self-adhesive EVA chip is produced from, by weight, 90-110 parts of EVAresin, 5-16 parts of synthesized rubber SIS, 12-22 parts of a tackifier, 3-14 parts of petroleum resin, 6-15 parts of terpene resin and 1-7 parts of a coupling agent. The EVA resin is modified to have the self-adhesive properties while having original properties in order to obtain the modified self-adhesive EVA chip; and the wall repairing tape changes the production process of existing self-adhesive material coating, and prevents deformation and performance deterioration of polymeric sheets, caused by traditional roller coating of polymeric materials with a self-adhesive material, and the pollution of high-temperature volatiles of the self-adhesive liquid material to the environment during secondary molding.

The invention relates to the technical field of waterproof construction, and particularly discloses a regenerated waterproof layer construction method. The regenerated waterproof layer construction method comprises the following steps that S1, a water leakage position of a roof plate is determined and marked; S2, drilling and sampling are carried out, the depth of a waterproof layer is determined, and the drilling depth is determined; S3, holes are formed in the periphery of the water leakage position at intervals by taking the water leakage position as the center, and embedded objects in the roof plate is kept away during drilling; S4, waterproof materials are injected into the holes in sequence, and after the single holes are filled with water, corks are plugged into the filled holes; and S5, when all the holes are filled with the waterproof materials, the holes are filled and leveled up with concrete mortar. The waterproof materials are prepared from resin components and hardening accelerators, and the weight ratio of the resin components to the hardening accelerators is 1 to (0.05-0.1); and the resin components are composed of the following components: 35%-45% of petroleum resin, 6%-10% of acrylic resin and the balance of deionized water. According to the regenerated waterproof layer construction method, the waterproof layer damage can be effectively repaired, and the repairing efficiency is high.

The invention discloses a plant-root-pricking-resistant waterproof coil. A PVC (polyvinyl chloride) inner glass fiber strengthened base and a waterproof coating are pressed in a physical mode to form the plant-root-pricking-resistant waterproof coil. The waterproof coating is a modified asphalt waterproof coating. Modified asphalt is asphalt modified via petroleum resin. The plant-root-pricking-resistant waterproof coil has the advantages that the plant-root-pricking-resistant waterproof coil integrates waterproofness and root pricking resistance, resolves the problem that plant roots prick waterproof layers, accordingly is convenient in construction, reduces project cost, and is widely applicable to engineering of urban environment-friendly roofs.
